HGM Series Super Micron Mill And Micro Powder Production System Ore Grinding Mill

1. Working principle

The motor of the micro grinding machine drives the spindle and the turntable of each layer to rotate through the reducer, and the turntable drives dozens of ring rollers to roll and rotate freely in the raceway of the grinding ring through the pin.

Large pieces of material by the hammer crusher broken into small particles into the storage bin by elevator, electromagnetic vibrating feeder will material evenly to the centre of the wheel, on the material under the action of centrifugal force to circle around, and fall into the inside of the ring raceway is stamping ring rolling, roll grinding, grinding and crushing, the material after the first layer crushing and fall into the second and third layer, Small particles of material after thousands of times of impact, rolling and rubbing into ultrafine powder, in the high pressure centrifugal fan suction action will be external air inhalation machine, and the third layer of pulverized coarse powder into the powder separator.

The eddy current generated by the rotating turbine in the powder separator makes the coarse granular materials fall back and reground. The fine powder enters the cyclone powder collector with the airflow and is discharged from the discharge valve at the bottom of the cyclone powder collector, which is the finished product. The airflow with a small amount of fine dust is purified by the pulse dust collector and discharged through the fan and muffler.

2. Performance characteristics

(1) The micro grinding is efficient and low consumption. Under the same material, power and fineness of finished product, the output is 40% higher than that of air mill and agitation mill.

(2) The micro mill has a long service life. In the case of the same fineness of materials and finished products, the service life of wear parts is longer than that of impact crusher and turbine crusher, generally up to more than 1 year.

(3) There is no rolling bearing or screw in the grinding cavity. There is no bearing and its seals and fragile screws easily loose and destroy the machine and other problems

(4) The fineness of the ultrafine grinding product can reach D97 ≤5μm at one time
