Roll Crushers – Single & Double Stage

Roll Crushers with Single & Double Rolls

Roll crushers deliver consistent three-dimensional product sizing control. Continuous intermeshing teeth reduce the amount of fines present in finished product, while crushing and eliminating over-size materials. Straightforward housing mechanisms and an enclosed gearbox allow for easy access and maintenance.

Shafts, bearings, and other components are all heat-treated, forged from durable alloy materials, and designed to handle extreme impacts and abrasive materials. The result is a durable, rugged machine that requires little maintenance compared to other crushing solutions. The primary (and only, in the case of single stage units) drive can be structured as a sheave or flywheel V-belt. Secondary drives, in the case of double stage roll crushers, can run on cog-belts or super durable roller chains.

Roll crushers (whether single stage or double stage) are designed to size and process a wide variety of materials, including:

  • Coal
  • Coke
  • Soft Ores
  • Industrial Minerals
  • Friable Materials
  • Fertilizer
  • Potash
  • Limestone
  • Glass
  • Salts
  • Lime
