The stone material falls directly from the upper part of the machine into a high-speed rotating turntable. Under the action of high-speed centrifugal force, it produces high-speed impact and high-density communication. After the stones hit each other, they will form a vortex motion between the turntable and the casing. Repeatedly hit each other, rubbing, crushing, and crushed into the required size.The development of a new type of medium and fine crushing equipment is widely used in the world to replace the cone crusher, roller mill, and ball mill. The structure is novel, unique and operates smoothly. With plastic function, and the product is set up square shape, high packing density, in the production process, the stone can form a protective bottom layer, the body does not wear and durable. A small amount of easy-to-wear parts are made of special hard-wearing materials, which are small in size and light in weight, making it easy to replace parts. The rotor disc of the box crusher is
