Purpose of sanding machine (grinder)
This series of sanders (Sanders) are suitable for crushing and shaping soft or medium hard and extremely hard materials. They are widely used in various ores, cement, refractory, bauxite clinker, carborundum, glass raw materials, machine-made building sand, stone and various metallurgical slag, especially for high hard, extra hard and wear-resistant materials such as silicon carbide, emery, sintered bauxite and American sand Higher output crusher.
In the engineering field, it is an ideal production equipment for machine-made sand, cushion material, asphalt concrete and cement concrete aggregate.
In the mining field, it is widely used in the pre grinding process, which can produce a large number of fine ores and reduce the high cost grinding load.
Due to the excellent low wear characteristics of this series of Sanders, the equipment is also used for high abrasion resistance and secondary disintegration crushing production. In addition, due to the zero pollution to the products, the impact crusher is very suitable for the production of glass quartz sand and other high-purity materials. The impact crusher can meet almost any production requirements in the production capacity range of 10-500t / h.

Working principle of sand grinder (sand grinder)
The material enters the grinding machine (sand grinder) from the feeding hopper, and the material is divided into two parts by the distributor. One part enters the high-speed rotating impeller from the middle of the distributor, and is accelerated rapidly in the impeller, and its acceleration can reach hundreds of times of the acceleration of gravity, and then the material is separated into two parts by the distributor The impeller is ejected from the three evenly distributed flow channels. Firstly, it is impacted and broken with a part of the materials collected from the distributor, and then it impacts on the material lining in the vortex branch cavity together. The material lining rebounds and impacts the top of the vortex chamber obliquely. Then it changes its movement direction and deflects downward. The material emitted from the impeller channel forms a continuous material curtain. Such a piece of material is subjected to two or more times of probability impact, friction and grinding crushing in the vortex crushing chamber. The crushed material is discharged from the lower discharge port. In the whole crushing process, the materials impact each other, not directly contact with metal components, but impact and friction with the material lining and crush, which reduces the angular pollution and prolongs the mechanical wear time. The ingenious self circulation of airflow inside the vortex chamber eliminates dust pollution.

Grinding machine (sand grinder) performance characteristics:
Simple structure and low cost;
2. The unique bearing installation and advanced spindle design make the machine have the characteristics of heavy load and high speed rotation.
3. It has the function of fine crushing and rough grinding;
4. High reliability and tight safety protection device to ensure the safety of equipment and personnel;
5. Stable operation, low noise, high efficiency, energy saving and high crushing efficiency;
6. The moisture content of the material has little influence on the moisture content, and the moisture content can reach about 8%;
7. The wearing parts have low loss, and all wearing parts are made of high-quality wear-resistant materials at home and abroad, with long service life. A small number of easy to wear parts are made of special hard wear-resistant materials, small volume, light weight, easy to replace accessories.
8. The air flow in the vortex chamber is self circulating, and the dust pollution is small.
9. The material self-lining in impeller and vortex crushing chamber can greatly reduce the cost of wear parts and maintenance workload. In the production process, the stone can form a protective bottom layer, the fuselage is wear-free and durable.
10. Various installation methods, mobile installation.
11. The product is cubic, with high bulk density and low iron pollution. It can be used for stone shaping by machine.
