Pf Hydraulic Stone Impact Crusher

We are offering pf hydraulic stone impact crusher.
(1) introduction:
pf series impact crusher is a new product that absorbs advanced technologies at home and abroad. This series equipment can crush material which max feed size is less than 500mm; compression strength is not more than 320 mpa (e.g.: granite, limestone, concrete etc.) with its excellent performance and good performance, impact crusher is widely used in highway, hydroelectric, artificial stone and sand, crushing and building material industry etc.
pf series impact crusher has larger crushing ratio, and can make full use of the high-speed impacting energy of the entire rotor. However, due to the blow bar is easily to wear, so it is restricted in hard materials. So impact crusher is mainly used in coarse, medium, and fine crush, such as, limestone, coal, calcium carbide, quartz, dolomite, sulfuration iron ore, gypsum, chemical raw material etc., under medium hard brittle material.
(2) working principle:
the blow bar of rotor shaft is revolved by an electric motor through v-belts, and crushing the feeding material,then the crushed material can be thrown to the impact plate,and crushed again,then return to the bars and be crushed for another time. This process will be repeated for several times until the material up to required graininess. The material from the feed opening goes into the first crushing chamber,then the second crushing chamber, lastly, the size of the stone is less than the gap between the blow bar and the impact plate and is discharged from the lower part of machine that is what you want.
(3) features and benefits:
1 many cavity 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.
