What factors affect the crushing force of the jaw crusher?

The crushing force is one of the main parameters of the jaw crusher. The analysis of the crushing force has important guiding significance for improving the crushing effect of the jaw crusher. To determine the crushing force, it is necessary to analyze the influencing factors of the crushing force of the jaw crusher. We give a brief description:

1. The mode of action on the material. The crushing of rock ore is al* always done by mechanical crushing. The working modes of crushing machinery include crushing, splitting, breaking, grinding and impacting. For hard ore, it should be broken by bending and impact; for brittle ore, bending and splitting are more favorable; for ore with higher toughness and viscosity, it is better to use grinding and stripping. The jaw crusher is mainly crushed, combined with bending, and the difference in the way of action of the material determines the difference in crushing force.

2. The law of movement of the movement of Hubei. The trajectory distribution of each point on the moving jaw is reasonable, and its horizontal stroke gradually decreases from * to bottom along the moving e-plane, which should meet the requirements of increasing the amount of compression when crushing large blocks of material. The lower end of the E will move downwards. The Hengchang heavy industry personnel said that the moving jaw of the jaw crusher is a complex plane motion. The upper trajectory is similar to a circular ellipse. The motion trajectories of the upper points are all elliptical.

3. The nature of the material. The properties of the material include viscosity, hardness, compressive strength, etc. The compressive strength of different materials is different, and the crushing force generated is also different. Therefore, the calculation formula of the crushing force should include the parameters of the mechanical properties of the material. In addition, the particle shape of the material will also affect the crushing force of the jaw crusher.

4. The movement of the tooth plate. When the movable tooth plate moves, the force of the tooth plate is not synchronized in the upper part and the lower part, and it is opposite to each other in some sections, the crushing force generates crushing force, and the discharging stroke does not generate crushing force, so the crushing force in different sections The size is not the same.
Analysis of the influencing factors of the crushing force of the jaw crusher is helpful to establish the calculation formula of the crushing force. It is the basis for calculating the mechanical parameters such as strength and stiffness of the machine components, and is of * significance for ensuring the normal operation and prolonging the service life of the crusher.
