Use of powder materials, transport vehicles: use of national quality of this car made of two types of chassis modifications, mainly for construction sites, transportation of ash powder physical properties of similar materials. Second, the working principle: the use of the car powered air compressor, compressed air tank through pipes into the lower chamber sealed, so that the bed chamber of the liquid suspension into the flow of powder-like, when the tank pressure reaches rating, open the discharge valve, the flow of material flows through the pipeline to transport, the three, the basic structure: 1. Chassis. 2 power take off. 3, the air compressor. 4 air pipe. 5 tanks. Uninstall feeding device 6.
