Unique Advantages

To achieve ultrafine, high purification, functional, intelligent, carbon reduction, energy conservation and environmental protection is the mission and responsibility that time has given us.

High grinding efficiency,High energy efficiency.

Calcium carbonate feed size <10 mm, could grind material size less than 10 μm (with pass rate of 97%), and fine powder size <2.5μm accounted for about 40%, specific surface area is big.It has the advantages of high-efficiency, low-loss of high-speed impact mills, and product fineness is close to jet mill.

Favorable product granularity and stability

Ideal equipment for current dry grinding method to produce non-metallic mineral fine powder.The main machine is built-in classifier. Unique structure of classifying impeller, favorable classifying effect and no particle pollution. Particle sizes can be adjusted as needed.Could produce powder of D97=3-8μm, and also produce ordinary powder of D97=10-40μm.

More environmentally friendly and energy saving

Negative pressure, with higher efficiency dust collector, less dust; semi-automatic control and unique process to greatly improve production efficiency, it is the lowest energy consumption grinding equipment at present.

Low wear

The grinding wheel and grinding ring are made of special wear-resistant alloy steel, service life is increased by 2~3 times.

Working Principle

Creating the future of advanced materials with powder technology.

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.
