Working principle of cone crusher

During the working process of the cone crusher, the motor drives the eccentric sleeve to rotate through the transmission device, and the moving cone rotates and swings under the force of the eccentric sleeve. The static cone is broken by multiple squeezing and impact. When the moving cone leaves this section, the materials that have been crushed to the required particle size fall down under the action of their own gravity and are discharged from the bottom of the cone.

Cone Crusher

The crushing process of the cone crusher is completed between the fixed fixed cone and the rotating moving cone. When the cone crusher is working, the horizontal shaft of the crusher is driven by the motor through the V-belt and the pulley, and the horizontal shaft drives the eccentric sleeve to rotate through the large and small gears. , so that the surface of the crushing wall is sometimes close to the surface of the fixed cone, and sometimes away from the surface of the fixed cone, so that the stone is continuously crushed, broken and impacted in the crushing cavity. The crushed material is discharged from the discharge port at the lower part of the crusher under the action of its own weight. The upper cavity of the cone crusher is supported on the spherical bearing bush at the upper end of the fixed main shaft, and the lower cavity is sleeved on the outside of the eccentric sleeve, and its movement is directly driven by the eccentric sleeve. When the eccentric bushing rotates around the main shaft, the moving cone not only rotates around the center line of the machine with the eccentric bushing, but also rotates around its own axis. The moving cone performs a space swing movement around its spherical support center. The axis of the moving cone and the center line of the main shaft intersect at a fixed point, that is, the center point of the spherical surface, and the included angle is the precession angle. When the cone crusher is running, the axis of the moving cone moves on a conical surface relative to the center line of the machine, and the top of the cone is the spherical support center, which always remains stationary during the movement of the moving cone. Therefore, the motion of the moving cone can be regarded as the rotation of a rigid body around a fixed point, that is, the motion of the moving cone is composed of two kinds of rotational motions: precession motion or implicated motion (the moving cone rotates around the center line of the machine) and rotational motion or relative motion. Movement (rotating movement of the moving cone around its own axis).

In the case of no-load operation of the cone crusher, the rotation of the moving cone is determined by the friction torque given by the spherical bearing to the moving cone and the frictional force given by the eccentric bushing to the moving cone. direction turn. Under normal circumstances, the moving cone rotates along the rotation direction of the eccentric sleeve, and the rotation speed is determined by the difference between the two torques. And this type of cone crusher is between the spherical bearing and the lower bushing of the moving cone to control the rotation of the moving cone. In the case of loaded operation, the friction torque of the stone on the cone surface of the moving cone far exceeds the friction torque generated by the eccentric bushing on the moving cone.

As long as you press a button, there will be a display on the console, and you can see the size of the discharge port that needs to be adjusted, which is very convenient and accurate.

Cone Crusher

When the machine is working, the motor drives the large bevel gear at the bottom of the eccentric sleeve through the hydraulic coupling and the small bevel gear, so that the eccentric sleeve rotates, causing the cone to swing and crush the material. The main shaft of the crusher is not moving, but only supports the spherical tile to bear the crushing force. Because the main shaft of the crusher does not move and the eccentric sleeve transmits the crushing force, the structure can withstand a large crushing force, and is very suitable for fine crushing and ultra-fine crushing, because the crushing force of ultra-fine crushing is very large. It is estimated that the product particle size (for ultrafine crushed liner) can reach 50^80% (depending on the nature of the material) when the circuit is opened. The crusher is suitable for the third stage crushing or the fourth stage crushing of metal mine concentrators; it is suitable for building materials or non-metallic mines and civil engineering. Especially in areas where the supply of natural sand required for civil engineering is insufficient.
