Jaw Crusher | XingQing Machinery

Product OverviewProduct Overview

Jaw Crusher is mainly used for medium and primary crushing of various materials with compressive strength not exceeding 320 MPa. Features include large crushing ratio, high output, uniform product particle size, simple structure, reliable operation, easy maintenance, and economical operating costs.

Working PrincipleWorking Principle

1

Feed

The moving jaw retreats, increasing chamber volume, and material feeds into the chamber by gravity.

2

Crushing

The moving jaw advances, compressing and shearing the material between moving and fixed jaw plates, causing fragmentation.

3

Discharge

When crushed material is smaller than the discharge opening, it is automatically discharged from the crushing chamber bottom.

4

Cycle

Each eccentric shaft revolution completes one "feed-crush-discharge" cycle for continuous crushing.

Selection AdviceSelection Advice

Material Hardness：For Mohs hardness 7-8 (granite, basalt), choose PE-600×900 and above models with high manganese steel jaw plates for extended wear life。
Capacity Requirements:For daily capacity under 500 tons, choose PE-400×600 ~ PE-600×900；For thousand-ton production lines, choose PE-900×1200 models and above。
PE vs PEX Selection：PE SeriesSuitable for primary crushing，PEX SeriesSuitable for secondary crushing，Can be combined to form a complete crushing process。
Wet/Sticky Materials：Increase discharge opening or add drying pretreatment to prevent material clogging，Ensure continuous stable production。
