Use: this machine changes the existing structure of grinders and integrates the body and bottom frame. It can be placed on the fundamental surface once for all. Main axle adopts double-row self-aligning ball bearing which can reduce energy consumption by 30% and improve granularity. The stirring volume can be increased by 15-20%.
