Mini Jaw Crusher

Mini Jaw Crusher

Materials:
It crushes materials with compressive strength below 320MPa, such as shale, limestone, quartz, construction waste, concrete, ceramics, gypsum, coal, and ore samples.

Scope of application:
It is widely used in laboratories, small mines, material testing, demolition sites, chemical pretreatment, ceramic processing, and small to medium production lines.

Introduction

The mini jaw crusher features a compact structure and flexible mobility, specifically designed for medium to low-volume crushing requirements. Utilizing proven crushing technology, it offers easy operation, low energy consumption, and convenient maintenance. Suitable for laboratory research, small-scale production, and mobile operations, it achieves a capacity of up to 30 tons per hour. The equipment supports dual power options with both electric motor and diesel engine drives and is available in both stationary and mobile configurations.

WORKING PRINCIPLE

After entering the crushing chamber formed by the fixed jaw plate and the movable jaw plate, the material is subjected to extrusion, splitting, and bending by the movable jaw plate, which is driven by the eccentric shaft to perform periodic reciprocating motion. Once crushed to the desired particle size, the material is discharged through the bottom outlet.

Advantages

1. 1.Compact and portable: Easy to transport and deploy in tight spaces or mobile sites.

2. 2.Energy-saving and simple to operate: Runs efficiently with low power use and intuitive controls.

3. 3.Low-maintenance and versatile: Compatible with electric or diesel power, with easy parts replacement for flexible installation.

Parameter

Note: The capacity may vary with different materials and feeding sizes.

FAQ

A small jaw crusher crushes material through periodic compression between two jaw plates (moving and fixed). An electric motor drives the eccentric shaft, causing the moving jaw to swing back and forth. As it moves toward the fixed jaw, material is crushed, split, and ground. When it moves away, crushed material is discharged by gravity from the outlet.
A small jaw crusher has a simple, compact design, so most daily maintenance (like lubrication and tightening) can be handled by the user. It has few core components, and replacing main wear parts is easy. Simply check the discharge opening gap, repair the adjustment device, tighten the liners, and replace worn jaw plates and toggle plates regularly.
To extend the service life of a small jaw crusher: control feed size and hardness, ensure continuous and uniform feeding, remove impurities before feeding, use the symmetrical jaw plate design, install jaw plates offset, keep plates tightly against the frame, maintain sufficient lubrication, regularly check sealing and dust prevention, and tighten bolts routinely.
A small jaw crusher is used for crushing medium-hard to hard materials with compressive strength up to 320 MPa, such as granite, basalt, feldspar, river stone, and marble. It is widely applied in mining, metallurgy, construction, roads, railways, water conservancy, and chemical industries.
