What configurations are used in stainless steel bitumen melter plant? How is it different from traditional equipment?

Emulsion bitumen manchine is widely used in new technologies and new processes for preventive maintenance. Emulsion bitumen manchine is an emulsion at room temperature formed by dispersing asphalt into the water phase. It is a new material that is made of natural materials. It is different from traditional Compared with hot asphalt, it saves more than 50% of energy, saves 10%-20% of asphalt, and causes less pollution.

With the rapid development of our country’s social development and the continuous development of economic and information technology, modern highway construction is also developing rapidly, and the requirements for ground structural materials are becoming higher and higher, and Asphalt concrete bonding raw materials are inseparable from modified asphalt equipment. So besides these influencing factors, what other reasons does the company have that people don’t understand? Let’s analyze it together.
There are some asphalt concrete equipment on the market, because they have not solved the problem of asphalt clogging before grinding, there are not enough preparation equipment and grinding equipment, the structure is unscientific, and the entire grinding process cannot achieve a certain particle size, resulting in modification. The product productivity of asphalt equipment is low and the product quality is unstable. It requires continuous grinding for a long time, creating problems. This will not only greatly increase energy consumption, increase costs, make product quality unstable, and affect the speed of highway construction.

Modified (rubber powder) bitumen equipment, one of the road maintenance equipment. It is a kind of equipment that measures, mixes and develops SBS, rubber powder and asphalt.
Modified (rubber powder) bitumen equipment is a set of wet modification processing technology, which mainly consists of modified material metering and promotion, bitumen rapid heating, asphalt metering, high-intensity mixing tank, mixed material transfer pump, development tank, colloid mill, Control system and other components.

In our daily life, we can often see emulsified asphalt equipment. Its appearance has brought us great convenience. So what is the difference between its modification process? Below, the editor will give you a brief introduction to the relevant knowledge points.
1. Emulsified asphalt equipment first emulsifies and then modifies: This is a relatively simple way to make modified emulsified asphalt. The production process is to grind hot asphalt and emulsifier soap together through a colloid mill to make ordinary emulsified asphalt, and then add latex-like modifiers to the emulsified asphalt through mechanical stirring to make modified emulsified asphalt. The characteristic of this method is that it does not require high equipment.

Colored asphalt pavement is a kind of special pavement material that mixes colored particles into asphalt and then lays on the pavement

As we all know, emulsified bitumen is a single-component black viscous liquid that can combine the roadbed and the pavement to improve the performance and service life of the road. So what problems should be paid attention to when using emulsified bitumen? Let’s follow the editor of Sinoroader Group, an emulsified bitumen manufacturer, to learn about it.

As a manufacturer with many years of experience in emulsified bitumen construction, Sinoroader Group believes that everyone needs to pay attention to the following 2 points when using it:

Sinoroader emulsifier does not need to add acid or adjust pH value in the production of emulsified asphalt, thus reducing the process, reducing equipment maintenance, saving labor and materials. It reduces the cost of emulsified asphalt, produces acid-free, eliminates equipment corrosion emulsion, does not consider anti-corrosion measures in the selection of equipment, and greatly reduces the capital investment of equipment.
Main technical indicators:
Active ingredient content 40±2%
pH value 8-7
Appearance: yellow or dark yellow liquid
Odor: non-toxic, aromatic gas
Solubility: soluble in water and some organic solvents
Temperature ratio:
Water temperature: 70℃-80℃
Asphalt temperature: 140℃-150℃

When the temperature is low, the product is in a paste or paste, and the heating is variable.
Different varieties of asphalt should adjust the amount of emulsifier, and the use test should be derived from the test.

