The ore crusher, known as a double-roll crusher, utilizes 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 types 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.

Ore Crusher

1. Ore Crusher

Feed Size: 25-100mm

Production Capacity: 2-400 t/h

Suitable Materials:

Highways, high-speed railways, high-rise buildings, municipal projects, hydroelectric dam construction, concrete mixing plants, sand and gravel yards, etc.

Application Scope:

River pebbles, calcite, quartzite, marble, cobblestones, bentonite, iron ore, bluestone, quarry rock, slag, limestone, weathered sand, diabase, granite, basalt, etc.

2.Working Principle

The ore 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 that regulate 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.

More Crushing, Less Grinding with Excellent Product Shape

By reducing feed particle size and improving the pulverization characteristics of feed material, it achieves greater crushing and less grinding, enhancing production efficiency. The finished product is fine and of high quality.

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.
