What is a Ultrafine Mill?

There are various types of ultrafine mill in market, such as SBM's SCM series ultrafine mill. SBM's SCM ultrafine mill is widely used for micron powder producing. The output size can reach 2500mesh (5um). It is suitable for grinding the material with middle and low hardness, moisture below 6%, and the material should be non-explosive and non-flammable, such as calcite, chalk, limestone, dolomite, kaolin, etc. The size of the finished product can be adjusted between 325-2500 mesh as well.

SBM designs and manufactures a comprehensive line of grinding equipment for mineral processing. SCM series ultrafine mill is specially designed for micron powder producing. Due to its unique features of ultrafine end products and high grinding efficiency, now it's growing more and more popular with its reliable technology and perfect after-sale services.

Working Principle of Ultrafine Mill

The main motor drives main axle and every layer rotating by the power of reducer. Dial drives numbers of rollers rolling and rotating in the ring by pintles. Big materials are crushed into small particles by hammer crusher. Then they are sent to store house by elevator. Vibrating feeder send the materials evenly to the middle of the upper dial. Under the function of the eccentricity, the materials fall into the ring to be pressed, crushed and milled into pieces by rollers. After the first crush, materials fall into the second and third layer. The pumping of the high-pressure centrifugal blower put the outside air into the machine. The coarse powder mill will be brought into the classifier.

Frequent Questions From The Customers

Q: The Moisture Of My Gypsum Is About 10%, Is The Machine Suitable?

A: generally, our SCM series mill is suitable for medium and low hardness material with moisture below 6%. But we can add a dryer before grinding and dry the gypsum until the moisture suitable for entering the mill. Because if the material with too much moisture, the heat produced while grinding will change the airflow volume while will lead to the low flour yield. So in the grinding process, the customer should avoid grinding material with too much moisture.

Q: How About The Fineness Of This Machine?

A: the output size of SBM SCM series mill can reach 2500mesh (5 um). The output size can be adjusted between 325 to 2500mesh. The one-time final product fineness can reach to D97 ¡Ü 5¦Ìm.