Recently, I found that many people don’t know much about the operation skills of asphalt pavement spreaders. If you also want to know what’s going on, you can read this introduction below.
Asphalt pavement spreaders are an indispensable and important equipment in road maintenance and construction. Their operation skills directly affect construction efficiency and project quality. The following introduces the operation skills of asphalt pavement spreaders from four aspects: pre-operation preparation, precautions during construction, spreading skills, and post-operation cleaning and maintenance:

Asphalt spreader is an irreplaceable tool for highway maintenance. Asphalt spreader is an irreplaceable tool for highway maintenance. Highway maintenance is divided into four categories according to the nature of the project, scale, and technical complexity: minor repair, medium repair, major repair, and improvement. Specific classification:
(1) Minor repair and maintenance project: preventive maintenance and repair of slightly damaged parts of the highway and all its engineering facilities to keep them in good condition. It is usually planned and carried out daily by the maintenance team within the annual minor repair and maintenance quota funds on a monthly (ten-day) basis.
(2) Medium repair project: regular repair and reinforcement of general wear and tear and local damage of highway engineering facilities to restore them to their original state. It is usually planned and implemented by grassroots road maintenance agencies on an annual (seasonal) basis.
(3) Major repair project: periodic comprehensive repair of major damage to highway facilities to fully restore them to the original design standards, or local improvements and individual additions within the original technical level to gradually improve the highway’s traffic capacity. It is usually organized and implemented by grassroots road maintenance agencies or with the help of their superior agencies according to the approved annual project budget.
(4) Improvement projects are large projects that improve the technical level of roads and their engineering facilities in stages and sections due to their inability to meet traffic volume and load requirements, or significantly improve traffic capacity through improvements. It is usually organized and implemented or completed through bidding by regional road maintenance agencies or provincial road maintenance agencies according to the approved plan and design budget. As a manufacturer of asphalt spreaders, we welcome you to visit us.

Here is an introduction to the knowledge on construction quality control of modified rubber asphalt equipment. Let’s introduce this knowledge from three aspects. The details are as follows: The viscosity of the modified asphalt mixture of modified rubber asphalt equipment is relatively high, and the construction temperature of each process is The construction temperature requirements are higher than those of ordinary asphalt mixtures.

The main filter material of stainless steel barrel removal adopts five-layer sintered mesh. Standard five-layer calcination is made by stacking and vacuum calcining five layers of stainless steel barrel removal wire mesh. The stainless steel barrel made of it has corrosion resistance, good water permeability, high compressive strength, easy cleaning and back-cleaning, high filtration precision, hygienic and clean filter material, and stainless steel barrel removal wire mesh does not fall off.
Double-layer metal sintered mesh is a new type of filtration system with high impact toughness and overall rigidity, which is made by stacking and vacuum calcining double-layer stainless steel barrel removal wire mesh products.

The black anti-static tweezers grinding wheel of the emulsified asphalt equipment does not have a heated collet. Before use, you must add the appropriate amount of diesel and let the black anti-static tweezers circulate for 3 to 5 minutes to generate heat (the temperature after operation is 80 ~100 degrees) Open the stop valve on the oil delivery pipe to drain the diesel engine in the engine. The temperature of the black anti-static tweezers grinding wheel must be around 80 to 100 degrees before the material can be loaded and put into production. If there is a heated collet, the grinding wheel must be heated before starting, and then the material is loaded and put into production.

There are many ways to heat bitumen, including using fire source heating, electric heating, steam heating, hot water heating and indirect heating. Fire source heating generates heat by burning fuel to heat the bitumen to a molten state. Electric heating converts electrical energy into thermal energy through electric heating elements to heat the bitumen to a molten state. Steam heating transfers heat to bitumen through steam, heating the bitumen to a molten state. Hot water heating transfers heat to the bitumen through hot water, heating the bitumen to a molten state. Indirect heating transfers heat to the heating medium, which then transfers the heat to the bitumen to heat the bitumen to a molten state.

Asphalt melting equipment follows the continuous development of urbanization. Whether in rural areas or in big cities, you can see a lot of construction sites, among which it is inevitable that asphalt melting equipment is set up nearby. Asphalt melting equipment manufacturers, whether large or small asphalt melting equipment or relatively large and small, although it is just a simple mechanical equipment, but to move or transport it, it is a small matter, and there are many places that require attention.
The technical level of the asphalt melting equipment disassembly and assembly team directly affects the disassembly and assembly progress of the asphalt melting equipment; improve on-site supervision, reasonably organize disassembly and assembly machinery and equipment and workers, try to avoid cross-operation, and promote the disassembly and assembly process to consume less manpower and machinery shifts to do a good job in the transportation of asphalt melting equipment; ensure that the asphalt melting equipment is not damaged and the prefabricated components are not missed.

