Double Roll Crusher

Product Overview

Double Roll Crusher is a high efficient and energy-saving medium and fine crushing equipment, which adopts the unique double-roll extrusion crushing principle and is designed for medium-hard and soft materials with compressive strength less than 300MPa. With the advantages of compact structure, easy operation and low maintenance cost, it is widely used in mining, thermoelectricity, cement, ceramics, metallurgy and other industrial fields, and is especially suitable for the crushing operation which needs to control the granularity of the material accurately.

Working Principle

1. Material entry: the raw material enters the V-shaped crushing chamber formed by the gap between the two rolls.

2. Extrusion and crushing:

   • The material is squeezed by the relative rotating roll surface

   • At the same time to withstand the shear and erosion effect

3. Particle size control:

   • Adjusting the roll spacing can precisely control the particle size of the discharged material.

4. Finished product discharge: The crushed material is discharged from the lower discharge port.

Core Advantages
