Type: Secondary Crushing Input Size: 400mm--1520mm Processed Materials: Limestone, Granite, Gabbro, Basalt, River Stone, Coal Gangue, Quartz, Diabase, Iron Ore, Copper Ore, Zinc Ore, Manganese Ore, etc. Applications: Aggregates Shaping, Mechanism sand, Bituminous Concrete, Metal Mine, Sand Making, Chemical, Road, Railway Capacity: 30-250TPH Impact Crusher,By adopting the developed technology and unique structural design, finished products processed by impact crusher boasts cubic shape without tension and cracks. It can crush stone smaller than 500mm with compression strength lower than 350MPA, such as granite, limestone, concrete, etc. Impact crusher is widely used in all kinds of ore crushing, railway, highway, energy, cement, chemical industry, construction, etc. The output size can be adjusted. Impact Crusher Features: 1. Many cavities to crush, suitable for crushing hard rock 2. Reasonable design of leveling plate making charge finer and cubic without interior cracks 3. Low and big feed opening makes the production line easy to arrange and increase the size of feeding material 4. Use the hydraulic to open, easy to maintain and change wear-parts 5. New anti-abrasive material makes longer service life of impact bar, impact plate and liner. Impact Crusher Working Principle: Impact crusher crushes material by striking energy. When it works, the motor drives the rotor to rotate at a high speed, on which the blow bar is installed. As soon as the material gets into the affecting area of the blow bar, they will be stroke by the blow bar and be thrown to the impact devices around the rotor. The high speed forces the material to rebound from the impact liner to the area where the blow bar effects until they have been crushed to the required size. The clearance between the impact racks and the rotor can be adjusted to change the size and shape of the end products.China Impact Crusher website:http://www.yrscreen.com/stone-crushing-equipment/impact-crusher/
