Jaw crusher is commonly known as jaw crusher, also known as tiger mouth. The crushing cavity is composed of two jaw plates, the movable jaw and the static jaw, which simulate the movement of the two jaws of animals to complete the material crushing operation. It is widely used in the crushing of various ores and bulk materials in mining smelting, building materials, roads, railways, water conservancy and chemical industries. It is mainly used as a coarse crusher. The jaw crusher is simple in structure, easy to manufacture and reliable in operation. As a best-selling equipment, jaw crushers are of certain importance in the stone crushing production line.
When the jaw crusher is working, the movable jaw plate reciprocates periodically against the fixed jaw plate, sometimes approaching and sometimes leaving. When approaching, the material is squeezed, split, and impacted between the two jaws and crushed; when leaving, the crushed material is discharged from the discharge port by gravity.
Advantages of BTMA best-selling PE series jaw crusher:
1. Simple mechanism, deep crushing cavity, small nibble angle, large stroke, large processing capacity, low energy consumption and better crushing performance. Coupled with the large inclination bracket design, the lower stroke of the cavity is larger and the output is higher.
2. The design of “big size bearing” is adopted to make it have a large bearing capacity, a longer service life, and safer and more reliable use.
3. The heavy-duty movable jaw assembly adopts forged heavy-duty eccentric shaft, high-quality heavy-duty rolling bearing, and FEM analysis-optimized movable jaw body, which ensures the impact resistance and high stability of the movable jaw assembly; the labyrinth seal and centralized lubrication system guarantee The bearing grease is not polluted, and the lubrication is more convenient, so that the running time is longer and the stability is better.
4. The mechanical or hydraulic discharge opening adjustment device is adopted, and the double wedge adjustment method is simpler, safer and faster than the shim adjustment operation, saving downtime.
5. The jaw plate can choose different tooth shapes according to the different crushed materials to make the crushing effect better. In order to improve the wear resistance of the jaw plate, a heavy-duty guard plate is installed above the movable jaw to avoid the impact of materials and effectively protect the movable jaw. and its internal bearings are not damaged.
6. The integral cast steel bearing seat structure ensures full cooperation with the machine frame, avoiding unnecessary radial load on the bearing during the fastening process of the combined bearing seat, and making the bearing run more smoothly.
7. The integrated installation method of the motor base and the crusher frame not only saves the installation space of the jaw crusher, but also reduces the length of the V-belt. The adjustment of the tension of the V-belt is realized, so that the service life of the V-belt is longer.
