Impact crusher, also known as sand making machine, vertical impact crusher by feeding, distributor, vortex dynamic crushing cavity, experience the impeller, spindle assembly, base drive device and electric motors is composed of seven parts. 

SBMs impact crusher is widely used in all kinds of metal and non-metallic minerals, cement, refractories, abrasive, glass raw materials, building aggregate, mechanism sand, metallurgy and other industries. Suitable for crushing different hardness of various minerals and rocks, such as iron ore, non-ferrous metal ore, carborundum, bauxite, quartz sand, corundum, perlite, basalt in high hardness materials finely homework is the core equipment in the domestic construction, mining, metallurgy industry and highways, railways, bridges, water and electricity, mineral grinding area and the mechanism of sand industry. 

Impact crusher in terms of its working principle, a simple point is that the principle of stone stone. Let the stone in the natural fall process and through the impeller to speed up the stone thrown out of the collision, so as to achieve the purpose of breaking. And was accelerated by the fall of the stone and natural stones fall into a vortex, the return process and the two broken, so in the process of running the machine on the impact of the board is very little. 

Stone from the top of the machine directly into the high-speed rotation of the turntable, in under the action of centrifugal force, and another part of the umbrella type shunt in the wheel around the target of stone produce high speed impact and high density of crushing, stone in the fight against each other, will between the turntable and the chassis in the formation of vortex motion caused by repeatedly against each other, friction, grinding, direct discharge from the bottom. To form a closed circuit, the size of the required particle size is controlled by the screening equipment. 

Performance characteristics 

1. the structure is novel, unique, running balance. 

2. the energy consumption is small, the output is high, the crushing ratio is big. 

3. The equipment is small in size, easy to operate, convenient to install and maintain. 

4. with shaping function, the product is cubic, bulk density. 

5. the production process, stone can form the protection of the bottom, the body no wear, durable. 

6. a small amount of easy to wear parts with special hard wear resistant material, small size, light weight, easy to replace parts.  

Technical characteristics 

1. high crushing efficiency, has finely, coarse grinding function; 

2. the structure is simple, the installation, maintenance is convenient, the operation cost is low; 

3. through the non crushing material ability is strong, the material moisture content influence is small, the water content is up to 8%; 

4. the product grain shape is excellent, cube, needle plate content is extremely low, suitable aggregate shaping, artificial sand making and high grade highway aggregate production; 

5. product bulk density, iron pollution is very small.
