Large jaw crusher is one of the commonly used mining equipment in mining crushing production lines and sand making production lines. It is a new type of fine crushing and coarse grinding product without screen bars, which is adjustable and optimized on the main specifications and parameters based on the comprehensive domestic and foreign advanced fine crushing equipment.
The large jaw crusher can be widely used in the fine crushing of raw materials and clinker in cement plants. It can also be used for medium-hardness dolomite, coke gemstone, lead-zinc ore, serpentine, blast furnace slag, coal gangue, phosphate rock, etc. The fine crushing operation of materials is especially suitable for the processing and crushing of hard limestone, dolomite, granite, basalt and other artificial sand or highway pavement stones. It has the characteristics of large crushing ratio, low energy consumption, stable operation, simple structure, easy operation and maintenance.
Jaw crusher performance characteristics:
1. The large jaw crusher has a deep crushing cavity and no dead space, which improves the feeding capacity and output;
2. Its crushing ratio is large and the product particle size is uniform;
3. The gasket-type discharge port adjustment device is reliable and convenient, with a large adjustment range, which increases the flexibility of the equipment;
4. The lubrication system is safe and reliable, parts replacement is easy, and the maintenance workload is small;
5. Simple structure, reliable operation and low operating cost.
6. Equipment energy saving: a single machine can save 15% to 30% energy, and the system can save more than double the energy;
7. The discharge port has a wide adjustment range and can meet the requirements of different users;
8. Low noise and less dust.
Working principle of large jaw crusher:
The structure of a large jaw crusher mainly includes a frame, eccentric shaft, large pulley, flywheel, movable jaw, side guards, toggle plate, toggle plate rear seat, gap adjustment screw, return spring, fixed jaw plate and movable jaw plate, etc. Composition, in which the bracket also plays an insurance role.
The crushing method of large jaw crusher is curved extrusion type. The motor drives the belt and pulley, and moves the movable jaw up and down through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, thus pushing the movable jaw plate. When the movable jaw moves downward, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw moves away from the fixed jaw under the action of the pull rod and spring. At this time, the crushed material is discharged from the lower opening of the crushing cavity through the jaw plate. As the motor continuously rotates, the movable jaw of the crusher performs periodic crushing and discharge to achieve mass production.
Large jaw crushers are commonly used equipment in mining production lines. Therefore, selecting a good large jaw crusher is a prerequisite for improving mining production.
