impact crusher

SBM PF impact crusher (sales code: PF) is a new product by absorbing advanced technologies from home and abroad. The impact crusher is ideal choice for crushing and screening. The most outstanding advantage of this impact crusher is that its finished power is in good, cubic shape and without tensility and cranny. So the final products of the impact crusher is ideal used in highway and railway surface as well as water and electricity industry.

Impact crusher is usually used as the secondary crusher machine in stone production line. Before the impact crusher, jaw crusher has crush the larger stones, rocks, ores to small enough which is suitable for the impact crusher.
PF series impact crusher is suitable for crushing stones, rocks, ores whose size is smaller than 500 mm and pressure resistance strength is under 320Mpa. This kind stone crusher can process your hardest and most difficult materials greatly reducing the typical risk of stoppages, damages and high maintenance associated with most other jaw crushers. This powerful high capacity plant will crush your competition.

SBM impact crusher is optimized and widely applied in the primary and secondary crushing process. This impact crusher is applicable for various coarse, medium, fine materials( such as granite, limestone, concrete, basalt, bluestone etc.), whose grain size not exceeding 500mm and compression strength not higher than 360Mpa. SBM impact crusher is widely applied in mining and construction, transportation, energy and chemical industry.

This stone crusher is characterized by great reduction ratio, high reduction efficiency and convenient maintenance, etc.

1) The hammer of the impact crusher is made of high chromium cast iron.
2) Impact liner plate is made of wearable materials.
3) The impact crusher is with unique structure, keyless connection.
4) The impact crusher is more suitable for crushing hard rock with environmental protection and high efficiency.
5) Final product of the impact crusher is in the shape of a cube; the discharge grain size is adjustable to simplify the crushing circuit.
6) Easy maintenance and reliable performance.
7) Hydraulic or hand opening ,either way is possible

Impact crusher parts are: real case, impact plate, impact rack, scale board, feed opening, chassis, blow bar, rotor.

SBM impact crusher use the impact energy to break rock or other materials. When the impact crusher works, the motor drives the rotor where the plate hammers fixed rotate with high speed.The raw materials are crushed in the crushing cavity.And the high-speed rotating rotor casts the crushed materials along tangential direction to impact plate at the other end of the crushing cavity.

When the materials enter blow bar area, they are crushed due to the high-speed impact of the blow bar and are throw to the impact plates on the rotor for secondary crush. Then the materials will be shot back to the blow bar again for the third crush. This process repeats until the materials are crushed to the required size and discharged from the lower part of the machine. The size and shape of the finished powder can be changed by adjusting the gap between the impact rack and rotor support. The machine employs self-weigh security device in its back frame. When other objects enter the impact cavity, they will be forced out of the machine by the impact rack in the front and back of the machine.

The materials are bumping with each other when being sent between the plate hammer and the impact plate. The materials become cracked, loose and then comminuted by knocking by the plate hammer, impact with impact plate and bump between materials. The materials with grain size smaller than the gap between impact plate and plate hammer will be discharged.
