Rubbing type grain crusher has the advantages of compact structure, small occupation area, simple installation process, less grinding, fine granularity, low energy consumption, low noise, large production capacity, fineness easy to adjust, no dust pollution, easy maintenance and reliable operation and so on. During the silicon thermal method magnesium smelting process, the granularity of ferrosilicon with large rigid is crushed to 3~5mm from 25~40mm. Meanwhile, the device can be widely used in metallurgical, construction, road construction, chemical industry, which is suitable to hard and hard minerals such as iron ore, copper ore, limestone, quartz stone, granite, sandstone crushing, providing the output of perfect granular material. Equipment fully meet customer demand, and the main technology, economic indicators reach the international advanced level.

The performance characteristics are as followings: 

1. Simple and reasonable structure , easy installation;
2. Large crushing ratio, less than 150mm feeding size and less than 6mm discharge particle size;
3. With fine particle size products, cube size, uniform & great particles size ( mainly from 3-5mm), low needle plate and powder content;
4. Low power consumption; The energy consumption is 1.4kw/t.
5. Strong anti-wear ability of tooth plate and easy maintenance.
6.High crushing efficiency, energy saving, low operation and maintenance;
7. Suitable for coarse grinding and fine grinding of medium hard and high hard material;
8. Great adaptability of working environment and wide application;
9. Convenient fineness adjustment and the use of screw jack adjustment;
10. Below 75db of working noise.
