Concrete crushers, also known as double-roll crushers, utilize two motors to drive two sets of rollers that compress and grind materials. The crushed output demonstrates superior performance compared to conventional crushing machinery, capable of processing various rock materials with compressive strengths below 160 MPa. These crushers feature low maintenance costs, minimal water consumption, stable performance, low power consumption, reduced dust generation, and low noise levels. The surging demand for sand and gravel aggregates has driven the growth of artificial sand production. Utilizing concrete crushers for sand manufacturing enables the production of finished products in different specifications and sizes, meeting market requirements.

Concrete Crusher

1.Concrete Crusher

Application Scope:
Suitable for crushing in mining, cement, highway, railway, coal, metallurgy, building materials, and other industries.

2.Working Principle

The concrete crusher utilizes two independently driven roller shafts that rotate in opposite directions to generate crushing and grinding forces. Material enters through the feed opening and falls between the rollers, where it is crushed by the opposing rollers before naturally discharging. When encountering excessively hard or uncrushable material, the rollers automatically retract via hydraulic cylinders or springs, increasing the gap between them. allowing the hard or uncrushable material to pass through unharmed. The opposing rollers can adjust the pressure of the hydraulic cylinders or springs to control the final product’s particle size.

3.Performance Advantages

1. High Crushing Ratio and Strong Production Capacity
Utilizing the compression crushing principle, it achieves a high crushing ratio and is suitable for coarse, medium, and fine crushing of high-hardness materials such as coal, limestone, and slag. The machine operates smoothly with robust production capacity.

2. More Crushing, Less Grinding with Excellent Product Shape
By reducing feed particle size and improving the pulverization characteristics of feed material, it achieves the effect of more crushing and less grinding, enhancing production efficiency. The finished product is fine and of high quality.

3. Long service life and low operating costs
The roller shells are made of high-yield wear-resistant materials, featuring strong impact resistance and high wear resistance. Material loss during crushing is minimal, with low failure rates. This reduces subsequent maintenance and upkeep costs, resulting in low operating expenses and a long service life.
