Micro-powder Grinding Mill is a professional piece of equipment designed for fine and ultra-fine powder processing. It is mainly used to grind various ores, chemical raw materials and other materials into fine or ultra-fine powder products.Specifically, the Three-Ring Medium-Speed Micro-powder Grinding Mill is especially suitable for processing medium and low hardness, non-flammable and non-explosive brittle materials with Mohs hardness below 6. Typical applicable materials include calcite, calcium carbonate, dolomite, kaolin, bentonite, mica, diatomite, barite, graphite, etc.
calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, and vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alunite, graphite, fluorite, rock phosphate, kalium ore, pumice, fly ash, etc.
The main motor of the micro-powder grinding mill drives the main shaft and turntable to rotate via a reducer. The roller pins on the edge of the turntable drive dozens of grinding rollers to roll in the raceway of the grinding ring.
After large materials are crushed into small particles by a hammer crusher, they are lifted to the storage bin by an elevator, then evenly fed to the bulk material plate on the upper part of the turntable through a vibrating feeder and an inclined feed pipe. Under the action of centrifugal force, the materials are scattered to the circumference and fall into the raceway of the grinding ring. Here, they are impacted, rolled and ground by the ring rollers, gradually forming powder.
The high-pressure fan draws external air into the machine through suction, and carries the ground powder into the powder selector. The rotating impeller inside the powder selector separates the coarse materials, which fall back to the grinding chamber for re-grinding, while the qualified fine powder is carried by the air flow into the cyclone powder collector and discharged from the bottom discharge valve as the finished product. The air flow containing a small amount of fine dust is purified by the pulse dust collector, then discharged through the fan and muffler, ensuring clean and environmentally friendly operation.

1. High Efficiency and Energy Saving
Under the same conditions of finished product fineness and motor power, its output is more than twice that of air flow mills, stirring mills and ball mills, realizing efficient and energy-saving operation.
2. Long Service Life of Wear Parts
The grinding rollers and grinding rings are forged from special materials. Under the same material and finished product fineness conditions, the service life of its wear parts is 2-5 times longer than that of impact crushers and turbine crushers. Generally, the service life can reach more than one year, and when processing calcium carbonate and calcite, the service life can be extended to 2-5 years.
3. High Safety and Reliability
There are no rolling bearings or screws in the grinding chamber, which avoids the common problems of easy damage to bearings and their seals, as well as machine damage caused by loose screws, ensuring safe and stable operation.
4. High Product Fineness
The fineness of the finished product can reach D97≤5μm in one processing, meeting the high-precision application requirements.
5. Environmental Protection and Cleanliness
A pulse dust collector is adopted to effectively capture dust, and a muffler is equipped to reduce noise, fully complying with relevant environmental protection standards.
