Four-Tooth Roller Coal Crusher – Fast & Efficient Coal Crushing

DESCRIPTION / TECHNICAL SPECIFICATIONS

Optimize your coal production workflow with four-tooth roller technology designed specifically for maximum extrusion and shear force. This equipment utilizes four high-strength wear-resistant rollers working in pairs through an integrated two-stage crushing process. The first stage occurs between the upper two toothed rollers forming a V-shaped crushing cavity for coarse breaking, followed by the lower two rollers that perform fine crushing (choked) to achieve the required particle size.

The primary advantage of this machine lies in its powerful performance, with an output capacity reaching 1000 to 1200 tons per hour. Equipped with high-power dual motors from renowned brands, a V-belt drive transmission system, and spring flashback safety devices, this unit guarantees exceptional operational stability even under continuous heavy workloads. The double oil seal structure design on the bearing seats ensures long-term resistance to dust and debris, making it the most reliable solution for mining and power plant industries prioritizing speed and superior final output quality.
