Raymond mill jaw crusher is one of the important equipment, in Raymond's production process plays an important role, save manpower, reduce labor costs, welcomed by customers. Meanwhile jaw crusher (jaw broken) is widely used in mining, metallurgy, building materials, roads, railways, water conservancy and chemical and other industries. Compressive strength of not more than 320Mpa can be broken materials, sub-coarse and fine breaking two. The product specification is complete, the feed particle size of 125mm ~ 750mm, is the first choice for primary crushing equipment. 
 Jaw Crusher Operating Environment: 

 In the huge stones broken into small stones in the process of the first crusher is usually referred to as the "main" breaker. Is also the longest history, the most robust crusher. Feed for the broken jaw, the material from the top of the entrance into the room with a broken jaw teeth. Jaw teeth with great force to the top of the wall material will break into the smaller stones. Support E is an eccentric tooth movement axis, this axis runs through the body structure. Eccentric exercise is usually fixed to the shaft at both ends of the flywheel generated. Flywheel and eccentric support bearing is frequently used in spherical roller bearings, bearing the working environment is extremely harsh. Bearings must withstand tremendous impact load, abrasive and high temperature water. Although this work environment is extremely harsh, broken jaw still need to work very reliably, which is to ensure production efficiency a key element. 

 Jaw Crusher Working Principle: 

 The structure of jaw crusher main frame, eccentric shaft, a large pulley, flywheel, moving jaw, side guard, elbow board, elbow board seat, adjust gap screw, spring reset, fixed jaw jaw and other components and activities , which bracket also play a role as insurance. The series of jaw crusher way for music moving extrusion type, motor-driven belt and pulley, the eccentric shaft to move jaw up and down movement, increase when moving jaw plate and movable jaw when the elbow angle between the larger, thus promoting the movable jaw close to the fixed jaw plate, while the material is squeezed, rubbing, grinding, such as multiple broken; when the movable jaw down, the elbow angle between the plate and moving jaw smaller, movable jaw plate in the bar, leave the action of the spring fixed jaw plate, this time under the broken material from the crushing chamber discharge port, with the mobile jaw crusher motor for continuous rotation of the crushing and nesting periodicity to achieve mass production. 

 Jaw Crusher Features: 

 1. Crushing chamber depth and no dead zone, increased feed capacity and output; 

 2 The broken jaw broken ratio, even granularity; 

 3. Gasketed nesting population adjustment device, reliable and convenient, adjustable range, increasing the flexibility of the equipment; 

 4. Lubrication system safe, reliable, easy to replace parts, maintenance workload is small; 

 5 The jaw-breaking structure is simple, reliable, low operating costs. 

 6 energy-saving equipment: stand-alone energy-saving 15% to 30%, more than double the energy system; 

 7 The jaw crusher discharge opening adjustment range, to meet different user requirements; 

 8 The jaw crusher, low noise, less dust.
