CPC Concasseurs à double rouleaux

Application

  • Coarse size reduction of hard and medium-hard material (lime stone, magnesia, salt, fertilizer, coal etc.)
  • Throughput up to 2.500 mt/hr, depending on material characteristic and particle size
  • Feed material size up to 1.200 mm, product particle size from 10mm to 300mm possible, according customers demand
  • Design of crushing teeth according to the material requirements (number, size, position, form, hardness)
  • Integration in semi-mobile plants possible

Mode of operation

  • Crushing of the feed material by teeth as well by pressure, hydraulically induced. Successive comminution of larger lumps
  • Product particle size regulated by precise setting of the roll gap
  • Opening 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
  • 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 live time due to the 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 very stiff quill 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
  • Stainless steel housing parts in contact with feed material where necessary
  • 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
  • Extremely fast movement of the moveable crushing roll without critical cavitation of the hydraulic oil due to design and dimensioning of the hydraulic elements
  • The hydraulic control elements on a manifold, avoiding sensitive piping
  • 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
