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 links, 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 use the characteristics of the working medium as the basis, and the asphalt mixing plant is of course the same.

Since I haven't paid much attention to the reversing valve in the asphalt mixing plant before, I am helpless about the failure of this device. In fact, the failure of the reversing valve is not very complicated. As long as you know a little about it, you will definitely know how to deal with it?

Generally, the manufacture of emulsified asphalt is to place the mixed soap solution formed by water, acid, emulsifier, etc. in a blending tank, and then transport it to the colloid mill together with asphalt for shearing and grinding to produce emulsified asphalt.

Asphalt spreaders are a type of black pavement machinery. After the gravel layer is spread, rolled, compacted, and evenly leveled, the asphalt spreader is used to spray one layer of asphalt on the clean and dry base layer. After the hot jointing material is spread and evenly covered, the asphalt spreader sprays the second layer of asphalt until the surface asphalt is sprayed to form a pavement.

The screen is one of the components of the asphalt mixing station, which can help the material to be screened, but the screen holes on the screen often get blocked during the operation. I don't know whether it is because of the screen or the material, so I must find out and prevent it.

Usually, the operation object of the asphalt mixing station is asphalt, but if concrete is added to it, how to control the equipment? Let me briefly explain to you how to control the asphalt mixing plant under special circumstances. For concrete with admixtures, the dosage, method of admixture and mixing time must be strictly controlled, because these are important factors affecting the quality of the final product. It cannot be ignored because of the small amount of admixture, nor can it be used as a way to save costs. At the same time, it is strictly forbidden to shorten the mixing time in order to speed up the progress.

Three major classifications of modified asphalt equipment: Three major classifications of modified asphalt equipments Modified asphalt equipment is an industrial equipment used to heat melt asphalt and form water-in-oil asphalt emulsion according to the actual effect of mechanical cutting. Modified asphalt equipment can be divided into three types: portable, transportable and mobile according to equipment, layout and controllability.

Emulsified modified asphalt equipment is divided into two types: open system and closed system according to the different conditions when the asphalt and demulsifier solution enter the black anti-static tweezers: the open system uses a valve to control the flow, and the asphalt and demulsifier are injected into the feeding Buchner funnel of the black anti-static tweezers by their own weight. Its advantages are more intuitive and simple equipment composition. The disadvantage is that it is easy to infiltrate air and generate bubbles, which significantly reduces the annual output value of the black anti-static tweezers; it is mainly used to simplify the production of general emulsified asphalt and simple production equipment.

After the asphalt is mixed in the asphalt mixing plant, it will be discharged through a special discharge system, which is also the last link in the asphalt mixing work. Even so, there are things that need attention.

As the core part of the whole, the design of the control system has been introduced to you, and the next two are about its daily maintenance. Don't ignore this aspect. Good maintenance will also help the control system to function, thereby promoting the use of the asphalt mixing plant.
