The large double-roll crusher is a key piece of equipment for fine crushing operations in industries such as mining and building materials. Relying on the static pressure crushing principle and stable performance, it has become the preferred choice for large-scale production. Its core structure consists of two groups of relatively rotating rollers. Materials fall into the roller gap from the top feed inlet, break along the cracks under the action of extrusion and shearing forces. Qualified particle size materials are discharged directly. While oversized particles are repeatedly rolled until they meet the standards. Equipped with a hydraulic system, the roller gap can be adjusted, and the discharge particle size can be controlled within the range of 0-5mm to meet diverse production needs.

The equipment adopts a heavy-duty cast steel frame and wear-resistant alloy roller skins, with a single-machine processing capacity of 200-400 tons per hour, and can be adapted to medium-hard materials such as river pebbles, limestone, and construction solid waste. It also has the advantages of low consumption and environmental protection, with low vibration and noise. The sealed structure reduces dust leakage, complying with green production standards. The hydraulic overload protection system can automatically retreat from foreign objects, avoiding equipment damage and extending the continuous operation time.

Nowadays, it is widely used in scenarios such as sand and gravel aggregates and solid waste resource utilization. Helping commercial concrete mixing stations and infrastructure projects improve quality and efficiency. After intelligent upgrading, it integrates remote monitoring and automatic lubrication functions. Further reducing operation and maintenance costs, and has become the core equipment to promote the energy-saving transformation of the industry.
