A Brief Description of the PS and PA-type Crusher
The crusher is the equipment which use one or several methods to make large piece of material broken into small pieces through certain institutions. It is a general equipment widely used in industrial production. According to their works, the process characteristics and structure, the crusher can be divided into the swing crusher (such as jaw crusher), spin tilting crusher (such as gyratory crusher, cone crusher, dual-chamber rotary crushers, etc.), roll crusher (crusher roll crusher, high pressure rolls crusher) and shock (such as hammer crusher, impact crusher, and cage-shaped crusher) and other types. (1) the characteristics of PEWS type (referred to Ps) the outside moving jaw crusher . its fixed jaw is placed between the movable jaw and the eccentric shaft, the crushing chamber is tilted arranged, the fixed jaw is on the upper part, while the movable jaw is on the below part, they constitute the crushing chamber together. And divided into two from top to bottom, two of the movable jaw and fixed jaw have different inclination, the previous paragraph for the coarse crushing, the following paragraph for crushing so that the broken ratio increased up to 13. In addition, the movable jaw lining the lower part along the direction of the discharge opening with a long strip of mesh to constitute the screening board. And supported by the outside Pendulum rode, the moving jaw mainly driven by the eccentric shaft through the side panels for reciprocating motion, positive stroke crushing materials, negative stroke screening. Crushing and screening both operating on the same device, to reduce the clogging of the crusher and had crushed, the energy saving effect is good.
(2) PEWA type (referred to as PA) the outside moving jaw low jaw crusher. The crusher consider the four-bar linkage rod as the crusher side plate while the moving jaw is only the rod extension of connecting rod, deliver the power to the movable jaw through the side plate. The separation of fixed jaw and the rod make the rod no longer be constrained , as long as we change the institutions parameters, you can adjust the trajectory of moving jaw, so the movable jaw can get a good motion characteristics. the cyclical swing of Moving jaw make the Fall broken material be squeezed, crushed, spitted and bended. The crusher's maximum feed particle size is750 mm, crushing capacity is 90-340 m3 / h, Motor power is110 kW, machine hanging is 50l. Production practice shows that the performance is good , stable and reliable.the equipment operation rate is 97%. This crusher's exterior is low, compared with the same type of re-pendulum jaw crusher,its height reduces 25.6% .
