1. Overview

　　Suitable for crushing hard materials l compressive strength < 250!, a_ such as: iron ore. For example, the crushing of large blocks in various concentrators, the crushing of large blocks in stone plants, and the crushing of large blocks in limestone in cement plants have the characteristics of large crushing ratio, low maintenance cost, low power consumption, and reliable performance. It can be widely used in mining, stone factory, building materials, metallurgy, ceramics and other industries.

2. Working principle

　　When starting up, the motor drives the belt and pulley. The moving a moves up and down through the eccentric shaft. When the moving 9 rises, the angle between the plate and the moving collar becomes larger, which pushes the moving jaw plate to approach the fixed a plate and at the same time the material is crushed or split. The purpose of crushing is achieved: when the moving 17 goes down, the angle between the separate plate and the moving a becomes smaller. The moving 17 plate is under the action of the pull rod and the spring. When it leaves the fixed a plate, the broken material is discharged from the lower opening of the crushing cavity. The motor continuously rotates and the crushing motor U works in a cycle to crush the materials into ideal particles and discharge them from the discharge port.
