SJ multi cylinder hydraulic cone crusher

The working components of the crusher are two cones, one is the moving cone fixed on the main shaft, and the other is a stationary cone that is part of the frame. The centerline of the main spindle cone intersects with the centerline of the fixed cone at a β angle (about 2 °). The lower end of the spindle is inserted into an eccentric bushing, which rotates around the bushing at an eccentric distance, causing the moving cone to perform eccentric swinging motion along the inner surface of the fixed cone. When it approaches the fixed cone, the stone material at that location is crushed by the squeezing, bending, and shearing effects of the moving cone. When it deviates from the fixed cone, the already broken stone material falls to the bottom of the cone due to gravity. As the eccentric bushing continues to rotate, the moving cone also rotates and swings continuously. Therefore, the crushing process and unloading process are carried out continuously along the inner surface of the fixed cone in sequence.

When crushing stone materials, friction is generated on the surface of the moving cone due to the crushing force, which is opposite in direction to the direction of the cone's movement. Therefore, a torque is formed on the main axis, causing the moving cone to rotate in the opposite direction while also rotating around the axis. This self rotating motion can promote a more uniform particle size of the product and also make the wear on the surface of the moving cone uniform.

Stone is crushed by compression, bending, and shearing between two conical surfaces, and can be freely discharged after crushing, resulting in high production capacity and low power consumption.
