MW Series Micro Powder Mill

product introduce:MW annular roller micro powder mill (medium-speed micro powder mill) is a new type of equipment designed for ultra-fine powder processing users according to the development trend and demand of the domestic mill market. It is mainly applicable to non-flammable and explosive materials with mohs hardness below grade 7 and humidity below 6%, such as calcite, calcium carbonate, dolomite, talc, etc.

Applications: calcium carbonate grinding, gypsum grinding, power plant desulfurization, non - metallic mineral powder, coal powder preparation, etc.

The WM series three-ring medium-speed micro-powder mill has accumulated many years of production experience of daybreak regrinding. Based on the advanced mechanical manufacturing technology of Sweden and a new type of ultra-fine powder processing equipment tested, improved and developed more than 20 times later, the crystallization of advanced technology is the latest product in the world trend of rolling mill.It is mainly suitable for the processing of non-combustible, explosive and brittle materials with mohs hardness below grade 6, such as calcite, limestone, dolomite, kaolinite, bentonite, mica, illite, pyrophyllite, barite, sepiolite, fluorite, potassium ore and more than 200 kinds of materials.


1、Under the same fineness and power consumption of finished products, the cost is lower than the investment cost of airflow grinder, with short cycle time but high output.

2、Low consumption of consumables.

3、The main motor drives the spindle and each layer of rotating disk through the reducer. The rotating disk drives dozens of annular rollers to roll and rotate in the grinding ring raceway through the plunger pin.

4、nvestment is inefficient.

Working Principle

The main motor of the MW medium-speed micro-powder mill drives the spindle and every layer of rotating table to rotate through the reducer, and the rotary table drives dozens of ring rollers to roll and rotate in the grinding ring raceway through the column pin.Big break material into small particles into the storage bin by elevator, materials uniform electromagnetic vibrating feeder will be the center of the wheel, the material under the action of centrifugal force, the circumference and is divided into internal circular runway is stamping part of roll, roll grinding, grinding and crushing, after crushing material particle size and structure of the first layer integration, and fall into the second layer, grinding and grinding powder into the third layer, in order to achieve the ideal particle size requirements.The suction action of the high pressure centrifugal fan draws the external air into the machine, making the powder enter the machine through the third layer comminution.The flow of rotary worm wheel in separator makes the coarse particle material fall back and grind again.The fine powder enters the cyclone separator along with the air flow and is discharged from the lower discharge valve.The air flow with a small amount of fine dust is cleaned by fans and mufflers.
