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. When the working principle and operation of these precautions crusher motor pulley driven by eccentric shaft rotation, so that the jaw cycle to close, leaving the fixed jaw, thereby materials are extrusion, rub, grind, such as multiple broken, so that the material from big 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 crusher, then relax bolt the top wire to obtain the desired size of the discharge opening, the nesting population adjustment range is 5-30mm. (2) feeding adjustment device: the upper part of the machine is provided with a hopper, between which is provided with a 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 Ways crusher equipment, 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. Hammer crusher impact crusher with crushing ratio, high production capacity, uniform particle size and other characteristics, the crusher is metallurgy, building materials, chemicals and utilities and other industrial sectors crushing limestone, coal or other medium hardness less brittle materials one of the main equipment. Hammer crusher is the use of high-speed impact of hammerhead role of materials broken machinery broken and minor operations. Hammerhead hinged on the high-speed rotation of the rotor cone crusher, the lower part of the body to control the grate nesting size. Material into the crusher by high-speed movement of the first impact of the initial hammerhead broken, and access to energy at the same time, high speed toward the inner wall of the chassis and broken plate again been broken. Less than grate gap material is discharged outside the machine, more than grate gap slug impact on the grate and grind hammer again, until less than grate of the gap after being discharged.
