Sand making machine is suitable for crushing soft, medium hard and extremely hard materials. Sand making machine is widely used in many sectors such as large smelting, building materials, highways, railways, water conservancy and chemical industries.
The material enters the sand making machine from the feed hopper and is divided into two parts through the distributor. One part enters the high-speed rotating impeller from the middle of the distributor and is rapidly accelerated in the impeller. The acceleration can reach hundreds of times the acceleration of gravity. It is ejected from the three uniform flow channels of the impeller at a speed of m/s. It is first impacted and broken by a part of the material falling from the surroundings of the distributor, and then hits the material lining in the scroll cavity together and is rebounded obliquely by the material lining. The material that impacts upward to the top of the whirl chamber changes its direction of movement and deflects downward to form a continuous material curtain from the impeller flow channel. In this way, a piece of material will be hit, rubbed, grinded and crushed twice or even multiple times in the whirling crushing cavity. The crushed materials are discharged from the lower discharge port. During the entire crushing process, the materials impact and crush each other on their own, without direct contact with metal components. Instead, they are crushed by impact friction with the material lining, which reduces corner contamination and prolongs mechanical wear time. The clever self-circulation of air flow inside the vortex chamber eliminates dust pollution.
