HGM148 ultrafine powder grinding mill specification: Ring diameter: 1032 mm Layer: 4 piece Roller Qty: 36 piece Input size: 20 mm Final product size: 3-35 um Main unit power: 132 kw Screw feeder power: 4 kw Blower power: 75 kw Blower volum: 12292-14643 m3/h Blower pressure: 12321 Pa Main unit speed: 200 r/min Classifier speed: 500-2900 r/min Capacity; 800-5000 kg/h Main unit weight: 14.2 ton Pulse dust filter area: 256 m2 Range of application: HGM Ultrafine Powder Grinding Mill is a new type grinding equipment with optimum structural design developed for the ultrafine powder industry by our company. it is applied to the processing of nonmetallic minerals with the water content less than 10% and the Moh's hardness under6, such as calcium carbonate, talcum, barite, wollastonite, feldspar etc. It is mainly composed by feeding machine, main engine, grader, pulse dust collector, high pressure positive blower, electronic controlled device and other parts. Technical features: 1. Reliable operation of the grinding chamber: compared with common grinder, this HGM Series Grinder does not have antifriction bearing and bolt inside of the grinding chamber, so problem caused by the bearing and other sealing element will not occur and the problem of machine failure caused by the loose bolt can be avoided. 2. Long time used of the quick-wear part: all the quick-wear parts adopt high-quality wear-resistant materials. 3. Convenient maintenance: HGM series ultrafine main engine has shifting unit and does not need hoist the grader, therefore, the maintenance is convenient and efficient. 4. Double support rigid structure: the grinding roller and grinding ring will not move. 5. All-around feeding and high efficiency. 6. Compared with the same type machine, it has the features of small vibration, convenient maintenance, highly reliable quick-wear part, low operation cost.
