subject: Commonly used jaw crusher machine [print this page] Crusher machine is the row size greater than three millimeters compound content of more than 50% of the total emission feeding amount of crushing machinery. Crushing operations often by feeding and nesting into coarse grain size of the broken, broken, and broken bits. Gravel equipment commonly used jaw crusher, jaw crusher, impact crusher, impact crusher, compound crusher, single-stage hammer crusher, vertical crusher, gyratory crusher, cone crusher machine, roll crusher, double roll crusher, combo breaker, forming several broken machines.
Jaw Crusher jaw plates is the use of two compression and bending on the role of materials, rough or broken pieces of various hardness of the material in the crushing machinery. The multi-hammer crusher crusher Structure from the fixed jaw plate and movable jaw plates, jaw plates near the time when the two materials Jibei broken left jaw when the two less than the discharge opening of the material discharged from the bottom block. It's crushing action is carried out intermittently. This crusher due to simple structure, reliable and hard materials can be broken, etc. and is widely used in mineral processing, construction materials, silicate and ceramic industries. Twenty of the 20th century to 80 years, 800 tons of material per hour, a large broken jaw crusher feed size has reached about 1800 mm.
Commonly used jaw crusher machine with elbow board and two single brackets. The former moving jaw at work only for simple circular swing, so called simple swing jaw crusher; the latter also for the arc swing up and down movement, so called swing jaw crusher complex. Jaw Crusher is widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry and many other sectors, not more than 320 MPa breaking strength of various materials. Single mobile jaw crusher toggle plate upper and lower jaw movement to promote the role of nesting, and travel is greater than the upper level of the lower part of bulk materials easily broken, so the broken plate efficiency is higher than your elbows. The disadvantage is that jaw plate wear faster, and the materials have been crushed leaving the phenomenon of increased energy consumption. In order to protect important parts of the machine is not damaged due to overload, often the simple shape, size, smaller board design for the weak link in the elbow, making it the first overload of the machine deformation or fracture. In addition, to meet the size requirements of different discharge and compensation jaw plate wear and tear, but also the addition of discharge opening adjustment device, usually in the seat and rear rack bracket placed in between the pads, or wedge adjustment. But to avoid damage due to replace the broken parts to affect production, but also can be used to achieve the insurance and the hydraulic adjustment device. Some jaw crusher is also directly driven by hydraulic drive movable jaw plate, material crushing action to complete.
