SCM Ultrafine Mill

For almost 30 years,SBM is engaged in grinding mill design and maintenance.The SCM ultrafine mill is specially designed for super fine powder grinding.Absorbing the latest technology of micro-powder mill at home and abroad.The output size of the SBM SCM ultrafine mill can reach 2500mesh (5um).Now it’s growing more and more popular in super fine powder grinding.
SCM ultrafine mill features multi-function and can be used as crushing articles and can also be independently used as graded machine application.Besides,SCM ultrafine mill can also be used seriesly to the graded machine and can achieve 1-3 particle size particles ,which can form the closed or open work with other crushing equipemnt ,thus realizing the one machine and multi-function.

Application of SCM Ultrafine Mill

SCM ultrafine mill is mainly used to produce fine powder and super fine powder.SCM ultrafine mill is mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, fertilizer and mining etc.

SCM ultrafine mill can produce powder from non-flammable and non-explosive mineral materials with Mohs hardness below 9 and humidity below 8%, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talcum, talc, magnesite, illite, pyrophyllite, vermiculite, sepiolite, etc.

Distinctive feature of SCM Ultrafine Mill

  1. High capacity,low consumption and low cost,advanced cavity design.
  2. The main frame and the base are completely soft-linked.It can avoid the vibration damage and improving the precision of the classifier.
  3. Under the same condition,the capacity of SCM ultrafine mill is raised by 40% compared with airflow mill and mix mill.
  4. Supper fineness of finished product,can according to the need can be adjusted between 325 mesh to 2500 mesh.
  5. Grinding chamber without rolling bearings, screws, safe and reliable, stability is good.
  6. Equipped with pulse dust catcher and muffler, greatly reduced the dust pollution.

Working principle of SCM Ultrafine Mill

The motor of SCM Ultrafine Powder Mill drives the main shaft and every turnplate round through the reducer.Small material crushed is transported into hopper by elevator, and then vibrating feeder shall feed material to the central part of upper turnplate evenly. The material falls to circle under the centrifugal force and comes down to raceway of ring to be crushed into powder.Turbine in the separator makes the coarse powder drop down and regrinded and the fine powder shall go into cyclone powder collector together with air current and go down through discharge valve as final product,at the same time,air current with a little dust goes out through blower and muffler after purified by filter.
