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.

According to the different production processes of emulsified modified asphalt equipments, it can be divided into two types: batch operation and continuous operation. The batch operation is the mixing of demulsifier and water. The demulsifier soap solution is prepared in a container in advance, and then pumped into the black anti-static tweezers with a pump. After one tank of demulsifier solution is used up, the soap solution of the next tank is mixed; the soap solution preparation of the two tanks is carried out in rotation and batch operation; it is mainly used for portable medium and small emulsified asphalt production equipment. The continuous operation type (online production type) is to separate water, demulsifier and other preservatives (acid, calcium chloride) and send them into the black anti-static tweezers with a plunger metering pump, and the mixing of the demulsifier solution is completed in the pipeline. Emulsified modified asphalt equipment can perform large-flow continuous operation; it has the advantages of small storage tank capacity, large annual output value, and high automation technology; According to the different equipment modes of emulsified modified asphalt equipment, it can be divided into two types: mobile and portable. Mobile is used for medium and large emulsified asphalt production equipment in emulsified asphalt production plants; portable is used for medium and small emulsified asphalt production equipment for on-site construction.
