AI Technical Summary

Technical Problem

In existing jaw crushers, the jaw plates wear out severely during the feeding process because the ore falls in a parabolic manner, resulting in an unsatisfactory buffering effect and gaps that prevent the material from being effectively buffered.

Method used

A guide plate, a fixed frame, a buffer plate, a buffer strip, a support plate, a buffer spring, and an inclined plate are installed inside the feed inlet to form a triple buffer structure. The guide plate provides initial buffering, while the inclined plate and the buffer plate, together with the buffer spring, provide elastic support to achieve efficient buffering.

Benefits of technology

It effectively reduces the impact force of materials on the jaw plate, extends the service life of the jaw plate, and improves the mechanical stability and crushing efficiency of the crusher.
