Jaw Crusher Product Introduction

Jaw crusher, commonly known as jaw breaker, is the primary coarse crushing equipment in sand and gravel production lines and ore crushing processes. It crushes materials through the squeezing action between the moving jaw and fixed jaw. It is suitable for coarse crushing of various ores and rocks with compressive strength ≤ 320 MPa. It is often matched with cone crushers, impact crushers and sand making machines to form a complete crushing production line. It is a classic and widely used crushing equipment in the mining and aggregate industry.

Working Principle

The motor drives the eccentric shaft to rotate via the pulley, which pushes the moving jaw to perform periodic reciprocating swing. When the moving jaw approaches the fixed jaw, materials inside the V-shaped crushing chamber are crushed by squeezing, splitting and bending force. When the moving jaw leaves the fixed jaw, qualified materials are discharged from the bottom discharge opening under gravity. Oversized lumps stay in the chamber for further squeezing and crushing. The discharge opening size is adjustable to control the finished product size.

Pr

oduct Advantages

✅ Robust & Durable Structure Thickened frame and high-manganese steel jaw plates feature strong impact resistance and high wear resistance, suitable for feeding large hard rocks with long service life.

✅ Large Reduction Ratio & Uniform Discharge Large feeding size, stable crushing capacity and well-shaped finished aggregates.

✅ Stable & Reliable Operation Optimized design of core transmission components, strong load capacity and low failure rate.

✅ Easy Maintenance Quick disassembly and replacement of wear parts, simple lubrication system and low operation & maintenance cost.

✅ Wide Compatibility Stationary and mobile models are available. It can work independently or be integrated into large-scale production lines.

✅ Flexible Adjustment Adjustable discharge gap to quickly switch different output sizes to meet diverse requirements.

Applicable Materials

Granite, basalt, limestone, river pebble, iron ore, quartz stone, marble, bluestone, construction waste, coal and other medium & high hardness ores and stones.

Application Fields

Sand and aggregate plants, mining, construction waste recycling, concrete batching plants, infrastructure projects, highway & railway, water conservancy, metallurgy, building materials and other industries for primary crushing.

Main Model Introduction

Two mainstream series: PE Series (Standard Jaw Crusher) 그리고 PEX Series (Fine Jaw Crusher)

• PE Series: Designed for primary coarse crushing, large feed opening for big raw stones as the first-stage crusher.
• PEX Series: Produces finer output, usually used for secondary medium & fine crushing. A full range of models from small 200×300 to large 1200×1500 are available. Capacity ranges from several tons per hour up to over one thousand tons per hour. Customization is supported.

Notes

Model selection should be determined based on material hardness, maximum feed size, required capacity and finished particle size. Proper matching with feeder, conveyor and secondary crushing equipment helps achieve high efficiency and stable production of the whole line.
