Reason Analysis of Low Output of Jaw Crusher

The jaw crusher is driven by a motor. According to the pulley of the motor, the eccentric shaft is driven by the V-belt and the groove wheel, so that the movable jaw moves repeatedly according to the set track, and the material enters the crushing cavity composed of the jaw plate and the side guard plate. According to the closing movement of the movable jaw and the fixed jaw, the materials are squeezed, ground and crushed in the crushing cavity, and the finished raw materials are discharged from the lower discharge port.
 

In the production of jaw crushers, the phenomenon that the production volume does not meet the standard will lead to a decline in production efficiency, and the production volume does not meet the standard. It is not necessarily a problem with the quality of the machine equipment, but it may also be caused by a failure in the production process.

1. The dislocation of the jaw plate and the relative tooth top to the tooth top will also lead to a reduction in the productivity of the jaw crusher. The solution at this time is to check the tooth pitch size of the tooth plate. If it does not meet the standard, the jaw plate needs to be replaced. In addition, the positional relationship between the fixed jaw plate and the movable jaw plate should be adjusted to ensure that the tooth top is fixed and pressed against the tooth root to avoid displacement, so as to ensure the smooth production of the equipment.

2. The discharge port is smaller than the specified limit, so the processed materials cannot be discharged in time, which not only causes a decrease in production capacity, but also easily leads to blockage. The solution at this time is to adjust the discharge port so that it is in the Within the scope specified in the product instruction manual.

3. The wiring of the motor is wrong, and there are three main manifestations: the wiring position of the motor is reversed, the main engine is reversed (the movable jaw rotates clockwise), and the motor is connected in a delta connection into a star connection. These methods all make the jaw crusher It cannot work normally, so its production capacity is reduced. The solution is to adjust the wiring method of the motor.

4. The strength or toughness of the processed material exceeds the requirements of the equipment. This phenomenon refers to the phenomenon that the type of input material exceeds the processing range of the jaw crusher, which increases the difficulty of manufacturing and causes a decrease in production capacity. The solution is to replace it. materials or replace the crusher model.
