Double-drum roller crusher

Double-drum roller crusher is a tunable crushing equipment suitable for brittle materials with medium hardness or below, such as coal, coal gangue, coke, slag, shale, chemical raw materials, limestone, feldspar, nickel ore, iron ore, and other materials.

The double-tooth roller crusher is an efficient, energy-saving, environmentally friendly, and safe crushing equipment with advantages such as a large crushing ratio, no requirements for the moisture content of the material, non-sticky and non-clogging operation, low over-fining, low noise, low vibration, low dust, low power consumption, small footprint, easy maintenance, and adjustable particle size of the discharge material.

The double tooth roller crusher consists of a frame, working roller, adjusting device, driving device, and protective device, etc. The working roller is divided into a fixed roller and a movable roller. The fixed roller is securely fastened to a rigid frame with bolts, while the movable roller is mounted on a slide track with an adjusting device at the rear, which allows for easy adjustment of the roller gap according to the required particle size.

The double-toothed roller crusher's working rollers rotate in opposite directions through a differential action, powered by two motors via V-belts, featuring mutual scrubbing and automatic cleaning. As materials continuously enter between the rollers, those meeting the particle size requirements fall automatically, while materials larger than the gap are subjected to combined crushing in the form of compression, splitting, scrubbing, and impact in both axial and radial directions. This results in minimal over-fine material, significantly reducing energy consumption.
