The working principle of the primary cleaning screen is that the material falls into the chute from the feeding mechanism, passes through the running circular screen, and the rough and impurities screened out by the circular screen flow out from the special discharge port. The screened material is then passed through the magnetic bar to remove the ferromagnetic impurities mixed in the material. The magnetically selected material is sucked away by the suction system to remove dust and fine impurities, and is brought out by the dragon and the air shut.
Clean up equipment
The prefabricated steel silo is referred to as the assembly silo. It is a kind of steel silo formed by punching a corrugated plate by mechanical rolling and molding, and then assembling it through a high-strength bolt connection with an electric torque wrench. The wall plate of the assembly silo is corrugated, and the plate is generally made of galvanized plate, whose thickness is usually 0.8 to 4.2mm, and the thickness of the silo wall can reach 8.4 mm. Most of the corrugated wall panels use the rolling process, which is mass-produced by a mechanical forming production line. The production line can automatically produce corrugated plates of various specifications. The advantages of the rolling method are that the wave shape is formed successively, the internal stress can be eliminated, the resilience is small, and the quality of the produced plate is better. Even thicker steel plates can be formed in sequence on the forming unit assembly line. In addition, the forming unit and supporting equipment such as uncoiler, leveling machine, conveying roller table and hydraulic fixed-length flying shear can directly process the coil into corrugated steel plate products with required specifications.
