Principles of the cone crusher

Principles of the spring cone crusher

In the working process of the spring cone crusher, the motor drives the eccentric sleeve to rotate through the transmission device. The moving cone swings under the force of the eccentric sleeve. The section near the static cone becomes the crushing chamber. The material is crushed by the multiple extrusion and impact of the moving cone and the static cone. When the moving cone leaves this section, the material that has broken to the required size falls under its own gravity and is discharged from the bottom of the cone.

Principles of the hydraulic cone crusher

The crushing process of the hydraulic cone crusher is completed between the fixed fixed cone and the rotary moving cone. When the crusher works, the horizontal axis of the crusher is driven by the motor through the triangular belt and the pulley. The horizontal axis rotates the eccentric sleeve by the big and small gears. The eccentric distance of the cone shaft of the crusher is generated by the eccentric sleeve to make the surface of the crushing wall close to each other. The fixed cone surface is sometimes far away from the fixed cone surface, so that the stone is continuously crushed, broken and impacted in the crushing chamber. The crushed material is discharged from the discharge outlet of the lower part of the crusher under the action of self-weight.

Principles of compound cone crusher

When the compound cone crusher works, the upper cavity of the moving cone is supported on the spherical bearing bush at the end of the fixed spindle, and the lower cavity sleeve is outside the eccentric shaft sleeve, and its motion is directly driven by the eccentric shaft sleeve. When the eccentric sleeve rotates around the spindle, the moving cone not only rotates around the center line of the machine, but also around its own axis. The moving cone rotates around its spherical support center in space. The axis of the moving cone intersects the center line of the spindle at a fixed point, that is, the center point of the sphere, and its angle is the procession angle. When the crusher runs, the axis of the moving cone moves in a conical direction relative to the center line of the machine, and the cone top is the spherical supporting center. The point remains stationary during the moving process 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 consists of two kinds of rotational motion: procession motion or involution motion (the rotational motion of the moving cone around the center line of the machine) and rotation motion or relative motion (the rotational motion of the moving cone around its axis).

Principles of the moving cone crusher

When the crushed material moves in the crushing chamber, it stays for several seconds and bears about 30 times of force from the crushing body. In each moving cycle, the material particles change their orientation with the adjacent particles, resulting in continuous changes in the force vector. These particles can achieve the alternating stress of crushed materials and cause forced self-crushing conditions. Particles with fewer structural defects have higher strength and can crush adjacent particles with weak inter-granular connections. In equip-strength particles, the particles whose shear force and dislocation sliding direction coincide with each other break up. The shattering cone oscillates at least 100 times a week, which is caused by the non-uniformity of its rolling along the material layer and accelerates the shattering due to the supplementary impulse force.

Principles of the multi-cylinder cone crusher

Multi-cylinder cone crusher is a new energy-saving fine crushing equipment with unique principle and structure, which can realize selective crushing of materials and meet the requirements of the new technology of "more crushing and less grinding". The machine not only has large crushing ratio, fine and uniform product size, low power consumption per unit, but also has low grinding body consumption and low iron pollution. It can crush brittle materials with any hardness. It is very suitable for the crushing of non-metallic ores. In this paper, the working principle and structural characteristics of inertial cone crusher are briefly described, and the wide application prospect of inertial cone crusher in non-metallic mineral processing is proved by examples.

Principles of high efficiency cone crusher

This type of stress can occur when the cone crusher works with high efficiency due to the result of alternating pulse stress. At this time, the important condition is that the frequency and deformation speed of these stresses should be high enough. In high-efficiency crusher, when the hardness of material and the filling rate of crushing chamber change, the value of crushing force is essentially unchanged. It is related to the debugging of crusher, that is, to the static moment and rotational speed of the selected unbalanced body. Adjusting the static moment of the unbalanced body can determine the breaking force required under any working conditions. Changing the crushing force can ensure the compactness of the material layer, make the particles bear all-round load, and break most of them according to grain boundaries, basically creating conditions for obtaining crystal shape products under the condition of less slime production. However, if the selected crushing force exceeds the strength limit of the connection between the particles of a given material, it will lead to over-crushing and local extrusion of the product at the outlet of the crushing chamber.

Principles of the single cylinder cone crusher

When the single cylinder cone crusher works, the rotation of the motor moves around a fixed rotary pendulum through the pulley or coupling, transmission shaft and cone under the force of eccentric sleeve, so that the crushed wall of the single cylinder cone crusher sometimes approaches and sometimes leaves the surface of the rolled white wall fixed on the adjusting sleeve, so that the ore is continuously impacted, extruded and bent in the crushing chamber to realize the broken ore. When the non-breakable foreign body passes through the crushing chamber or the machine is overloaded for some reason, the spring insurance system realizes the insurance, the ore discharge outlet enlarges, and the foreign body is discharged from the crushing chamber. If the foreign body is stuck in the ore discharging chamber, the cavity cleaning system can be used, so that the ore discharge continues to increase and the foreign body can be discharged from the crushing chamber. Under the action of spring, the discharging outlet is automatically reset and the machine resumes normal operation.
