CPC Hybrid Crusher

Application

  • Coarse size reduction of hard, medium-hard and soft material (lime stone, dolomite, magnesia, salt, coal, clay, oil shale etc.)
  • Throughput up to5.500 mt/hr, depending on material characteristic and particle size
  • Feed material size up to 1,500mm, product particle size down to 300mm possible, 50mm for secondary crushing stage
  • Design of crushing teeth according to the material requirements (number, size, position, form, hardness)

Mode of operation

  • Combination of the characteristic of the Double Roll Crusher with the performance of the Sizer
  • Crushing of feed material by teeth of the two counter-rotating rolls. Successive comminution of larger lumps
  • Product particle size regulated by precise 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
  • Crushing teeth in a spiral on the shaft equalizing torque peeks
  • No clogging of the rolls by sticky material due to specifically designed scrapers
  • Final product with small portion of fines due to limited speed of the rolls

Features

  • Very long lifetime due to crushing teeth with replaceable picks made of tungsten steel. Replacing the picks, only, in case of wear, thus reducing spare part costs. Alternative: weld-on hard facing of the crushing teeth
  • Single segment plates with the crushing teeth: no dismantling of the complete roll for replacing wear parts
  • Bolting or clamping of the segment plates on the shaft. Typically massive solid shafts
  • Reduced maintenance due to motor/gear unit drive (Alternative: V-belt drive). Speed control and overload protection installed
  • Integrated flywheel equalizing torque peeks thus reducing required motor power
  • No dust discharge due to specific shaft and housing sealings at the moveable roll. Operation with inert gas possible where applicable
  • Guaranteed permanent parallel position of the crushing rolls even under partial overload (e.g. by strange material) due to hydraulic “Cross Junction” of the hydraulic working cylinders
  • Extreme fast movement of the moveable crushing roll without critical cavitation of the hydraulic oil due to the design and dimensioning of the hydraulic elements
  • Automatic central greasing of the shaft bearings
  • Design of the discharge seal for easy and quick movement to a maintenance position
  • Local Operating Panel (LOP) with PLC. Communication interface to the plant control units available
