What kinds of raw materials can be made using asphalt mixing plant? - 25 Sep 2019 09:01



At present, many areas need to maintain and construct roads, railways, etc., and in this process, a large amount of asphalt raw materials are needed. In order to ensure the supply of asphalt, asphalt mixing plant can be used to process and produce asphalt raw materials. It can provide people with sufficient asphalt raw materials on time.

Although asphalt is used in many places in life, there is not much understanding of this material. In fact, there are many classifications of asphalt raw materials, and different asphalts can be used in different places.

Then, the asphalt mixing plant can complete the production of several kinds of asphalt raw materials. Now the coal tar pitch used by people can directly complete the production process through the equipment. The color of the coal tar pitch is different from the ordinary asphalt, and the surface is black. Asphalt is sensitive to temperature changes, so pay attention to the environment when using coal tar pitch. When the asphalt is heated at high temperature, it will release pungent odor. Therefore, pay attention to temperature control during production and heating.

Petroleum asphalt is also a relatively common raw material. This kind of asphalt can also be processed by using asphalt mixing plant. Although petroleum asphalt is also black, this black and coal tar pitch is different. The black of petroleum asphalt is more lustrous. Moreover, the tolerance to temperature is relatively strong, and it is not easy to change when encountering the same high temperature conditions, but the odor emitted by asphalt is something that people need to pay attention to because the asphalt contains some toxic substances which are not good for human health.

When the asphalt is produced by the asphalt mixing plant, the raw materials can be added in combination with the use requirements, and the processing flow can be completed according to the correct operation method of the equipment. - Comments: 0

How asphalt mixing plants work - 22 Sep 2019 09:00



How asphalt mixing plants work
Asphalt, a kind of high-viscosity organic liquid, has a black surface and is soluble in carbon disulfide (a golden odorous liquid).

They will often exist in the form of asphalt or tar.

Asphalt can be mainly divided into three types: coal tar pitch, petroleum asphalt and natural asphalt: among them, coal tar pitch is a by-product of coking.

Petroleum asphalt is the residue after distillation of crude oil.

Natural asphalt is stored underground, and some form a mineral deposit or accumulate on the surface of the earth's crust.

Asphalt-type bitumen is obtained by fractional distillation of crude oil. They have the highest boiling point in crude oil and the heaviest substance in crude oil, so they are found at the bottom of the fractionation column.

The bituminous form of bitumen is a substance obtained by subjecting an organic substance (mostly coal) to a dry distillation process.

Asphalt will be used in buildings, such as paving roads.

The paved roads of asphalt and gravel are called asphalt roads. - Comments: 0

What are the common hardware failures in asphalt mixing plants? - 19 Sep 2019 09:00



Asphalt mixing station is a professional equipment with complex systems. It is inevitable that some problems will occur during the use.

So, what are the common hardware failures in asphalt mixing plants, do you know?

(1) Due to the complexity of the system, when different components have problems, the problems may be different.

If during the operation, it is found that the loading of each silo is not accurate, this problem may be caused by the failure of the sensor of the asphalt mixing station. At this time, stop the inspection and replace the new sensor if necessary.

It may also be caused by the seizure of the scale, and the foreign matter should be removed in time.

(B) There is a more common problem, that is, the cold feed device does not work properly.

In this case, there may be multiple reasons. First of all, we may analyze that it may be because the gravel or debris is stuck under the cold material belt. Please do it in time.

It may also be caused by a circuit failure. At this time, it is necessary to check whether the motor control inverter of the asphalt mixing station is abnormal, and whether the line link is normal or not.

There may also be belt slippage and deviation caused by the deviation. For this kind of problem, re-adjust the belt tightness.

(3) There is an abnormal sound during the operation.

Normally, this noise is emitted by the mixer, indicating a problem with the mixer.

This kind of problem may be caused by the instantaneous overload operation, which causes the fixed position of the drive motor to be misaligned. It may also be that the fixed bearing of the equipment is seriously worn and needs to be replaced or repaired.

If the inspection finds that the mixer arm and other parts are seriously worn, it must be replaced in time to avoid affecting the production work.

If the mixer discharge temperature of the asphalt mixing station is not normal, check the cleaning device for any abnormality and keep the temperature sensor clean.

The above is the common hardware failure problem in the operation of asphalt mixing plant. I hope that after learning, we can avoid these problems in the production process and ensure the work efficiency. - Comments: 0

How to determine the material of asphalt mixing plant - 16 Sep 2019 09:00



Determining the material is a necessary stage in the design process of the asphalt mixing plant, and it is also one of the most critical steps, because the material will directly affect the use effect and service life of the entire equipment.

Generally, when we determine the material of the machine, we usually rely on the characteristics of the working medium.

If there are no special requirements, similar mixing equipment is made of carbon steel, which can be applied to most working conditions, as long as the temperature is not higher than 350 ° C, and the price is relatively low.

However, this material cannot be used in asphalt mixing plants. Asphalt is a very good temperature material, it does not meet the high temperature resistance, and the corrosion resistance of carbon steel is poor.

In view of the above requirements, a stainless steel asphalt mixer or a beryllium glass material can be used.

However, no matter which one, there is a finer material classification, so the specific model should be determined according to its own mixing conditions, stirring temperature and corrosiveness. - Comments: 0
