CPC Smooth Roll Crusher
Application
- 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
Mode of Operation
- 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
Features
- 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
