ZM Series impact mills with internal classifier structure and principle(roller mill,can crusher)The mills are insisted in two parts of impact grinder and turbo classifier. The materials are fed into the mill by variable speed spiral and pulverized by the actions of the acute impacting, smashing, friction and shear as result of particles with both impact hammers at high speed rotating disk and saw-tooth-out-ring and classified by rotating classifying wheel, the required fineness and product through blades of wheel is entered to collecting product system, while the coarse particles is returned to the mill. To adjust rotating speed of classifying wheel, can obtain qualified product.echnical function :Paramenters/ModelZM100ZM120Rotor diamatermm9351150Round Speedr/min22501000motor power (kw)CrushClassifyCrushClassify55-751575-10022Material guanularitymm<15<20Product granularityμm8-1008-100Productionkg/h100-5000200-8000Main motor weightkg45007500
