Negative Pressure Upstream System

    Flowchart of Negative Pressure Upstream System

This system is developed based on the principle of material pneumatic conveying and traditional mixer upstream system, which is mainly applicable to the first or second floor plant. The system retains the advantages of high precision of screw feeding control of traditional mixer upstream system, and uses negative pressure feeding to transport materials to the weighing scale, separating the raw material area from the production area. Using advanced control technology and negative pressure suction, the materials are transported to the weighing scale for weighing. This system ensures no dust pollution and minimizes the investment in the plant. It can be widely used in the production of rubber products, plastic products, cable materials and other products.
