Crusher is currently widely used in many fields equipment, especially in the field of mineral resources as well as the construction sector crushing process , we know crusher is mainly through the interaction of the back plate , linings and rotors to achieve the broken material etc., so the material in the crushing process , the rotor and the back plate is the key to determine the effectiveness of the material crushing , crushing trends feed inlet chamber is getting lower and lower and large, the back plate as much as possible by the second stage , and close to the lower end of the nesting population centers horizontal rotor so as to increase the crushing effect.
Three back plate crusher , impact crusher as Hardopact and PWC-B1314 low rpm three-chamber crusher , domestic 2PF1212 type crusher , crusher with three back plate and PFQ scroll Crusher machines. If the crusher chamber divided by the back plate , back plate corresponding to the first stage of the crushing chamber , said a cavity back plate corresponding to the second stage of the crushing chamber , said second chamber , the back plate corresponding to the third stage of the crushing chamber , said three cavity. So with three back plate crusher crushing due to the increased number of cavities can enhance the selective crushing, grinding of the material increases . Thus , through the addition of the crushing chamber , a rotor rotational speed of the lower taken , not only can achieve a higher rotational speed typically requires in order to achieve the crushing effect , but also cause the product to reduce the particle size is too large and reduces the wear plate hammer . For example , the general two-chamber crusher needs 36 ~ 40 m / s speeds up the crushing speed and processing power, with three chambers ( three back panel ) Crusher only need 22 ~ 30 m / s speed can be. In addition, the material crusher crushing ratio depends primarily on the length of the route back . Counterattack crusher line with...
