PF Impact Crusher
Thousands of PF series impact crusher are installed all over the world in recent 20 years. It has been proved that this series of pf impact crusher not only effectively increase productivity and final product quality, but also greatly reduce the investment costs and operation costs. Unmatched excellent performance is shown in the secondary crushing, tertiary crushing and material recovery. By absorbing the advanced technology from the world, we researched and designed PF series impact crusher. It can be used to deal with materials whose size below 500mm and whose compression strength less than 360Mpa.
PF Impact Crusher Appilation
PF Impact crusher adopting the latest manufacturing technology and unique structure design, the PF series impact crusher can produce cubic products with very good grain shape without tension and crack. The pf impact crusher consists of an encased rotor carrying swing hammers, whizzer classifier for fineness regulation, and Blower Fan mounted on a solid shaft. Raw material to be pulverised enters the crushing chamber through the hopper and automatic rotary feeder. The impact of the hammer on the feed material against the Liner plates reduces it into fine powder. The ground material is carried towards the whizzer classifier for classification and the over size particles are rejected by the classifier and returns to the crushing chamber for further grinding. The classified material is then conveyed into the cyclone for collection and bagging. A dust collector is provided in the system for ensuring dust Free operation and no loss of ground powder. Thus, it is widely used in many industries, like chemical, metallurgy, road and bridge construction and sand making and so on. Impact crusher has large crushing ratio, simple and rational structure, steady operation, simple maintenance, fast replacement and high crushing efficiency, and can be widely used in industries such as building materials, ore dressing, chemistry and electricity for crushing material with medium hardness and rigidity.
PF Impact Crusher Advantages
Compare to other crushers, our impact crusher has bigger reduction ratio and can fully use the high speed impact energy of entire rotor. But because the impact crusher board hammer is extremely easy to wear, it also is restricted in the hard material stave application. Impact crusher is usually used to break thick garrulous, the limestone, the coal, the calcium carbide, the quartz, the dolomite, the curing iron ore, the gypsum and the industrial chemicals which are hard following brittle material. Impact crusher mainly consists of rotor, impact plate, main shaft, blow bar, impact rack, etc. During operation the raw material will be crushed three times,the first time is crushed by rotor rack with high speed-moving of rotor and material will be through to impact plate,then material will be crushed through the impact force by impact plate,the last crushing force is the squeeze between material when material is flow down to blow bar. This process is repeated only when the material is crushed as required. The size and shape of finished material can be controlled by adjusted the gap between the impact plate and rotor.
