asphalt mixer

Bitumen, a black or brown petroleum-like material, has a viscosity ranging from a viscous liquid to a glassy solid. It can be obtained as a residue separated from natural deposits. Bitumen consists of hydrogen and carbon compounds with small amounts of nitrogen, sulfur and oxygen. The preparation of mixed materials for mixing with asphalt is done in several steps:
Prediction: According to the asphalt recipe, the individual components of the aggregate are weighed. Usually this is done using a belt scale, since the material must go to the next step in a continuous flow.

The drive unit is one of the important components of the asphalt mixing plant, so whether it can be reliably operated must be highly valued to avoid adverse effects on the entire asphalt mixing plant. In order to ensure that the drive unit in the asphalt mixing plant is indeed complete and reliable, the following maintenance measures are essential.
The first thing to pay attention to is the universal rotating part of the drive unit of the asphalt mixing plant. This part has always been a fault-prone part. In order to reduce the occurrence of faults, grease should be added on time, and the wear should be checked frequently, and repaired and replaced in time. Users should also prepare the universal shaft assembly to avoid affecting the working process of the entire asphalt mixer.
Secondly, the cleanliness of the hydraulic oil used in the asphalt mixing plant must be ensured. After all, the working environment of the equipment is relatively harsh, so it is necessary to prevent sewage and mud from entering the hydraulic system. The hydraulic oil should also be replaced regularly according to the requirements of the manual. Once water or mud is found mixed in the hydraulic oil during inspection, the hydraulic system should be stopped immediately to clean the hydraulic system and replace the hydraulic oil.
Since there is a hydraulic system, of course, a matching cooling device is also required, which is also an important focus in the drive system of the asphalt mixing plant. To ensure that its function can be fully exerted, on the one hand, the hydraulic oil radiator should be cleaned regularly to prevent the radiator from being blocked by cement; on the other hand, the radiator electric fan should be checked to see if it is running normally to prevent the hydraulic oil temperature from exceeding the standard.
In general, as long as the hydraulic oil of the asphalt mixing plant drive device is kept clean, there are generally few faults; but the service life varies from manufacturer to manufacturer, so pay attention to its alkalinity observation and replace it in real time.

Many people think that since both asphalt mixing plants and asphalt mixing plants are equipment for producing asphalt, there should be no difference between them, even if there is, it is only in appearance and volume. However, asphalt mixing plants and asphalt mixing plants are different in even their basic structure and function.
First, let me introduce the basic structure of an asphalt mixing plant, which includes five major components: material supply system, metering system, mixing system, and electrical control system. In comparison, the structure of an asphalt mixing plant is simpler, without so many components, so its operation and maintenance will be simpler.

Oscillating screen. It can screen the heated aggregate according to the design. It requires fully enclosed, double oscillating motor replacement (replacing one substance for another (mostly the strong one takes the place of the weak)) eccentric shaft oscillation, each The layer screen is easy to install quickly. The service life of the drying roller and the power part is not less than 6000h. The roller can fully use heat, the material curtain flows evenly, and the inclination is required to be adjustable.

There is also a reversing valve in the asphalt mixer, which generally does not cause problems, so I have not understood its solution in detail before. But in actual use, we encountered this kind of failure. How should we deal with it?

Asphalt mixing equipment has a special function, which is that it can perform cyclic heating to make the asphalt product reach the best condition. But how does it achieve this function? Everyone is curious about this.

Safety is the key point for any piece of equipment, and asphalt mixers are of course no exception. What I want to share with you is the knowledge in this area, that is, the safe operation specifications of asphalt mixers. You might as well pay attention to it.
In order to prevent the asphalt mixer from moving during work, the equipment should be placed in a flat position as much as possible, and at the same time, use square wood to pad the front and rear axles so that the tires are elevated. At the same time, the asphalt mixer must be provided with secondary leakage protection, and it can only be started after the inspection, trial operation and other aspects are qualified.
