Double-roller impact crusher

Abstract

The invention discloses a double-roll impact crusher, which consists of a shell, a feeding hopper, a drive roll, an impact roll and a transmission device, wherein the shell consists of an upper shell and a lower shell; the drive roll and the impact roll which performs reciprocating vibration from left to right are arranged in parallel on split positions in the shell; the lower shell is directly connected with a foundation; and the upper end of the upper shell is connected with the feeding hopper. The double-roll impact crusher is characterized in that the drive roll is supported on a straight shaft; the straight shaft is arranged on a bearing pedestal on both ends, and driven to rotate at a low speed by a motor through a speed reducer; the impact roll is supported by an eccentric shaft of which both ends are arranged on the bearing pedestal, and is arranged on an eccentric part through a pair of bearings; the eccentric shaft is directly driven to rotate at a high speed by the motor; and eccentric blocks are connected with both ends of the eccentric part of the eccentric shaft. The double-roll impact crusher has the advantages of low energy consumption, high efficiency, good crushing effect, simple structure and no vibration on a machine body.

Description

technical field [0001] The invention relates to a double-roller crusher, which belongs to crushing machinery, in particular to a double-roller impact crusher. Background technique [0002] The twin-roller crushers widely used in current production mostly install two crushing rollers side by side in the body, and obtain the opposite rotation of the two crushing rollers through synchronous gears or two electric motors. The crushing of materials is completed by the extrusion of crushing rollers, which requires a large extrusion force, large transmission torque, high power consumption, low crushing efficiency, and the transmission mechanism is relatively large. The double-roll vibrating crusher is proposed to solve the above problems. It uses the principles of vibration, impact and shear to crush materials, with low energy consumption and high efficiency. However, the structure of the double-roller vibrating crusher is complicated, the spring system needs to adjust many paramet...

AI Technical Summary

Problems solved by technology

However, the structure of the double-roller vibrating crusher is complicated, and the spring system needs to adjust many parameters, and the particle size of the output cannot be strictly controlled. At the same time, the machine body itself will generate strong vibration, and a special vibration reduction system is required to reduce the disturbance to the foundation.
