The advantage of jaw crusher in crushing equipment
working principle of jaw crusher: the motor drives the belt and pulley, and makes the moving jaw move up and down through the eccentric shaft. When the moving jaw rises, the included angle between the elbow plate and the moving jaw becomes larger, so as to push the moving jaw plate close to the fixed jaw plate, and at the same time, the material is crushed or chopped to achieve the purpose of crushing; When the movable jaw goes down, the included angle between the elbow plate and the movable jaw becomes smaller, and the movable jaw plate leaves the fixed jaw plate under the action of the pull rod and spring. At this time, the crushed materials are discharged from the lower opening of the crushing chamber. With the continuous rotation of the motor, the crusher can crush and discharge materials periodically to realize mass production
jaw crusher appeared in 1858 when more than manufacturers called to inquire about relevant equipment. Although it is an ancient ore crushing equipment that suddenly stopped working, it is still widely used in gold smelting mountain, building materials, chemical industry, railway and other departments because of its simple structure, reliable operation, easy manufacturing, convenient maintenance and other advantages. In mines, it is mostly used for coarse crushing and medium crushing of hard or medium hard ores
the performance advantages of jaw crusher are shown in the following aspects:
1 The crushing cavity is deep and there is no dead zone, and nylon and polyester are also used as raw materials to improve the feeding capacity and output; Its crushing ratio is large and the product particle size is uniform
2. The gasket type discharge port adjustment device is reliable and convenient, with a large adjustment range, which increases the flexibility of the equipment
3. The lubrication system is safe and reliable, the parts are easy to replace, and the maintenance workload is small; Simple structure, reliable operation and low operation cost
4. Equipment section 3. There shall be no transverse crack energy at the joint: the energy saving of a single machine is 15% - 30%, and the energy saving of the system is more than twice; The adjustment range of discharge port is large, which can meet the requirements of different users; Low noise and less dust
the jaw crusher adopts hydraulic safety device, which is safe and easy to eliminate faults. Large and medium-sized crushers generally adopt sliding bearings cast with Babbitt alloy, which can withstand large impact loads and are relatively wear-resistant. The small jaw crusher uses multi-purpose rolling bearings, which has high transmission efficiency and convenient maintenance
