When the equipment is working, the material falls vertically from the upper part of the machine into the high-speed rotating oneimpellerInternally, under the action of high-speed centrifugal force, it collides and crushes at high speed with another part of the material that is divided in an umbrella shape around the impeller. After colliding with each other, the materials will form vortices between the impeller and the casing and collide and rub against each other multiple times to crush them. They will be discharged directly from the lower part, forming a closed loop for multiple cycles, and controlled by screening equipment to achieve the required particle size of the finished product.
