The angle of the corner and the number of revolutions are the factors that affect the jaw crusher.

Jaw crusher is the mainstream crushing equipment in the current crushing production line, so the price, quality and efficiency of the jaw crusher have been widely concerned by the mineral industry. In the production process, which are the main factors affecting the efficiency of the jaw crusher? Undoubtedly the angle and number of revolutions of the crusher.

The angle of the joint is the angle between the moving jaw and the fixed jaw. In actual use, it is less than 25 degrees, generally about 18-20 degrees. According to the calculation of the maximum angle of reach up to 32 degrees. Therefore, in order to ensure the granularity of the product, it is fair to enlarge the discharge port as much as possible. The size of the discharge port can be adjusted by adjusting the block. Pay attention to the relationship between the crush ratio and the yield when adjusting the size of the discharge port. If the angle of the teeth is too large, the ore in the crushing chamber will be squeezed upwards, causing injury or damage to other equipment, and at the same time, the increase in the angle of the teeth (increased crushing ratio) decreases. Adjusting the size of the discharge port changes the size of the angle. In the actual life, the size of the discharge port is adjusted according to the requirements of the size of the ore discharge.

If the rotation speed is too large, the ore that has been broken in the crushing chamber will not be discharged, and the clogging phenomenon will occur, which will reduce the production capacity and increase the electric energy consumption. Therefore, the jaw crusher should have a most suitable number of revolutions. Within a certain range, increasing the number of revolutions of the eccentric shaft can improve the production capacity of the crusher, but it also increases the electrical energy consumption of the crushed unit weight ore. The eccentric shaft, connecting rod, movable jaw, shaft and lining of the jaw crusher are the main wear parts, so you need to pay attention to lubrication and replacement.
