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
