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
