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.

When the asphalt mixing plant is running, combustion oil will be used, but combustion oil is divided into different grades. If it is used correctly, it is the key to master. The following is the specification for the use of combustion oil in asphalt mixing plants, please be sure to comply.

The asphalt mixing plant is one of the main equipment for producing asphalt concrete. It can mix asphalt, gravel, cement and other materials in a certain proportion to obtain the products required for highway construction. In order to ensure its operating effect, the asphalt mixing plant also needs to be powered on for test run before it is officially put into work.

As a beginner in the highway maintenance industry, today we will learn about the difference between emulsified asphalt and modified asphalt that we commonly use in highway maintenance construction.
First of all, the obvious difference between emulsified asphalt and modified asphalt is that emulsified asphalt has water, while modified asphalt does not.
Emulsified asphalt disperses hot asphalt into water (oil in water) or water into asphalt (water in oil) through an emulsifier to form a temporarily stable emulsion. The continuous phase is water and the dispersed phase is asphalt. Asphalt exhibits solid-like properties at room temperature and liquid-like properties at high temperatures. Therefore, after asphalt is dispersed in water, it can be used at room temperature, which is the biggest advantage of emulsified asphalt. In a word, the asphalt heated to liquid is mixed with an emulsifier, stabilizer, acid or alkali by a colloid mill to obtain emulsified asphalt.
