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

Synchronized gravel sealing is a process technology for treating cracks in asphalt pavement, and it is currently a road construction and pavement maintenance technology with low energy consumption and high cost performance. Do you know what its six technical features are? If you don’t know, just follow the editor of Sinoroader and take a look.

Precautions during the production of emulsified bitumen equipment. How much do you know about this information? Let’s learn more about it:
When the emulsified bitumen equipment is in production, the viscosity of the bitumen decreases with the increase of temperature. For every 12℃ increase, its dynamic viscosity decreases by about one time. During production, the base bitumen should be heated to liquid state before emulsification. In addition, in order to adapt to the emulsification capacity of the colloid mill, the base bitumen dynamic viscosity is generally controlled to be about 200cst. The lower the temperature, the higher the viscosity, which increases the burden on the bitumen pump and the colloid mill, making it difficult to emulsify; but on the other hand, in order to prevent the demulsification caused by excessive vaporization and evaporation of water in the finished product during the production of emulsified bitumen, it is impossible to heat the base bitumen temperature too high. Generally, the finished product temperature at the outlet of the colloid mill should be controlled to be less than 85℃.

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.

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.

From three aspects, emulsion bitumen equipment has good economic performance:
First, energy saving. The kerosene or gasoline content in diluted asphalt can reach 50%, while the emulsion bitumen plant only contains 0-2%. This is a valuable saving behavior in the production and utilization of white fuel. By simply increasing the viscosity standard of asphalt by adding light oil solvent, asphalt can be poured and spread, and it is hoped that the light oil after use can evaporate into the atmosphere.
Second, versatility. There are many application methods for emulsion bitumen plants, and the appropriate method needs to be selected when applying it. The same emulsion can be used for large-scale sealing and can be used for small-scale pit repair work. Because they can be stored in tanks for a long time, they are very easy to use when applied in remote areas.
Third, it is easy to use. The professional spreading of emulsions requires professional equipment, such as spreaders. Small-area emulsion applications can be directly poured and spread by hand, such as small-area pit repair work, crack fillers, etc. Small quantities of cold mixes only require basic equipment.

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:

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

In modern highway maintenance work, how to repair asphalt pavement quickly and effectively has become one of the key issues. As an advanced repair technology, cold patching technology is very popular because of its convenient construction and remarkable effects.
What is the cold patching process?
Cold patching process, as the name suggests, refers to a technical method for repairing asphalt pavement without heating. This process uses a specially proportioned cold-patch asphalt mixture. This material can maintain good fluidity and adhesion even at lower temperatures, thus ensuring the quality of the repair.
Advantages of cold patching process
Fast construction: Cold patching materials can be directly applied to damaged areas without preheating, and are immediately open to traffic, greatly shortening repair time.
All-weather construction: Whether in hot summer or cold winter, cold patching materials can be effectively constructed and are not affected by the weather.
Easy to operate: Thanks to its good working properties, even small damaged areas can be repaired easily.
Environmentally friendly: The construction process reduces environmental pollution and is in line with the concept of green construction.
Application scenarios
The cold patching process is suitable for various types of pavement repair work, especially those places where traffic needs to be restored quickly, such as urban main roads, highway ramps, etc. In addition, the cold patching process is also an ideal choice for remote areas or situations where professional heating equipment is lacking.
In short, the cold patching process has occupied a place in the field of rapid repair of asphalt pavement with its unique advantages and has become an indispensable part of modern highway maintenance.

There are many types of emulsified asphalt (composition: asphaltene and resin) equipment. Emulsified asphalt (composition: asphaltene and resin) equipment can be divided into intermittent operation type, semi-continuous operation type, and Continuing the three operating types, what is the knowledge about different types of emulsified asphalt equipment?

Bitumen emulsifier is a surfactant. A surfactant is a compound that reduces the surface tension between two liquids, a gas and a liquid, or a solid and a liquid. Surfactants are mainly used in: detergents, detergents, fabric softeners, wetting agents, emulsifiers, foaming agents, dispersants, adhesives, etc.

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.

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.

1. Observation: Pay attention to the dynamics of the road surface after milling (three to four days), and pave the milled and roughened road surface in time when paving conditions are met.
2. On-site mixing: During construction and production, a sealing slurry truck should be used for on-site mixing. Through the metering equipment of the sealing truck and on-site operation by a robot, it is ensured that emulsified asphalt, water, mineral materials, fillers, etc. can be mixed according to a certain proportion. , stir through the mixing box, and the paving thickness is not higher than the roughing depth.

Conventional pit repair techniques are mainly hot material repair and cold filling repair, and warm mixing technology is used to ensure compaction, while there are also some special repair methods such as slurry seal/micro-surface material repair

There are many types of emulsified bitumen, and PC-2 is one of them, which is a spray-type emulsified bitumen. It is used for spraying oil through the base layer of granular materials and health care spraying on semi-rigid base layers. There is also the PA-2 type, which has the same purpose as the PC-2 type. The difference is that the PC-2 type is a cation, while the PA-2 type is an anion.

This set of mechanical equipment includes wastewater treatment, water storage tank, automatic water measurement and verification temperature control system, asphalt storage tank, asphalt external temperature system, hot water pump soap condiment system, soap storage tank, soap mixing pump, soap external It is composed of temperature system and measurement verification system, filtration system, hot asphalt mixing pump and measurement verification system, three-stage pipeline-type black antistatic medical tweezers, emulsified asphalt cooling system and retrieval machinery, and automatic control system for commercial tanks and electrical equipment.

