RLM Ring Roller Mill

Relying on the grinding roller orbital revolution and rotation on the grinding ring track to finish grinding.

Built-in classifying wheel, available D50:2～45μm.

Compared with Raymond mill or ball mill, finer powder, lower operating cost.

Suitable for ultra-fine processing of nonmetallic minerals such as calcium carbonate.

High grinding efficiency

It has the advantages of high-efficiency, low-loss of high-speed impact mills, and product fineness is close to jet mill

Favorable classifying effect

Unique structure of classifying impeller. Particle sizes can be adjusted as needed.

Energy saving

Negative pressure, with higher efficiency dust collector, less dust

Low wear

The grinding wheel and grinding ring are made of special wear-resistant alloy steel

Working Principle

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.

Note	The above data is based on heavy calcium (feed size <10mm, Mohs hardness <5%), affected by different materials, differences in production areas etc, above data is for reference only. The particle size was measured by Omega particle size analyzer and Malvern particle size analyzer.

Note: The production capacity is closely related to the particle size, specific gravity, hardness, moisture and other indicators of the raw materials. The above is only for selection reference.
