Ultrafine Grinding Mill with Longer Working Life and Higher Output

The ultrafine grinding mill is applicable to non-metallic industries, such limestone, calcite, talc, calcium carbonate, marble, kaolin, dolomite etc. grinding to produce 400-3000mesh powder. And the Mohs hardness should be less than 7 and humidity less than 6%. And this ultrafine grinding mill has the following features: higher output, wider range of applications, lower power consumption, user-friendly operation, and stable performance. Ultrafine grinding mill is capable of providing high quality filers and additives used in the papermaking, segments, plastic, rubber, pigment, printing ink, PVC and so on.

Working Principle of Ultrafine Grinding Mill:

The ultrafine grinding mill motor-driven reducer puts the grinding table in rotation. Materials to be grinded are delivered to the center of rotating grinding table by the air-block feeding device. With centrifugal force, the materials move to the periphery of the grinding table and also can be ground between roller and rings. With the pressure of the roller, the materials are ground by extrusion, grinding and shearing.

At the same time, the airflow or hot air generated by the blower jets out at a high speed evenly from the air ring around the grinding table, by which coarser ground materials are blown back to the grinding table for re-grinding, suspended materials are dried and finer materials are driven to the separator for classification. Qualified fine powder is discharged from the grinder with the air flow and collected by the collector; Unqualified coarse powder cannot go through the classifier and fall down onto the grinding table, which will be re-ground with newly-fed materials. This kind of grinding repeats until qualified fine powder is discharged. This makes the entire grinding process.

Ultrafine Grinding Mill Secondary Classifying System

The secondary classifying system includes ultrafine classifier, fan, dust collector, hopper, screw conveyor and pipes. Ultrafine classifier is the core equipment of the whole ultrafine grinding mill system. HLMX series ultrafine vertical mill is equipped with the secondary classifier system, which is capable of efficiently separating coarse powder from fine powder to obtain products of various fineness from 800 mesh to 2000 mesh.
