Limestone Vertical Ultrafine Grinding Automatic Grinder Ring Roller Mill

Application: Widely used in calcium carbonate (calcite, marble, limestone, chalk), barite, kaolin, dolomite, magnesite, alumina, superfine cement, slag, steel slag and other industries.

Features and Advantages:

1.Available D50:1.5~45μm

2.Large output: grinding calcium carbonate, the fineness is 10μm, the output can reach 3 tons / hour or more

3.Unique structure of classifying impeller, favorable classifying effect and no particle pollution.

4.Favorable product granularity and stability,Ideal equipment for current dry grinding method to produce non-metallic mineral fine powder such as calcium carbonate.

5.Fine powder can be completely recycled without polluting the environment.

6.Lower installation power, wide application, high cost-performance.

Working Principle:

Roller mills(micro powder roller mill,fine roller mill,ring roller mill,roller grinding machine,automatic roller mill,three/four roller/rolling mill) are mills that use cylindrical rollers, either in opposing pairs or against flat plates, to crush or grind various materials, such as grain, ore, gravel, plastic, and others.

Roller grain mills are an alternative to traditional millstone arrangements in gristmills.

Roller mills for rock complement other types of mills, such as ball mills and hammermills, in such industries as the mining and processing of ore and construction aggregate; cement milling; and recycling.

Transmission device connects with main shaft. The top of shaft connects with rotor structure. The rotor structure has peripheral shaft. Peripheral shaft is installed with roller.

When the main shaft starts to rotate, peripheral shaft rotates too, which would make the rollers revolve around main shaft and also rotate round peripheral shaft.

The roller would create strong centrifugal force during the rotation and revolving, and grind material with stator. The ground material would fall down to the distribution plate.

The distribution plate and the main shaft would rotate at the same time, and bring material to the round ring.

Under negative pressure, it would go along the distribution ring to the classifier chamber. Qualified fine powder would go through the classifier wheel and into the collector, while coarse powder would fall down back to the milling chamber for further grinding.