When using asphalt melting equipment, you need to pay attention to the following points:
1. The power must be cut off during installation and operation to ensure safety.
2. Before starting operation, check whether all components are normal and have no fault prompts. In particular, the inspection of key parts such as the heater part and the conveyor belt device is particularly important.

Asphalt melting equipment is a mechanical equipment specially used to heat and melt asphalt. Our company’s products have been widely recognized and applied in the market.
Our main production process is: transporting the high-temperature oil and gas generated after high-temperature cracking of raw materials (such as petroleum) in the combustion chamber to high-speed rotating heat-conducting oil tankers for heat transfer, melting, cooling and other processes, and finally obtaining the required finished materials or Semi-finished materials. The advantage is that it can make the best use of raw materials and reduce energy consumption; at the same time, it can also customize products of different specifications according to different needs to meet the different requirements of customers. In addition, we provide after-sales service and technical support to protect the interests and safety of our customers.

Before use, please check whether the position of each valve is accurate and make preparations before work. After starting the motor of the asphalt spreading truck, check the four thermal oil valves and air pressure gauge. After everything is normal, start the engine and the power take-off starts to work. Try running the asphalt pump and cycle for 5 minutes. If the pump head shell is hot to your hands, slowly close the thermal oil pump valve. If the heating is insufficient, the pump will not rotate or make noise. You need to open the valve and continue to heat the asphalt pump until it can operate normally.

Emulsified asphalt equipment is a special equipment for producing emulsified asphalt. The emulsified asphalt produced by emulsified asphalt equipment is used in many industries. I wonder how much you know about the emulsified asphalt produced by emulsified asphalt equipment. Let’s take a look at them one by one:
Slurry seal is a cold mix asphalt mixture with the advantages of aggregate and asphalt mixing. Under normal circumstances, similar graded slurry seal has a higher modulus than hot mix asphalt mixture, so it is often used to fill road rutting. The higher stability has a higher resistance to deformation. The mixture is usually composed of harder fine aggregate grading and wear-resistant aggregate with high sand equivalent, especially micro-seal and polymer-modified seal. This greatly increases the strength and integrity of the road surface. This makes the road surface have high wear resistance and excellent deformation resistance. Emulsified asphalt emulsion is also easy to use on a mobile slurry seal paver, where mixing and admixtures are used for chemical control to meet maintenance needs.

What is the overall operation process of bitumen (composition: asphaltene and resin) drum melting equipment?
The bitumen (composition: asphaltene and resin) drum melting equipment produced by our company mainly uses barrel debarking and melting of large barrels of bitumen (definition: the transformation process of materials from solid to liquid), using high-temperature thermal oil as the material (playing a decision-making role substance), used in supporting facilities of high-temperature thermal oil heating equipment. Bitumen drum melter equipment has the functions of barrel delivery, barrel removal, storage, temperature raising, slag discharge, etc. It is an essential product for high-grade highway construction companies. Bitumen drum melter equipment can be used for resin barrel removal. The bitumen drum melter equipment mainly consists of barrel removal shell, hoisting mechanism, hydraulic booster and electrical control system.

Abstract: Asphalt melting equipment is one of the indispensable equipment in modern road construction. Its main function is to heat a large amount of cold hard asphalt to a suitable working temperature at the construction site. Advanced asphalt melting equipment can greatly improve construction efficiency, reduce human resources and time costs, and ensure pavement quality at the same time.

