PF Series Impact Crusher is one kind of equipment to crushing the brittle material which compression strength no more than 350 Map, the advantage including high crushing ratio, uniform product grain and low over crushing, low energy consumption, high adjustment range of product grain size and optional crushing etc, which is mainly used in mine, metallurgy, cement, construction material, coal etc for secondary crushing and fine crushing the medium hardness material. Application: Metallurgy, construction material, mine, beneficiation and large block material crushing. Our advantages: 1. Large feeding port and high crushing cavity, suitable to crushing the material with high hardness and big grain size, and less powder. 2. The gap between impact plate and hammer plate is adjustable, so the discharging grain size can be effective control and the grain shape is well. 3. The hammer, impact plate and lining plate are made of new type abrasion-proof material with long working life and impact protection, wear protection. 4. Because of the function of three-stage crushing and plastic, so the crushing ratio is high, and the product shape is cube and can optional crushing. 5. The multi-function hydraulic station has many function of hydraulic discharge gap with high speed, impact plate stable vibration and the body open automatically. The PF series impact crusher is mainly compose of the rack, driving system, rotor, hammer and impact plate etc. The main feature including: 1.Rack: It composed by two parts of upper and lower with connection by bolt. All the parts contact the crushed material in the rack have set replaceable lining plate. 2. Driving System: The main shaft and rotor are driving by motor through belt then doing the high speed rotary motion. 3. Rotor: It adopts entire cast steel structure with high mass force, solid and durable, convenient to install the hammer. 4. Impact Plate: It is made from new type abrasion material and hanging freely inside the equipment. One end connect with the two sides of the rack through hanging shaft hinge, another end is bearing in the upper rack cone gasket through stay bolt which is adopt a sphere gasket, it can prevent the equipment damage by non-crushing material when crushing material. 5. Hammer: It is made from new type abrasion material and fixed on the rotor through wedge block
