Product Introduction

HGM ultra-fine ring roller mill is a professional grinding machine for processing fine powder, micro-powder and ultra-fine powder, commonly known as three-ring mill, three-ring micro-mill, medium-speed mill and three-ring mill. The machine overcomes the defects of traditional industrial Raymond mill in application range, yield, fineness, energy consumption, service life and so on. It is an ideal substitute for Raymond mill and ball mill, and is widely used in metallurgy, electric power, chemical industry, steel, building materials, coal and other industries in China.

Superfine powder mill is mainly suitable for medium and low hardness, Mohs hardness ≤6 non-flammable and explosive brittle materials, Such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, magnesite, illite, phyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, pigment, clay, alum, graphite, fluorite, phosphate rock, potassium ore, pumice and other hundreds of materials, The fineness of the discharge product can be adjusted in the range of 325 mesh to 2500 mesh.

Working principle

HGM ultra-fine ring roller mill is composed of main mill, powder separator, powder collector, dust collector, fan, muffler, soundproof room, crusher, elevator, silo, feeder and other parts.

After the large material is broken into small particles by the crusher, it is sent to the silo by the elevator, and then through the feeder and the inclined guide pipe, the material is evenly sent to the bulk tray on the upper part of the turntable. When the mill is working, the mill roller rotates and rolls in the ring track. Under the centrifugal action, the material is dispersed to the periphery and falls into the grinding chamber, and is pressed, rolled and ground by the grinding roller in the ring.

With the high pressure fan constantly pumping the air inside the machine, the material after multi-layer grinding is brought into the powder separator, the high-speed rotating impeller screens it, the unqualified material falls back to re-grinding, and the qualified material enters the cyclone powder collector with the air flow. The density of the dust particles fall, discharged by the bottom of the discharge valve is the finished product, the less dense fine dust with the air flow into the dust collector, and adhere to the surface of the filter bag, pulse valve control high pressure air from the filter bag instantaneously spray, adhere to the dust on the filter bag fell due to the shake of the conveyor at the bottom of the two collected materials sent out for finished packaging.

Product features

01Low investment cost. In the case of the same fineness, less input than air grinding, low cost, short recovery cycle.
02With the same Fineness of finish and power consumption, the yield is more than 45% higher than that of air grinding and agitation grinding.
03The wearing parts have low loss, and all the wearing parts are made of high wear-resistant materials, which has a longer service life than the wearing parts of ordinary mill equipment.
04The operation in the grinding chamber is safe and reliable, and the sealing performance is better than that of ordinary grinding machines.
05High Fineness of finish, product fineness can reach 325-2500 mesh range.
06The use of pulse dust collector, the whole equipment in the process of operation without dust pollution, the configuration of silencer and silencer room, reduce the noise, in accordance with the national environmental standards to produce, the surrounding environment has played a role in environmental protection.
