Серия 2PG дважды дробилка

The rotation of the machine is realized by motor driving the drive roller with the help of fluid coupling and reducer, and the drive roller driving the driven roller by gearbox. The two rollers run face to face with different rotation. The feeing material drop through the rollers, after squeezed, then the finished material discharged naturally, when there are some over-hard or non-breaking material appear, the roller gap can be enlarged with the contractive action of spring automatically, so the over-big or non-breaking material pass to the discharging exit and the machine is well protected. There is relative gap between the rollers running face to face, we can control the max. discharge grain size by change the gap. We can break the material of 40mm to under 10mm. In order to prolong the service life, the roller should be high quality wearable alloy cast steel structure and its surface performs quenching and high temperature tempering treated. For bearing seal, adopts 2-layer seal ring structure, which need not fill lubrication oil for long time. The main parts are: drive unit, fixed shaft assembly, mobile shaft assembly, hood assembly, frame assembly, linkage and safety device and gearbox etc. parts, which are widely used in cement, metallurgy, chemical industry, power plant, coal etc. industries to break and process the brittle and tough material. 2PG1200×1000 double-roll crusher was the Shandong province innovation plan project carried out by our company in 2004, and it has passed the provincial new product appraisal by the end of 2004 Spcifications Inlet grain size(mm)Discharge gain sizeCapacity(t/h)Power (kg)Roller Revolution(r\min)Weight(t)Φ450×500A0-1000-252011643.20-2000-50350-75450-10055Φ600×7500-3000-506022506.950-75800-6000-1001000-125125Φ900×9000-8000-1001253037.513.270-1251500-150180Φ900×9000-8000-1102505565.512.603UnstandardΦ500×15000-3000-50200-3502×374812.2Φ1000×15002005020075drive roller 6026.553driven roller 50Φ625×3020≤300504002×1607823.8