Stainless steel bitumen melters use bitumen concrete micro-powder machines. Its blade strength is high, the angular velocity of the moving disc is high, and the gap can be adjusted to 0.15mm. Stainless steel bitumen melters are suitable for the production and processing of various polymer bitumen concrete, such as SBS, PE, EVA, etc.
Stainless steel bitumen melters use independently developed special batching tanks, stainless steel bitumen melter force stirring devices, liquid level meter overflow prevention equipment, granular material dosage and equipment, liquid additive automatic addition equipment and other production key points. It ensures the full-position process guarantee for the stainless steel bitumen melter of the bitumen concrete production line. The stainless steel bitumen melter processing stainless steel bitumen melter rate is significantly increased, and the quality of stainless steel bitumen melters is greatly improved.

Asphalt spreader is used to spread the penetration oil, waterproof layer and bonding layer of the bottom layer of asphalt pavement of high-grade highway. It can also be used for the construction of county and township highway oil roads with layered paving technology. It consists of a car chassis, an asphalt tank, an asphalt pumping and spraying system, a thermal oil heating system, a hydraulic system, a combustion system, a control system, a pneumatic system, and an operating platform.
Knowing how to properly operate and maintain the asphalt spreader can not only extend the service life of the equipment, but also enable the construction project to proceed smoothly. So what problems should the asphalt spreader pay attention to when working? The technicians of Gaoyuan Road Construction Machinery Equipment Co., Ltd. give you tips:
1). Before use, please check whether the position of each valve is accurate and make preparations before work. After starting the motor of the asphalt spreader, check the four thermal oil valves and the pressure gauge. After everything is normal, start the engine and the power take-off starts to work. Test the asphalt pump and circulate for 5 minutes. If the pump head shell is hot, slowly close the thermal oil pump valve. If the heating is insufficient, the pump will not turn or make noise. In this case, the valve needs to be opened to continue heating the asphalt pump until it can operate normally. During the working process, the asphalt liquid must be kept at a working temperature of 160~180℃, and it cannot be filled too full (pay attention to the liquid level pointer during the injection of asphalt liquid, and check the tank mouth at any time). After the asphalt liquid is injected, the filling port must be closed tightly to prevent the asphalt liquid from overflowing during transportation.
2). During use, asphalt may not be pumped in. At this time, it is necessary to check whether the interface of the asphalt suction pipe is leaking. When the asphalt pump and pipeline are blocked by solidified asphalt, a blowtorch can be used for baking, and the pump must not be forced to turn. When baking, care should be taken to avoid directly baking the ball valve and rubber parts.
3). When spraying asphalt, the car should be driven at a low speed. Do not step on the accelerator hard, otherwise it may cause damage to the clutch, asphalt pump and other components. If 6m wide asphalt is spread, pay attention to obstacles on both sides at any time to prevent collision with the spreading pipe. At the same time, the asphalt should be kept in a large circulation state until the spreading work is completed. After the work is completed every day, if there is any remaining asphalt, it must be returned to the asphalt pool, otherwise it will solidify in the tank and cannot work next time.
4). In addition, the emulsifier must also pay attention to daily maintenance:
1. The emulsifier and delivery pump and other motors, agitators, and valves should be maintained daily.
2. The emulsifier should be cleaned after work every day.
3. The speed regulating pump used to control the flow should be regularly tested for accuracy, and adjusted and maintained in time. The asphalt emulsifier should regularly check the matching clearance between its stator and rotor. When the minimum clearance specified by the machine cannot be reached, the stator and rotor should be replaced.
4. If the equipment is out of use for a long time, the liquid in the tank and pipeline should be emptied (the emulsifier aqueous solution should not be stored for a long time), the hole covers should be tightly closed, kept clean, and the running parts should be filled with lubricating oil. When it is used for the first time or when it is used again after a long period of inactivity, the rust in the tank should be removed, and the water filter should be cleaned regularly.
5. Regularly check whether the terminal in the electric control cabinet is loose, whether the wires are worn during shipment, and remove dust to avoid damage to the machine parts. The frequency converter is a precision instrument. Please refer to the instruction manual for specific use and maintenance.
6. There is a heat transfer oil coil in the emulsifier water solution heating stirring tank. When injecting cold water into the water tank, the heat transfer oil switch should be turned off first, and then the switch should be turned on to heat after adding the required amount of water. Pouring cold water directly into the high-temperature heat transfer oil pipeline can easily cause the weld to crack.

