The cement crusher, also known as a double-roll crusher, employs two motors to drive two sets of rollers that compress and grind materials. It delivers superior crushing results compared to conventional crushing machinery, capable of processing various rock materials with compressive strengths below 160 MPa. This equipment features low maintenance costs, minimal water consumption, stable performance, low power consumption, reduced dust generation, and low noise levels.
Cement Crusher
1.Cement Crusher
Feed Size: 25-100mm

Application Scope:
Suitable for crushing in mining, cement, highway, railway, coal, metallurgy, building materials, and other industries.
2. Working Principle
The cement 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. This mechanism safeguards the machine from damage. The feed size of the final product is controlled by adjusting the pressure of the hydraulic cylinders or springs governing the opposing rollers.
3. Performance Advantages
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.
Less Grinding, Better 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.
Long Service Life, 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.
