Jaw crusher is mainly used for crushing various large ores and materials. It can crush materials with compressive strength not greater than 350 MPa and diameter not greater than 1200 mm, it is a primary crushing equipment. Large jaw crusher is one of our products, which has reached a high level at home and abroad.
Working principle of jaw crusher:
The working principle of jaw crusher is as follows: the motor drives the belt and pulley to move the movable jaw up and down through the eccentric shaft. When the movable jaw rises, the included angle between the elbow plate and the movable jaw becomes larger, so as to push the movable jaw plate close to the fixed jaw plate, and at the same time, the materials are crushed or split to achieve the purpose of crushing; When the movable jaw descends, 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 jaw makes periodic movement to crush and discharge materials, so as to realize mass production.
Jaw crusher features:
The crushing cavity is deep and has no dead zone, which improves the feeding capacity and output; Its crushing ratio is large and the product particle size is uniform; The gasket type discharge port adjustment device is reliable and convenient, with a large adjustment range, which increases the flexibility of the equipment; The lubrication system is safe and reliable, easy to replace components and small maintenance workload; Simple structure, reliable operation and low operation cost. Equipment energy saving, stand-alone energy saving 15% to 30%, system energy saving more than double; The discharge port has a large adjustment range, which can meet the requirements of different users; Low noise and less dust.
Product advantages:
1. Good grain shape.
During the crushing operation of the equipment, the material blocks form a large upward and downward rolling movement at the lower part of the movable jaw, so that the crushed materials can be easily unloaded in the shape of a cube, reducing the flaky components, and having the characteristics of good particle shape and good product quality.
2. Cost savings.
Because the jaw crusher adopts new and good technology, it can make the crushing parts have more impact force and improve the striking efficiency; Moreover, the structure is compact and simple, and the operation is simple. There is no need for too many workers in the production process, which reduces the labor force of workers and saves certain costs for customers.
3. High production.
Compared with the crushing equipment of the same scale, the jaw crusher not only has lighter weight, fewer components and more compact structure; The crushing chamber is well filled, the loaded material blocks are uniformly crushed, and the finished products are forcibly discharged from the lower end of the movable jaw, so the productivity is higher. Which is 30-45% higher than that of the crushing equipment of the same specification.
4. Good dustproof effect.
All dust collectors of jaw crusher are equipped with dust removal bag device. When dust enters the filter bag, the dust removal bag will expand rapidly in an instant, and shake off the dust with the opposite direction of air flow. The dust attached to the bag surface will quickly leave the filter bag and fall into the ash bin. The dust will be discharged by the ash unloading valve to achieve the purpose of ash removal.