Each F1 track must be paved with three layers of asphalt, middle and lower, of which the lowest layer is 10 cm coarse asphalt concrete bearing layer, its flatness is less than 8 mm; In the middle is a 4 cm medium grained asphalt concrete bond layer, its flatness is less than 5 mm; The top layer uses 4 cm modified asphalt mixture as the surface wear layer, and the flatness is less than 2 mm.

The paved F1 track cannot have more than 3 points per kilometer of flatness detection, which is much higher than the highway.

In addition to being used according to regulations, modified bitumen equipment should also be maintained regularly in order to effectively extend the service life of modified bitumen equipment. The delivery pump of modified bitumen equipment, as well as its motor and reducer, need to be maintained in accordance with the specifications of the instructions. If the modified bitumen equipment is parked for a long time, the liquid in the tank and pipeline needs to be drained, and each moving component also needs to be filled with grease. The dust in the control box of the modified bitumen equipment needs to be cleaned once every six months. A dust blower can be used to remove dust to prevent dust from entering the machine and damaging parts. The micro powder machine needs to add unsalted butter once for every 100 tons of emulsified bitumen produced.

Due to the incorporation of a certain proportion of water into the slurry sealing mixture, it is easy to evaporate in the air. After the water is evaporated, it will become dry and hardened. Therefore, after the slurry is formed, it not only looks very similar to fine-grained asphalt concrete, but does not affect the visual appearance of the road. It also has the same technical properties as fine-grained concrete in terms of wear resistance, anti-skid, waterproofing, and smoothness. Slurry seal technology is used in highway pavement maintenance because of its simple construction technology, short construction period, low cost, high quality, wide application, strong adaptability, etc. It is an asphalt with both economy and high efficiency. Pavement maintenance technology is worthy of application and promotion.

There is a wide variety of asphalt melting equipment on the market, including different brands and models. The prices of these devices vary widely, depending mainly on factors such as their features, performance, and specifications.
Asphalt melter equipment produced by some large brands such as Sinoroader usually has higher quality and reliability, so the price is relatively higher. However, they also offer longer service life and better maintenance support.

What details should be paid attention to when adding materials to the emulsified bitumen equipment? Speaking of emulsified bitumen equipment, I don’t know how much you know? What should we pay attention to when adding materials?
The black anti-static tweezers grinding wheel of the emulsified bitumen equipment has no heating barrel. Before use, you must first add an appropriate amount of diesel, let the black anti-static tweezers circulate for 3 to 5 minutes to generate heat (the temperature after operation is about 80 to 100 degrees) Open the shut-off valve on the oil pipe and discharge the diesel in the machine. The temperature of the black anti-static tweezers grinding wheel is about 80 to 100 degrees before it can be loaded and put into production. If there is a heating collet, heat the grinding wheel before starting, and then load the materials for production.

Asphalt used to pave roads. It can be obtained by regular vacuum distillation of crude oil with appropriate properties, and can also be obtained by shallow oxidation of vacuum residue or propane deasphalting process. It can also be prepared by mixing asphalt of different duction and injection degree

The requirements for SBS asphalt emulsification equipment are very high. The micro powder machine must have a sufficiently large driving force and can bear the condensation type. Because the temperature requirements of the emulsion SBS asphalt process are relatively high, the emulsified asphalt should be passed through a heat exchanger before feeding to reduce the emulsified asphalt temperature to below 90°C to prevent the emulsified asphalt from breaking due to excessive temperature.
The application scope of SBS modified emulsified asphalt is very wide. According to the nature of the construction, it can be used in new construction, renovation, and reconstruction projects; according to the nature of the project, it can be used in overhaul, equipment overhaul, and maintenance projects. Among them, the actual application projects include micro-surfacing, cold regeneration, cold mixing and cold paving, adhesive layer, permeable oil, slurry seal, gravel permeable layer, fog permeable layer, road moisture-proofing, SBS membrane, ground seam filling, and all other projects that can use emulsified asphalt.
