DOUBLE ROLL CRUSHER
DR13
Features
- Solution for medium-hard rock as well as sticky and soft materials (coal, limestone, clay, salt, etc.)
- Weld-on hard-faced crushing teeth with various configurations for most difficult applications
- Integrated flywheel equalizing torque peaks, thus reducing required motor power
- Permanent parallel position of crushing rolls due to hydraulic “Cross Junction”, even in case of partial overload
- Efficient crushing of materials with less content of fines and low dust emissions
- Monitoring by local operator panel
Advantages
- Highest lifetime of crushing segments
- Fully automatic operation
- Generation of various degrees of product fineness
- High experience in custom-tailored product particle size distribution
- Fast and efficient maintenance of crushing segments
- Fully sensor-controlled to avoid downtimes
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
