HGM series of Three-Ring & Medium-Speed MicroPowder Grinding Mill is a new kind of micro-powder processing equipment, which is invented through more than twenty times experiments and improvements, and based on twenty years of mill manufacture experience while absorbing advanced international machine manufacture techniques.

Main Application:
HGM series Micropowder Mill is a machine for producing fineness and ultra-powder. It mainly is suitable for, the low degree of hardness, the mohs' scale is not bigger than 7 level non-flammable explosive brittle material, like calcite, chalk, limestone, dolomite, kleit, bentonite, talc, mica, magnesite, illite, leaf agalmatolite, vermiculite, sepiolite, concave-convex good stone, rectorite, diatomaceous earth, barite, gypsum, alunite, graphite, fluorspar, rock phosphate, potassium ore, pumice and so on 100 many kinds of materials.

Main structure & Working principle:
Whole structure of HGM Micro Powder Mill: hammer crusher, bucket conveyer, hopper, vibration feeder, main unit, frequency conversion classifier, isolation booth、 cyclone collector device, impulse dust cleaner. It can be equipped automatically according to different requirement, such as the jaw crushing system (JAW crusher).
When work, the bulk material becomes the finely ground particles after the hammer type breaker to send in the Chu bunker stave by the elevator, again passes through the vibration feeding engine and the inclined inlet pipe, delivers evenly the material the turntable middle, the main engine electric motor through the reduction gear impetus main axle and turntable revolving, the turntable edge roller sells leads several dozens link rollers in to rub in the link roller conveyer to roll and to revolve.
The material disperses under the centrifugal force function to the circumference nearby, and falls rubs the link in the roller conveyer to surround the roller ramming, rolls the milling, the attrition crushes, the material falls after the first smashing second and third, through the high-pressured gentrifugalism air blower pavement pumping the surrounding air inspiration within the aircraft, after and will pass through the third smashing the material to lead elects the powder within the aircraft.
Chooses the powder machine internal rotation the worm gear to cause the thick material to recede the grind, the fine dust enters the tornado collection dusting equipment and along with the air current discharges by its lower part discharge valve is the end product, but has the few thin dust air current then purifies after the pulse dust remover discharges through the air blower and the silencer.

Performance and features:
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≤5μm.
5. Pro-environment
The application of pulse dust collector and muffler reduce the pollution and noise of the dust, which has reached national environment protection standard.
