Hot Sales Construction Machine Ultrafine Grinding Mill

Description Of Our Grinding Mill
The whole set HGM Ultra Fine Grinding mill machine, mainly applied in metallurgy, chemical combination, paper making, Rubber making construction, mining, cement and other fields, usually 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. The stones for grinding are graphite, calcite (calcite carbonate, calcium carbonate), chalk, limestone, dolomite, kaolin, gypsum, etc, totally more than 100 kinds of materials. Product fineness can be controlled between 0.047 and 0.005mm.

Advantages And Feature Of The HGM Series Grinding Mill:
1. High efficiency.Under the same final size and power, the product capacity of ultrafine mill is twice than jet mill and agitation mill.
2. Longer lifetime of spare parts.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 2-5 years.
3. High safety 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 pulse dust collector and muffler reduce the pollution and noise of the dust, which has reached national environment protection standard.


Ultra-fine Powder Grinding Mill Working Principle:
Host motor through a speed reducer drives the spindle and the turntable, turntable driven by the column pin dozens of ring roll in the ring rolling and rotating raceway. Bulk material by hammer crusher broken into small particles by the hoist into a storage bin, electromagnetic vibrating feeder will even materials to middle upper turntable, material under the centrifugal force scattered to the circumference, and fall into the mill race was ring roller stamping, rolling, polishing and grinding ring, the first layer of crushed material in the second layer and the three layer, suction high-pressure centrifugal fan external air suction machine, and after the meal third layers of crushed into powder selecting machine. The turbine rotating powder machine in the coarse particles fall heavy grinding, fine powder with airflow into the cyclone powder collector and the lower part of the discharge valve discharge is finished, the air flow with a small amount of fine dust through the pulse dust collector after purification by the blower and exhaust muffler Our Service
