PE, PEX series jaw crusher is a large kind of complex tilting crushing equipment, and it is mainly used for crushing medium hard ore and rock whose compression strength is no more than 250MPa, and with the quality of large crushing ratio, high yield, uniform particle size, reliable, easy to maintain and low operating cost, it is widely used in mining, metallurgy, construction, roads, railways, water conservancy, chemical industry and etc. PE series is used for coarse crushing different kinds of ores and rocks, and PEX series is used for intermediate and fine crushing. Application: Be applied in large block of material crushing in mining industry, metallurgical industry, construction industry, highway, railway, water, and chemical industry. Feature and Advantages: 1.Jaw plates is made of high strength steel, one time shape casting, and with characteristics of wear resistant, compression resistance, and long life; 2. High productivity, large crushing ratio, uniform product size, low power consumption 3. Gasketed discharging adjusting device, reliable and convenient, large adjustment range, equipment flexibility is increased. 4. Simple structure, reliable operation and low operating costs, safe lubrication system, and easy parts replacing. PE, PEX series jaw crusher is mainly consist of frame, eccentric shaft, pulley, side guard plate, bracket, discharging gate adjusting device, fixed jaw plate, movable jaw plate, safety device and etc. And its main structural features are as following: 1Frame It mainly is consist of side panels, front box assembly, rear box, and etc; 2Eccentric Shaft Rotating Part It mainly is consist of movable jaw, eccentric shaft, bearings, bearing pedestal, belt pulleys and etc., and it is the major part for dynamic transmission; 3Crushing Cavity Working Part It mainly is consist of fixed jaw plate, movable jaw plate, side liners, guard board and etc., and it is the working parts for breaking materials; 4Safety Device It is consist of bracket, bracket base, spring, spring rod and etc., and it is the parts that play a security role during crusher works in an abnormal condition. 5Discharging Gate Adjusting Device It is mainly consist of adjusting fixed ramp, adjusting sliding ramp, top wire bolt, slide locking lever, and etc., it is used to adjust the size of the discharging gate and to control the discharging particle size.
