Double Roller Crusher

The Double Roller Crusher is widely used in coal mining, mineral processing, and cement industries for its reliable performance and adjustable output size. With models including 2PG400×250, 2PG610×400, and 2PG1000×800, it offers high crushing efficiency, overload protection, and easy maintenance. By optimizing roller speed and gap settings, it ensures uniform particle size distribution while minimizing energy consumption, making it ideal for secondary and tertiary crushing applications.

The Double Roller Crusher is a fundamental crushing equipment in mining, coal preparation, and cement industries. Designed for medium-hard and brittle materials such as coal, limestone, and slag, it achieves precise size reduction through compressive forces between counter-rotating rolls. Featuring adjustable roll gap (2-10mm), this crusher produces uniform 5-30mm particles ideal for secondary crushing and raw material preparation. Its compact structure and low dust generation make it particularly suitable for confined spaces and environmentally sensitive operations.

When selecting models, key considerations include material characteristics (2PG610×400 for coal, 2PG800×600 for limestone) and production requirements (including overload protection and dust containment systems). Future developments will focus on wear-resistant roll surfaces and automated gap adjustment to further improve crushing efficiency and reduce maintenance downtime in continuous operation scenarios.
