Product Description
Three-ring Micro Powder Mill(ultrafine mill) is for super-fine grinding materials with hardness less than 6 in Moh’s hardness scale and humidity less than 6 percent,such as kaolin, limestone, calcite, marble,talcum, barite ,garnet, gypsum, dolomite, bentonite mud,mica, pyrophyllite, sepiolite, diatomite, graphite, alunite, fluorite, potassium feldspar, phosphorite, pigment and so on. The granularity of the end products is 400-2800 meshes (0.044-0.0055mm).
It can be used for feeding materials with less than 3% in moisture and less than 10mm in feeding size. It enjoys extensive application in further processing of nonmetallic minerals with Mohs hardness rating of less than 5. It is also applied for ultra-fine grinding in variable industries such as chemical engineering, dyestuff, synthetic resin, coating materials, agricultural chemicals, starch, food as well as advanced technology in national defense. Excellent fineness, high output and low cost of processed products lead to enormous economic returns.

Mining, building materials, chemicals, metallurgy and other industries.
Product Advantages
1. Advanced grinding cavity design.High capacity and low consumption.
2. Easy installation of the whole equipment, little land coverage without large civil engineering projects. It can be put into production promptly after installation. The stable and reliable working performance allows continual production, high fineness of processed products, thus ensuring product quality.
3. High quality grinding media.Large range of fineness adjusting.
4. It has a fully integrated system. Its built-in classifying system is able to complete two procedures of ultrafine grinding and ultrafine classifying. It is also equipped with efficient cyclone separator or dust collecting system. The whole system works under negative pressure without dust spreading outwards, an ideal equipment for your clean production.
5. The whole grinding mill system with a compact structure could save factory space, with a lower foundation construction cost, it’s a cost-effective investment.
Working Principle
General:
Crushing — Grinding — air classifier — Collecting– dust filter
Detailed:
After being crushed by hammer crusher, the big materials become small ones and they are sent to the storage bin by elevator. The electromagnetic vibrating feeder sends them to the middle of first dial evenly; the materials will be driven to the edge of dial by centrifugal force, and fall into the ring channels and are pressed, crushed and ground by the grinding rings and rolls. Then the materials fall into the second and third ring and crushed and ground.
The high pressure centrifugal blower inhales air from the outside and blow the materials which are ground in the third ring to powder Separator. The rotating turbo in the powder Separator makes the coarse materials return to the mill and reground, while the fineness mixes with the air and be drawn to the cyclone and be discharged from the discharging valve which is in the bottom of it. The air which mixed with very little fineness are purified by impulse dust catcher and discharged by blower and muffler.The product fineness(D97=3-35um) can be adjusted at any time according to customer demand.
