AI Technical Summary

Technical Problem

In existing ore crushing devices, the wear condition of the upper and lower halves of the jaw plate differs significantly, and the crushing is not thorough enough, leading to frequent replacements and increased intensity of subsequent crushing work.

Method used

An ore crushing device was designed. Through a detachable jaw plate structure and adjustment components, the crushing plate can be flexibly replaced according to the wear condition. Secondary crushing is achieved by combining the reciprocating motion of the crushing parts. The crushing effect can be controlled by adjusting the distance between the support platform and the crushing parts.

Benefits of technology

It reduces jaw plate replacement costs, improves crushing efficiency, and ensures thorough ore crushing and long-term stable operation of the equipment.

Abstract

This utility model discloses an ore crushing device, relating to the field of ore crushing technology. The utility model includes a crusher body, jaw plates, a drive component, an adjustment assembly, a support platform, and crushing components. The drive component is disposed on the surface of the crusher body, and the jaw plates are disposed inside the crusher body. By loosening the bolts at the sleeve plate, the limiting baffle is released from its position, allowing it to slide inside the sleeve plate and move away from the slide groove. When it is necessary to disassemble a severely damaged crushing plate, it is pushed to slide quickly out of the slide groove. The two sets of crushing plates, one above the other, allow for adjustments based on wear and tear during actual use, reducing the replacement frequency of the upper crushing plate and increasing the replacement frequency of the lower crushing plate, thus reducing jaw plate replacement costs while maintaining crushing efficiency.
