sbm ultrafine mill also named scm super fine grinding mill is specially designed for super fine powder grinding. the feed size to ultrafine mill is limited to the maximum size that can be practically conveyed and introduced into the mill. this ultrafine mill can be installed directly as the only powder grinding equipment in the whole grinding plant or it can be used as further-grinding machine after ball mill grinding or coarse powder grinding.
scm ultrafine grinding mill appliion
scm series super thin grinding mill is mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, fertilizer and mining etc. the grinding mill can produce powder from non-flammable and non-explosive mineral materials with mohs hardness below 9 and humidity below 8%, such as barite, lisbmne, quartz, calcite, granite, porcelain clay, basalt, gypsum etc.
currently sbm undertakes around hundreds of grinding plant each year. with its growing perfect services, sbm will be able to provide a unique end-to-end solution including products maintenances.
scm super thin grinding mill main features and benefits
1. high efficiency. under the same condition of finished particle size and power of motor, the output of thin grinding mill is 40% higher than airflow grinding mill and whisk grinding mill.
2. environmental protection. pollution and noise are lightened by using deduster and muffler so as to reach the requirement of national environmental protection when using thin grinding mill.
3. high safety. no axletree or bolt is used in the grinding chamber, so there will be no worn out problem of bearing and sealing parts, and also no loose of bolts in the running of thin grinding mill.
4. finished size can reach to d97≤5μm.
5. high using rate of spare parts.
scm ultrafine grinding mill working principle
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 grinding machine. the coarse powder will be brought into the classifier.
scm super thin grinding mill main parts
the whole system of scm series super thin grinding mill consists of main unit, deceleration machine, blower, hammer crusher, dustpan elevator, electro-magnetic vibrating feeder, impulse dust cleaner, piping device, cyclone collector device,classifier, high-pressure motor and muffler. axletree seat and effuser air-in are built on the main seat. the antrum of mill is on the effuser air-in. multi-layer dial set on the main axle lies in the middle of grinding antrum. there are sevel rollers distributing evenly on each dial. a gear reducer and motor are set on the main seat, while the powder collector is set on the top of the antrum mill.
