Jaw crusher is mainly used for a variety of ores and bulk materials of medium-grained broken, widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry. Maximum compressive strength of the material to be broken for the 320MPa. Commonly used types of jaw crusher jaw crusher about hundreds of species, but in its very nature, does not exceed the simple movement of the pendulum and compound pendulum two kinds. The former is mostly made of large or medium-sized, crushing ratio of 3-6. The working principle and operation precautions when the crusher jaw crusher motor pulley driven by eccentric shaft rotation, so that the jaw cycle close, leaving the fixed jaw, thereby materials are extrusion, rub, grind, such as multiple broken, so Material from big to small, gradually whereabouts until discharged from the discharge port. As the performance of the machine (negative support zero suspension) limit and the mechanical structure, the design uses a single moving jaw ears mosaic structure, making the machine structure is very compact. (1) Adjust the nesting population: the discharge opening width of the dual-chamber double-acting jaw jaw crusher can be adjusted according to user needs at any time, by adjusting the position of the toggle plate (with two bolts side of the machine to adjust the top wire) to After adjusting gasket on the bracket, then loosen the bolts top wire to obtain the desired size of the discharge opening stone crusher, nesting population adjustment range is 5-30mm. (2) feeding adjustment device: the upper part of the machine is provided with a hopper to the crusher, in which is provided between the feed adjustment bezel. This baffle can be adjusted to the primary crushing chamber side, whose role is to take the plate inclination to control both the quantity of the crushing chamber. (3) return spring: The machine design uses a single moving jaw ears mosaic structure, compared with the traditional crusher is completely different in structure, the return spring is set by its structural limitations, which can only be used at present way, in the middle of the two rear movable jaw to its pre-tensioned tension spring form. (4) Overload: PSSl50X 400 dual-chamber double-acting overload protection design jaw jaw crusher negative reference to the traditional structure of the support jaw crusher, elbow board seat with the frame as a whole, in order to bracket hinge knot machine the frame and movable jaw, acts as overload protection. Composite crusher works material from the crusher vertical centrifugal impeller rotating at high speed, the impact of the height of the surrounding ground and the other impeller material flow in each part of the high-speed impact to other materials, then they will form a vortex impeller and housing several shocks, friction and abrasive material crushing machinery, from the bottom of the composite crusher, a direct closed-loop control emissions by several screening equipment to achieve the required finished size. Use of the composite compound crusher crusher (compound break) is widely used in a variety of ores, cement, refractories, high-hard bauxite, carborundum, glass raw materials, special hard material crushing. In the sand and various metallurgical slag crushing mechanism construction range have higher returns compared to the effectiveness of a wide range of applications, as well as other types of crushers.
