Chemical Grinding Mill (HGM Series)

Micro Powder Grinding Mill is able to produce micropowder between 47 and 5 microns(325~3000 mesh) Grinding Mill is mainly applied to non-inflammable, non-explosive and brittle materials with Mohs hardness under six. Such as dolomite, calcite, chalk, limestone, dolomite, kaolin, gypsum, talc etc, totally more than 100 kinds of materials. Product fineness can be controlled between 325~3000 mesh (47~5 micron) Why we choose it? Advantages 1. High efficiency Under the same final size and power, the product capacity of micro powder grinding mill is twice than jet mill and agitation mill. 2. Wearing parts with a longer work life The roller and ring are made of special material, which improve the grinding efficiency a lot. For same material and final size, the lifetime of its wearing parts can reach to more than one year, about 2-5 times as long as that of vertical shaft impact crusher and turbo-mill. Especially when handling calcium carbonate and calcite, the lifetime can reach 3-5 years. 3. Security and reliability There are no rolling bearings and bolts in grinding cavity, so problems caused by bolts shedding or wear of bearings and seal components will never happen. 4. High fineness of products The product fineness can reach D97≤ 5μ M. 5. Environment friendly The application of DMC-120 pulse dust collector and muffler reduce the pollution and noise of the dust, which has reached national environment protection standard. Production Line Configuration The whole set Ultrafine Mill consists of hammer crusher, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, cyclone collector, pulse deduster system, high pressure positive blower, air compressors and electrical control systems. How does it work? Hammer crusher Crush the big materials into smaller ones Bucket elevator Send smaller ones to the hopper Vibrating feeder Send materials to the upper distribution of the turn plate (one part of main unit) Main unit When it works, numbers of rollers are moving in the ring, and the centrifugal force will force them to the edge of the turn plate and fall down. Air compressor Inhale air from outside and bring the powder in the main unit to the classifier Classifier The rotating impeller inside it will make the unqualified powder go back and grind again. Meanwhile, the right ones will enter powder collector along the air. Finally, the powder will come out from the discharge valve of powder collector
