Overview

Jaw crushers are typically used as primary crushers, or the first step in the process of reducing rock. They typically crush using compression. The rock is dropped between two rigid pieces of metal, one of which then move inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece.

Jaw crusher movement is obtained by using a pivot point located at one end of the “swing jaw”, and an eccentric motion located at the opposite end.

Features

1. High crushing ratio, well-distributed final product size.
2. Discharge opening of the jaw crusher is adjustable reliably within a wide range through the stuffing of shim, thus it can meet various requirements of customers.
3. Lubrication system of it is safe and reliable, which boasts an easy and convenient maintenance.
4. Simple structure, reliable performance, low maintenance cost.
5. Little dust and low noise.

Working Principle

The motor transmits power through belt, drives the moving jaw to do periodic motion towards the fixed jaw by the eccentric shaft. The angle between toggle plate and moving jaw plate increases when moving jaw moves . So the moving jaw moves towards the fixed jaw. The stuff will be crushed in this process. The angle between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw moves leaves fixed jaw by pulling rod and spring, the final crushed stuff will be discharged from the outlet.
