CPC Smooth Roll Crusher

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

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

Very long live-time due to the extremely hard chromium alloyed roll tires
Reduced maintenance due to motor/gear unit drive (Alternative: V-belt drive). Speed control and overload protection installed
Starting under load possible
No dust discharge due to specific shaft and housing sealings at the moveable roll. Operating with inert gas possible where applicable
Stainless steel for machine 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 cylinders
Extremely fast movement of the moveable crushing roll without critical cavitation of the hydraulic oil due to the design and dimensioning of the hydraulic elements
The hydraulic control elements on a manifold, avoiding sensitive piping
Automatic central greasing of the shaft bearings
Optional: shock absorber
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
