Jaw crusher, primary crushing device of choice, with a crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics, it is widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry and many other sectors.
Jaw crusher machine is the use of compression and bending two jaw plates for materials, rough broken or broken various hardness materials broken machinery. Its broken body from the fixed jaw plate and movable jaw plates, near the time when the two materials Jibei jaw broken jaw when the two left the nesting population is less than a block of material discharged from the bottom. Its crushing action is carried out intermittently. This crusher machine due to simple structure, reliable and able to crush hard materials, etc. are widely used in mineral processing, building materials, silicate and ceramics and other industrial sectors, and cone crusher machine compared to less investment jaw crusher machine finished stone tablets, low production costs. Compared with the hammer crusher machine wear parts to use for a long time, high efficiency, small post-investment.
To the 1980s, 800 tons of material per hour crushing large jaw crusher machine feed size has reached about 1800 mm. Commonly used jaw crusher machine has two elbows plates and single brackets. The former moving jaw at work only for simple swing arc, so called simple swing jaw crusher machine; the latter, while the swing arc is still up and down movement, so called complex swing jaw crusher machine. Jaw crusher machine is widely used in crushing compression strength not exceeding 320 MPa of various materials.
Jaw crusher machine works: the huge stones broken into small stones during the first crusher machine is usually referred to as "master" crusher machine. The oldest and most robust crusher machine is jaw crusher machine. When the jaw crusher machine feed for the material from the top of the entrance into the crushing chamber containing the jaw teeth. E tooth with great force to the top of the wall material, will it be broken into smaller stones. Support E tooth movement is an eccentric shaft, the shaft through the body frame. Eccentric motion is usually fixed at both ends of the shaft of the flywheel generated. Flywheel and eccentric support bearings are often used spherical roller bearings, bearing the working environment is very harsh. Bearings must withstand tremendous impact loads, abrasive and high temperature water. Although this work environment is very harsh, jaw crusher machine still very reliably, which is to ensure the productivity of a key ring.
