In operation, electrical motor of impact crusher drives the rotors to rotate at high speed. And as the hammers were installed on the rotors, so when the raw material was fed into the impact crusher, the rocks or ores will be crushed by the hammers under the impact function of hammers which rotate at high speed. And then the broken rocks were rebounded to the liner plates for secondary crushing. This processing will continue until the required product size is discharged from the discharge outlet of the impact crusher.
SBM coal impact crusher is mostly used in the secondary crushing processing. The crusher is especially built for medium hard rocks and stones which compression strength is less than 350Mpa and max, such as limestone, dolomite, sandstone, marble, barite, bluestone, construction demolished debris, etc. Feeding size is less than 500mm. Due to its cubic shaped final product. Impact crusher is widely used in sand making plant, highway and railway surface as well as water conservancy industries.
1. High-chromium plate hammer, unique Impact plate, especially for hard rock crushing, high efficiency and energy saving.
2. Low and big feed opening make the production line easy to arrange and increase the size of feeding material.
3. Many cavities to crush, suitable for crushing hard rock.
4. New anti-abrasive material which prolong service life of impact hammer, impact plate and liner.
5. Hard stone crushing, high efficiency and energy saving.
SBM coal production line is used in mineral dressing, chemical industry, cement, building materials, fire-proof materials, ceramics, glass and other industries, for crushing medium hardness ore, such as limestone, quicklime, chamotte, slag, calcium salt, clay mine, building materials, coke, coal and other materials which the compressive strength does not surpass 150MPa and the moisture is less than 10%.
