What are the processes and functions of emulsified asphalt equipment?

   Emulsified asphalt equipment is classified according to the process flow and can be divided into three types: intermittent operation type, semi-continuous operation type and continuous operation type. The batch modified emulsified asphalt equipment is prepared by blending an emulsifier, an acid, a water, and a latex modifier in a soap-blending tank, and then pumping it into the colloid mill. After a can of soap is used up, the soap is dispensed and the next can is produced. When used in the production of modified emulsified asphalt, depending on the modification process, the latex pipe can be connected before the colloid mill or after the colloid mill, or there is no special latex pipe, but the latex of the specified dose is manually mixed. Add to the soap tank.

    It is equipped with a soap-blending tank, so that the soap can be alternately blended to ensure uninterrupted feeding of the soap into the colloid mill. A considerable amount of emulsified asphalt production equipment in the country belongs to this type.

    The continuous emulsified asphalt machinery directly pumps the emulsifier, water, acid, latex modifier and asphalt to the colloid mill by means of a metering pump. The blending of the soap is done in the transfer line.

    Classified by device configuration

    According to the configuration, layout and maneuverability of the equipment, the asphalt emulsification equipment can be divided into three types: mobile, transportable and fixed.

    a. The mobile emulsified asphalt equipment is to fix the emulsifier blending device, the emulsifier, the asphalt pump, the control system and the like on a dedicated tray chassis. Since the production site can be transferred at any time, it is suitable for the preparation of emulsified asphalt at the construction site with scattered engineering, low dosage and frequent movement.

    b. The movable emulsified asphalt equipment is installed in one or two standard containers, which are respectively loaded and transported to realize the transfer of the construction site, and the quick installation and assembly of the hoisting tools are combined into a working state. The capabilities are large, medium and small. Can meet different engineering requirements.

    c. Fixed emulsified asphalt equipment generally relies on asphalt storage tanks such as asphalt plants or asphalt concrete mixing stations to serve a relatively fixed customer base within a certain distance. Due to the suitability of China's national conditions, the fixed emulsified asphalt equipment is the main type of emulsified asphalt equipment in China.
