The working principle of sand making machine is that the material falls vertically into the impeller of high-speed rotation from the upper part of the machine. Under the action of high-speed centrifugal force, the material distributes around the impeller in umbrella form with the other part to produce high-speed impact and break up. After the material collides with each other, it will form eddy current between the impeller and the casing and interact with each other many times. The product is crushed by impact and friction, and discharged vertically from the lower part. The required particle size of the product is screened out by screening equipment.
