Description

Technical Field

[0001] The invention relates to the technical field of crushers, and in particular to a centrifugal toothed disc crusher. Background Art

[0002] Centrifugal crushers are widely used in sand and gravel production lines, metallurgy, coal mining, mineral processing, building materials and other industries. Traditional centrifugal crushers have a rotor that rotates at high speed with a vertical axis as the center. The crushed materials put into this rotor are discharged at high speed from multiple discharge ports opened around the rotor under the action of the centrifugal force generated by the rotation of the rotor, and then collide with the material lining formed in the crushing chamber around the rotor to be crushed into fine particles. In order to improve the crushing efficiency, fixed throwing hammers are protruding around the rotor. The crushing principle is that the crushed materials discharged from the discharge port of the rotor collide with the throwing hammer and then crushed. The throwing hammer is fixed to the outer edge of the rotor. Existing centrifugal crushers still have problems such as low compressive strength of crushed materials and large and uneven particle size of discharged materials. Summary of the invention

[0003] The present invention aims to solve the problems existing in the prior art and provides a centrifugal toothed disc crusher. The partition blocks and the material-driving plates on the movable turntable make the materials evenly distributed, and at the same time make the materials rotate with the movable turntable. The fixed crushing teeth and the movable crushing teeth realize material crushing under the rotation of the main shaft and the centrifugal force. The fixed crushing teeth decrease in height from the inside to the outside along the radial direction of the fixed cone disc, and the movable turntable is provided with rotating crushing teeth with decreasing height from the inside to the outside along the radial direction, so that the materials are crushed step by step to the required particle size. The present invention has the advantages of large compressive strength of the crushed materials, small discharging particle size and uniform discharging.

The power part is connected to the pulley through the connecting part. The power part drives the main shaft to rotate. The movable turntable rotates with the main shaft. At the same time, under the action of centrifugal force, the material moves to the outer edge of the movable turntable, and is sheared by the movable crushing teeth on the movable turntable and the fixed crushing teeth extending downward on the fixed cone. The movable crushing teeth of the crusher show a downward trend from the inside to the outside, and the fixed crushing teeth on the fixed cone also show a downward trend from the inside to the outside. In the crushing chamber, the more the material moves outward under the action of centrifugal force, the smaller the activity space is, and it is crushed step by step to the required particle size. According to the requirements of the discharge particle size, the height and tooth spacing of the outermost movable crushing teeth of the movable turntable are controlled to ensure that all the materials that can be discharged from all gaps are materials of qualified particle size, so as to achieve the purpose of stable discharge and controllable particle size.
