Jaw Crusher Brief Introduction

Jaw crusher is mainly used as coarse crusher and medium crusher in mining, building materials, infrastructure and other sectors. According to the width of the feed port, it is divided into three types: large, medium and small. The feed port width greater than 600MM is a large machine, the feed port width between 300 and 600MM is a medium machine, and the feed port width less than 300MM is a minicomputer. Jaw crusher has the advantages of simple structure, easy manufacture and reliable operation.

The working part of the jaw crusher is two jaw plates, one is the fixed jaw plate (fixed jaw), vertical (or the upper end slightly extroverted) fixed on the front wall of the body, the other is the movable jaw plate (movable jaw), the position is inclined, and the fixed jaw plate to form a small crushing cavity (working cavity). The movable jaw plate moves periodically against the fixed jaw plate, sometimes moving apart, sometimes moving closer. When separated, the material enters the crushing chamber, and the finished product is discharged from the lower part; When approached, the material between the two jaw plates is squeezed, bent and split.
Jaw crusher according to the different swing mode of movable jaw plate, it can be divided into simple swing jaw crusher (simple swing jaw crusher). Complex swing jaw crusher (compound pendulum jaw crusher) and comprehensive swing jaw crusher three kinds.
