When working, put the material to be crushed into the machine from the hopper on the side of the machine casing, and rely on the grinding roller device suspended on the plum blossom frame of the main machine to revolve around the vertical axis and at the same time rotate itself. Due to the centrifugal force during rotation, The grinding roller swings outwards and presses tightly on the grinding ring, so that the spatula scoops up the material and sends it between the grinding roller and the grinding ring, and the purpose of crushing the material is achieved due to the rolling and rolling of the grinding roller. Wind separation process: After the material is ground, the fan blows the air into the main casing, blows up the powder, and is sorted by the analyzer placed above the grinding chamber, and the over-fine material falls into the grinding chamber for regrinding. The powder that meets the specifications enters the cyclone collector with the wind flow, and after being collected, it is discharged through the powder outlet, which is the finished product.

The air flow returns to the fan from the return air pipe at the upper end of the large cyclone collector. The air path is circular and flows under negative pressure. The increased air volume of the circulating air path is discharged through the exhaust pipe between the fan and the main engine, and enters the small cyclone collection. device for purification.
