• Fast rotating rollers independently driven
  • Crushing under pressure with identical roll’s speed
  • Roller surface smoothed, grooved or welded
  • Unique feature of roller gap adjustment by 0,1 mm
  • Material evenly distributed along crushing gap
  • 1 fix and 1 movable rollers, heavy hydraulic pistons
  • Hydraulic loosen rolls in case of foreign bodies into gap


  • Performs a gentle crushing
  • Secondary crushing between parallel rollers
  • Producing perfect desired narrow PSD
  • Constant and high performance
  • Trouble-free, dust-free with wet & dry materials
  • Overload protection hydraulically activated, to avoid damages


  • Comminution of hard and medium-hard material (lime stone, magnesia, salt, fertilizer, coke etc.)
  • Throughput up to 500 mt/hr, depending on material characteristic and particle size
  • A typical application: fine crushing e.g. from 30 mm feed size to 5 mm product size, approx. 80% target particle size largely avoiding fine grain and dust
  • Crushing roll surface according to the material characteristics (smooth, machine cut grooves or built-up welded rips)
  • Integration in semi-mobile plants possible

Mode of operation

  • Comminution of the feed material between the two rolls (fixed and moveable) by mechanical pressure up to 200 to 400 kN, hydraulically induced
  • Product particle size regulated by precise hydraulic setting of the roll gap
  • Opening of the gap between the crushing rolls in case of overload (e.g. caused by an unbreakable foreign object) within milliseconds to let that piece pass thus avoiding a shut-down


  • CPC-shaping for high critical geometries
  • Replacing existing crusher body
  • Manufacture Ad-hoc shaft + hammers
  • Satisfying continuous operation
  • Designed for lifecycle
