Product Details

Heavy-Duty Jaw Crusher for Primary Crushing

The Jaw Crusher is the indispensable primary crushing equipment in mining. It is designed to crush hard rocks with compressive strength up to 320MPa, such as Granite, Basalt, and Limestone.

OreSolution's Jaw Crusher features a Deep Crushing Cavity and Heavy-Duty Forged Eccentric Shaft, ensuring a high crushing ratio (reduction ratio) and reliable operation in the toughest environments.

Working Principle: Squeezing & Crushing

The motor drives the movable jaw plate to move periodically towards the fixed jaw plate, crushing the stone like a giant nutcracker.

Feeding

Large raw boulders (up to 1200mm) are fed into the crushing chamber by a Vibrating Feeder.

Crushing Action

The eccentric shaft drives the Movable Jaw to approach the Fixed Jaw. The material is crushed by squeezing, splitting, and bending.

Discharging

When the movable jaw retreats, the crushed material falls down. If it meets the size requirement, it is discharged to the Cone Crusher.

Jaw Crusher Structure and Working Principle

Technical Choice: PE Series vs. PEX Series

We offer two series of Jaw Crushers to meet different stage requirements:

Feature	PE Series (Primary)	PEX Series (Secondary)
Feed Opening	Large (Deep cavity).	Small & Wide.
Application	Coarse Crushing (First stage).	Fine Crushing (Second stage).
Output Size	Larger (e.g., 100-300mm).	Finer (e.g., 20-60mm).

Core Advantages

1. High Crushing Ratio

Deep crushing cavity design increases the feeding capacity and crushing ratio (up to 6-8).

2. Robust Structure

Integrated cast steel bearing housing and heavy-duty forged eccentric shaft ensure stability under high load.

3. Easy Adjustment

Wedge discharge adjustment system is simpler, safer, and faster than traditional shim adjustment.

Frequently Asked Questions (FAQ)

Q: How long do the Jaw Plates last?

A: It depends on rock hardness. For hard granite, movable jaw plates typically last 3-5 months. We use High Manganese Steel (Mn13Cr2) to extend life.

Q: What if the crusher gets blocked?

A: Our Jaw Crusher is designed with a deep cavity to minimize blockage. If it happens, stop feeding immediately. Never use an iron bar to poke the ore while the machine is running.
