CPC Sizer
Application
- Coarse size reduction of medium-hard and soft material (salt, coal, phosphate, clay etc.)
- Throughput up to 4.000 mt/hr, depending on material characteristic and particle size
- Feed material size up to 1.500mm, product particle size to 300 mm possible
- Design of crushing teeth according to the material requirements (number, size, position, form, hardness)
- Integration of Sizers in semi-mobile plants possible
Mode of operation
- Crushing of the feed material by the two counter-rotating rolls, either between inwards rotating rolls (Center Sizer) or between the outwards rotating rolls and the lined housing walls (Side Sizer). Successive comminution of larger lumps
- Fine feed material passes the rolls unhindered
- Typically the Center Sizers are employed for pre-crushing, Side Sizers for medium-crushing
- 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 the weld-on hard facing of the crushing teeth
- Crushing teeth in a spiral on the shaft equalizing torque peeks
- Segment plates with the crushing teeth: no dismantling of the complete roll
- Bolting or clamping of the segment plates on the shaft. Typically massive shafts
- Inclined side walls of the Side Sizers reduce the blocking tendency
- Reduced maintenance due to motor/gear unit drive. Speed control and overload protection installed
- Stainless steel housing elements in contact with product where required
- 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
