Factors affecting the power of a jaw crusher

Jaw crusher power is based on the work done by the crushing force in the direction of displacement of the points on the tooth surface during the crushing stroke of a working cycle. The following technical experts will briefly analyze the factors affecting the power of the jaw crusher.

1. The physical and mechanical properties of the material. This is a factor that has a great influence on the power of jaw crusher, including the hardness, compressive strength, humidity and viscosity of the material. If the hardness or compressive strength of the material is high, then the crusher has to do more work to complete the crushing operation, so the power is higher.

2. Specification size. The larger the size of the crusher, the greater the power consumption.

3. Jaw crusher speed. Generally speaking, the higher the rotational speed of the crusher, the larger the mechanical size, the greater the power consumption; the larger the crushing ratio, the greater the power consumption.

4. Eccentric shaft speed. Within a certain range, the eccentric shaft speed increases, the power of jaw crusher will increase accordingly. When the swing of the movable jaw exceeds a certain limit, the power consumption will rise rapidly when the speed is increased again. The high eccentric shaft speed makes the crushed material too late to be discharged from the discharge port, which will cause the energy consumption instead.

5. Crushing particle size. Crushing particle size will also have a certain degree of impact on the power. In the production operation, if the user requires a smaller crushing size, the power of the jaw crusher will be increased accordingly.
