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
