Jaw crusher mainly consists of frame, supporting device, the working mechanism (fixed jaw plate and moving jaw plate), drive mechanism (eccentric connecting rod, thrust plate, flywheel and eccentric shaft), safety device and adjusting device of ore discharging port (wedge adjustment device, gasket adjustment device). The working parts of jaw crushers are two jaw plates. The first one is the fixed jaw plate (fixed jaw), vertically (or the upper end slightly camber) fixed in front of body wall, and the other mobile jaw plate(moving jaw) is located tilt and connected with fixed jaw to form the next upper big and lower small crushing chamber (working chamber). The mobile jaw plate moves towards the fixed jaw plate to do periodic reciprocating motion, sometimes separately and sometimes closely. During the Separation, the material going into the crushing chamber and the finished product is discharged from the lower port; when they are closed, the material is squeezed between the two jaw plates and broken by bending and splitting.

Hxjq is a coal jaw crusher supplier from china, we manufacturer the professional jaw crusher for coal mine. We are one of the largest crusher manufacturers in China, so you choose us to cooperation and you will get lots of profit.

Coal jaw crusher could be the initial choice for Stone crusher plant; Essential jaw crusher is extensively utilized in mining, metallurgy, setting up supplies, streets, railways, drinking water conservancy and chemical sectors, and so forth. Jaw Crusher is actually a sort of Stone crusher, and jaw crusher is additionally identified as Rock crusher. This collection of Jaw crusher for coal mine have several benefits which mostly used in breaking a spread of ore as well as medium-size chunk of supplies. The compression power from the resources to generally be crushed is below 320MPA. it can be divided into coarse crusher and fine crusher. We have all specification varieties of the solutions, and its feedstock size is 125mm-750mm. We also offerjaw crusher parts. To a service-oriented brand integrity, as the professional manufacturer of complete sets of mining machinery,

Coal jaw crusher is greatly employed in mining, metallurgy, development, highway, railroad, and chemistry sectors and and so forth. Several products of jaw crusher are offered according to your distinct fineness specifications. The jaw crusher for coal mine contains a aspect of big crushing ratio, for example uniform completed item measurement, simple framework, major reduction ratio,trustworthy procedure, straightforward maintenance, decreased operation value. The best anti-pressure power of crushed material is 320MPa.

If the crushing ratio is unchanged, the decrease of the meshing angle will increase the swinging stroke of the movable of the structure of jaw crusher. According to the test, the single piece of material is crushed. The materials are split in half along the fore-and-aft plane of the action of the extrusion pressure. Sufficient amount of compression must be given to the material. The ration of the amount compression to the original longitudinal dimension of the ore is called the relative amount of compression. In the crushing cavity, the actual amount of compression imposed on the materials and the swinging stoke of the movable of the jaw crusher is equal. In the operation of the single toggle jaw crusher, the swinging stroke of the movable jaw decreases gradually from bottom to top, while the size of the materials to be crushed become larger and larger. If the swinging stroke of the upper part of the movable jaw is enough, the swinging stroke of the lower part of the movable jaw can be well met. According to the test, the swinging stroke of the upper part of the movable jaw should be more than 0.005D. For the compound pendulum jaw crusher, the swinging stroke of the lower part of the movable jaw must be less than (0.3 to 0.4) e. The swinging stroke of the upper part of the movable jaw is about 1.5 times as the swinging stroke of the lower part of the movable jaw.
