Grinding Mill

SCM Ultrafine mill

Xuanshi as a large machinery manufacturing company, main production and export mining equipment(SCM Ultrafine mill), the company has the world advanced crushing, grinding and milling technology.

SCM series super thin mill(Ultrafine mill) is on the bases of our company’s production experience for more than 15 years. We absorb advantags from the same trade abroad and at home. We review, research and try on 12 kinds of mills and horizontal hammer cr

SCM Ultrafine mill Applications :

This grinding mill is a equipment which produces thin powder and super thin powder. It is applicable to non-flammable and non-explosive materials with hardness less than 6, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talcum, talc, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alum earth, graphite, fluorite, variscite, potash ore, floatstone.

SCM Ultrafine mill Features and Benefits :

1. High efficiency. Under the same condition of finished particle size and power of motor, the output is 40% higher than airflow mill and whisk mill.

2. Environmental protection. Pollution and noise are lightened by using deduster and muffler so as to reach the requirement of national environmental protection.

3. High safety. No axle tree 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.

4. Finished size can reach to d97≤5μm.

5. High using rate of spare parts.

SCM Ultrafine mill Construct :

The whole set of MTM medium speed trapezium mill consists of main mill, powder classifier, speed reducer, blower, jaw crusher, bucket elevator, vibrating feeder, storage bin, bag filter, pipe and fitting, cyclone powder collector, electric control cabinet, electric motor, etc.

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 machine. The coarse powder mill will be brought into the classifier.
