Calcium Carbonate Ultrafine Grinding Mill
Ultrafine calcium carbonate refers to calcium carbonate whose primary particle size is between 0.02 and 0.1μm. Ultrafine calcium carbonate was first developed by Japan, which takes leading place in the development, production and application of ultrafine calcium carbonate. Japan has been able to produce different crystal forms, different particle size, different surface coating and no certain shape ultrafine calcium carbonate powder.
Ultrafine calcium carbonate powder is the best powder in all kinds of calcium carbonate powder. And it is also the cheapest nanomaterial. It has special quantum size effects, small size effects, and surface effects, which make it more powerful than conventional powder materials. It is more powerful in the aspect of strengthening, transparency, dispersion, thixotropy and floating.
The way to produce ultrafine calcium carbonate powder by ultrafine grinding mill:
Elevator conveys the crushed calcium carbonate (usually less than 10mm) to the feeding hopper, which will be feed into the grinding house by the belt conveyor or screw conveyor.
In the grinding house, there are three or four layers of roller and rings. The grinding rollers on the rotary table rotate with the help of central shaft. And there is a flexible gap between roller and ring. When the ultrafine grinding mill works, the rollers will move towards the ring because of centrifugal force. The material will be ground the roller and ring. So calcium carbonate can be ground into ultrafine powder with higher passing rate.
The ultrafine calcium carbonate powder with required fineness go through the classifier into the pulse-jet collector, and the coarse powder will fall down into the grinding chamber to be reground. And the temperature in the grinding house can also be controlled by our special system to improve the whiteness of the calcium carbonate powder.
Special Features of Calcium Carbonate Ultrafine Grinding Mill:
1.Perfect contact between rollers and ring: The arc or curved surface increases their effective working surface and improves the crushing efficiency. The rollers and rings contact surface and shapes should be consistent and tightly fit, which is good to the production of fine powder.
2. Improved hardness of rollers and rings: this not only guarantees longer working life, but also the powder is not easy to be contaminated.
3. Pulse-jet Collector: 99.99% of the ultrafine powder can be collected, which is also environment-friendly.
4. Inverter for motor speed control, which can lower power consumption and adjust rotation speed of the mill and classifier to produce different fineness.
