Working Principle of the Sand Maker
The materials falling to the Sand Making Machine are divided into two parts by the distributor, with one part getting into the high-speed rotating impellers through the distributor, which are accelerated quickly in the impellers, reaching 100 times the acceleration of gravity, and then cast at the speed of 60 to 70 m/s from the three distributed passageways of the impellers and impacted by the materials falling around the distributor. Then they are impacted together with the lining in the cavity. Rebounded by the lining, those materials are sent obliquely upward to the top of the vortex cavity, and then they change the direction with a downward deflection, making a continuous material curtain. Therefore, the materials are impacted and crushed constantly in the vortex cavity. The crushed materials are discharged from the bottom port forming a closed circuit with the screening system. Generally, three times circulation can reach the granularity of 20 meshes. During the whole process, the materials are mutually impacted instead of contacting with the metal components, thus reducing the pollution and abrasion of the machine. Moreover, the self circulation of the air in the vortex cavity eliminates dust pollution. Features

This machine is the newly developed equipment in the 1990s for medium and fine crushing, which is also widely used one for replacing cone crushing machines, roller machines and ball mills.

1. Novel and unique structure, smooth operation
2. Low energy consumption, high productivity, high crushing ratio 3. Small size, simple operation, easy installation and maintenance 4. Cubic shape and bulk density
5. Protection layer, no abrasion, durability
6. Hard wear-resisting materials, small volume, light weight, convenient replacement

Classification