The heating principle of asphalt decanter equipment is to heat, melt and decanter the asphalt through the heating plate. It is mainly composed of de-barreling box, lifting system, propeller and electrical control system.
The box of asphalt decanter plant is divided into upper and lower chambers. The upper chamber is the asphalt melting chamber, which is densely covered with heat transfer oil heating coils or hot air heating pipes. The asphalt is melted and removed from the barrel by heat. The hoisting hook is installed on the gantry, and a barrel grabber is hung. The asphalt barrel is lifted by the electric winch, and then the asphalt barrel is placed on the guide rail by horizontal movement. Then the propeller pushes the barrel into the upper chamber through two guide rails, and an empty barrel is pushed out at the rear end outlet.
An anti-drip oil tank is provided at the entrance of the asphalt barrel. The asphalt enters the lower chamber of the box and is continuously heated to a temperature of about 100 to be transported, and then pumped into the asphalt tank by the asphalt pump. The lower chamber can also be used as an asphalt heating tank.
The asphalt decanter plant has the characteristics of not being restricted by the construction environment, strong adaptability and extremely low failure rate. If large production is required, multiple units can be assembled.

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.

Analysis of the necessity of emulsified bitumen equipment in modern road construction projects With the acceleration of the construction speed of transportation infrastructure, the construction standards are getting higher and higher, and higher requirements are also put forward for the use of emulsified bitumen in the closed layer of fly ash and the adhesive layer between the new and old ground.

There are many types of bitumen emulsifiers, and there are many classification methods. For specific classifications, please refer to previous articles. The raw materials required for the production of emulsion bitumen are: bitumen, water and bitumen emulsifier. High-standard emulsion bitumen requires adding additives and adjusting acid. According to whether acid adjustment is needed in the emulsion bitumen production process, it can be divided into two categories: emulsion bitumen that requires acid adjustment and emulsion bitumen that does not require acid adjustment.

Contemporary roads and pavements have undergone many changes: traffic volume and driving frequency have increased significantly, the axle load of logistics trucks has continued to increase, one-way driving in separate lanes has been widely implemented, and regulations have further improved the anti-flow resistance of the ground, that is, the work of modified asphalt equipment under high temperatures ability;

How to reduce energy consumption of emulsified asphalt machinery is a concern of many users and many manufacturers. Therefore, today, Sinosun Company, as a manufacturer of emulsified asphalt equipment, would like to take this opportunity to share with you the method of reducing energy consumption of emulsified asphalt machinery.
Since emulsified asphalt appears as a finished product in emulsified asphalt machinery, and the outlet temperature of ordinary emulsified asphalt is about 85℃, and the outlet temperature of emulsified modified asphalt is above 95℃, there is a lot of latent heat in emulsified asphalt, but the emulsified asphalt equipment does not make good use of them, but directly enters the finished product tank, allowing heat to be lost at will, resulting in energy waste.

The slurry seal truck is one of the main maintenance methods of highways. The slurry seal is made of emulsified asphalt as the binding material, well-graded mineral materials, fillers, water and additives, etc., mixed in a certain proportion. The slurry mixture is evenly spread on the old road surface to be treated with a sealing truck, and is firmly combined with the original road surface to form a new thin layer of asphalt mixture. So what preparations need to be done before construction? Let’s find out below.

● The spreading amount is accurate, and three overlapping asphalt sprayings can be achieved with good uniformity;
● Intelligent control of spreading amount, real-time monitoring of spreading amount and vehicle speed, closed-loop control;
● Full computer touch screen operation, equipped with video monitoring system, the entire work process can be observed at any time;
● Reliable performance, durability and easy operation;

Regarding the basic knowledge of modified bitumen plant, I believe that many consumers have already had a basic understanding of it. Because of the continuous development of various fields today, various facilities including modified bitumen plants have been well developed and applied, and modified bitumen plant has gradually been recognized by customers.
The direct quick heating portable equipment in the modified bitumen equipment not only has a faster heating speed, saves fuel, and is pollution-free, but also convenient and easy to operate. The automatic heating system completely eliminates the trouble of baking or cleaning bitumen and pipelines.

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.

Everyone has a side of themselves that they don’t want others to know. As a preventive road maintenance technology, slurry sealing has some shortcomings. do you think so?
Slurry seal is a kind of road protection that uses special equipment to mix emulsified asphalt, water, additives, aggregates, fillers and other ingredients in a certain proportion, and then mixes the slurry mixture onto the original road surface to form a thin layer. Maintenance technology. These are all well known. The editor will not go into details on this.

For users of equipment, the amount of material used is the focus of every user. We should attach great importance to this link in the production process. The following is an analysis of the amount of emulsifier used by Gaoyuan manufacturers.
When emulsified asphalt equipment is emulsifying asphalt, the asphalt temperature is better controlled at above 130°C to have better fluidity; 2. The amount of emulsifier is generally 8-14‰ of emulsified asphalt, that is, 8-14kg per ton of emulsified asphalt (asphalt content is more than 50%), and the temperature is 60-70°C. The emulsifier should be used in the middle and upper limit of the production, 10 kg per ton of emulsified asphalt, or 20 kg per ton of water (asphalt content is 50%); the amount of BE-3 emulsifier is generally 18-25‰ of emulsified asphalt, that is, 18-25kg per ton of emulsified asphalt (asphalt content is more than 50%), and the emulsifier solution temperature is 60-70°C. The emulsifier should be used in the upper and middle limits in the first production to ensure successful production. Use 24 kg per ton of emulsified asphalt, or 48 kg per ton of water (asphalt content is 50%). After the production goes smoothly, the dosage can be reduced according to actual conditions.

Modified bitumen equipment uses modified bitumen colloid mill. Its blade has high hardness, high linear speed of the moving disk, and the gap can be adjusted to 0.15mm. It is suitable for processing various polymer-modified bitumens, such as SBS, PE, EVA, etc.
