 Jaw crusher (jaw crusher) referred to the broken jaw, also known as Tiger, gravel machinery and equipment is most commonly used. Jaw crusher (jaw crusher) first appeared in 1858, the first widely used in road construction, and later used in mining, is now available for a variety of ores and medium-grained bulk materials broken, broken, that the maximum The compressive strength of 320MPa. It also has a big crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. Which medium-sized jaw crusher (jaw crusher) is the company leading products, in the absolute position in the domestic leading level. According to the particle size after crushing, the jaw crusher (jaw crusher) can be divided into two kinds of coarse and fine broken. Widely used in many industries of mining, smelting, building material, highway, railway, water conservancy and chemical industry. 
 Performance characteristics 
 A crushing chamber depth and no dead zone, improve the capacity and output of the feed; 
 Its broken than large, uniform particle size; 
 Gasket type discharge opening adjustment device, reliable and convenient adjustment range and increase the flexibility of the device; 
 (4) the safety of the lubrication system is reliable, easy to replace parts, maintenance workload; 
 Simple structure, reliable operation and low operating costs. 
 6. Energy-saving equipment: stand-alone energy-saving 15% to 30%, the system energy efficiency more than doubled; 
 7 nesting population adjustment range to meet the requirements of different users; 
 Low noise, less dust; 
 Working principle 
 Main rack in the structure of the jaw crusher (jaw crusher), the eccentric shaft, pulley, flywheel, moving jaw, side guard, elbow board, elbow boards rear seat, adjust gap screw, reset spring, fixed jaw activities Hubei board, which bracket also play a role in insurance. 
 PE series jaw crusher (jaw crusher) broken the way for the song moving extrusion type, motor-driven belt and pulley, the eccentric shaft to move the jaw up and down movement when moving jaw increases the toggle plate and moving angle between the change in Hubei between thus promoting the fixed jaw plate close to the fixed jaw plate, at the same time the material is squeezed, rub, grind multiple broken; when moving jaw downstream angle between toggle plate and moving jaw, move the jaw in the rod under the action of the spring away from fixed jaw crushed material discharged from the crushing chamber mouth, continuous rotation with the motor broken motor Hubei periodically crushed and nesting, and mass production. www.yhzg.org
