If the quality of crusher components is good, the wear of jaw crusher is small, which has a great impact on the service life of jaw crusher.
During the actual service life of jaw crusher, the discharge outlet shall be adjusted according to the required discharge particle size. Therefore, under the requirements of product size, it is reasonable to expand the discharge outlet as much as possible. The discharge port can be adjusted by the adjusting block, and the correlation between the reduction rate and the production rate should be noted when adjusting the discharge port.
The meshing angle is the angle between the moving jaw and the fixed jaw. According to the calculation, the larger meshing angle can reach 32 degrees. In actual use, it is less than 25 degrees, generally about 18-20 degrees. If the meshing angle is too large, the ore in the crushing chamber will extrude upward, causing injury or damage to other equipment. At the same time, with the increase of the meshing angle (the increase of the crushing ratio), the productivity will decline. Adjusting the size of the ore discharge mouth will also change the size of the meshing angle.
In real life, the size of the ore discharge mouth is adjusted according to the requirements of ore discharge granularity. Therefore, it is reasonable to enlarge the ore discharge mouth as much as possible under the requirement of product size. The size of the ore discharge mouth can be adjusted by adjusting the block. When adjusting the size of the ore discharge mouth, attention should be paid to the relationship between the crushing ratio and the productivity.
In a certain range, increasing the number of revolutions of the eccentric shaft can improve the production capacity of the crusher, but it will also increase the power consumption of crushing the ore per unit weight. If the rotating speed is too high, the crushed ore in the crushing chamber will not be discharged in time, which will lead to blockage. On the contrary, the production capacity will be reduced and the power consumption will be increased. Therefore, the jaw crusher should have a more appropriate number of revolutions.
The discharge port of jaw crusher is related to its productivity, so it should be adjusted according to the discharge granularity. Under the requirements of product size, the discharge outlet shall be reasonably expanded as much as possible. Therefore, the quantity of gravel mining rock shall be controlled, resources shall be centralized and dispersed, and small enterprises shall be encouraged to cooperate with large enterprises to effectively use resources and improve the quality of sand and gravel on the market.
