It in the cavity of side off the net, is drained on transmission device through third drainage conduit, transmission device passes through the bakelite less than screening criteria partial size
Powder particles are transmitted to extrusion process and are squeezed again, sizing screening, in time collect qualified product, underproof production
Product are transferred into corresponding process in time and are reprocessed, and improve production efficiency；Screen box right side has been connected by hinge cover board,
Cover board can periodically be opened the first vibration screen in screen box and the second vibration screen are replaced or cleaned, facilitate operation；
It is connected between screen box and pedestal by damping spring, during screening, damping spring plays cushioning buffer effect, extends
The service life of equipment, and pedestal lower end is provided with anti-skid bulge, prevents pedestal during screening from sliding, stability
It is high；Total, the present invention has reasonable in design, easy to operate, classification grinding, good crushing effect, crushes uniform and complete, classification
Screening, qualified product collected in time, underproof product is transferred into corresponding process in time and is reprocessed, produced
The advantages of high-efficient and suitable industrialized production.
