AI Technical Summary

Technical Problem

Traditional coated sand crushing equipment separates the crushing and screening functions, lacking an integrated solution. This results in increased equipment footprint, low production efficiency, and difficulty in effectively handling coated sand blocks of different hardness and structure.

Method used

A crushing device was designed, which combines a screening box and a feeding box. It adopts a power transmission method that combines a motor and a drive assembly. Combined with the design of a guide rod and a top plate, it can achieve precise movement of the crushing head. The crushing head is driven by a hydraulic cylinder, and the crushing gap is adjusted by a combination of a moving block and an electric push rod, so as to achieve integrated crushing and screening.

Benefits of technology

It improves processing efficiency and site utilization, ensures stable rotation speed of the pressure roller under high load, achieves precise pressure control and flexible adjustment of crushing gap, has strong adaptability, and improves the adaptability and processing efficiency of the equipment.
