CPC Double Roll Crusher

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
