High efficiency super fine grinding mill for mining industry

Super fine grinding mill is a high-efficient ultra fine powder grinding mill, comparable to air-blast mill, newly designed by our experts on the basis of industrial mill manufacturing experience for many years, which adopts the theory of fluidics and successfully solves the problem of high cost in domestic air-blast mill.

The new type of grinding roll assembly changes the traditional structure, using various means of sealing, getting rid of three defects of old assembly, i.e. oil leak, dust coming in, and disalignment.


The main features of the Super fine grinding mill

1.Compared with other mill, the grinding pressure of grinding roll to the materials has increased 800-1200kg under the function of superfine spring.

2. Energy saving, in case of same output and fineness, its systematic energy consumption is only one-third of that in the jet mill.

3. Small investment, and high efficiency, in case of same output and fineness, the price is only one-fourth of that for the air-blast mill.

4. The grinding device adopts overlapping multi-stage sealing with good sealing performance.

5. The dust collecting effect of ultrafine powder mill fully meets the national dust emission standards.


Advantages of the new type assembly:

1. No oil leak; it is not necessary to add oil every shift but to add a little lubricating oil every three days or a week.

2. High degree of sealing; the dust is not easy to enter into the assembly in the process of production, thus prolonging the service life of the bearings.

3. In the process of production, it is possible to adjust the bearing clearance according to the wearing degree of assembly bearing, ensuring the concentricity of the upper and lower bearings. The bearings can be used continuously for more than 10 months.

4. The new type of roll assembly extends the period of maintenance, reduces the strength of repair and production costs, improves production efficiency, and bring considerable economic benefits to the users.
