These types of plants are suitable to obtain products at very high fineness and with high specific surface. As they are provided with an air circuit, hot gas can be used in those cases, which require to reduce a small moisture content percentage.
The SUPER-CENTAURO plant grinds and classifies within a closed or open circuit, which basically includes: ball mill, high efficiency classifier, cyclone, fan and bag filter.
Mill shell can be internally lined with abrasion resistant steel linings, or with silex or alumina blocks in those cases which iron contamination has to be prevented.
The air vane leading the product from the Mill gets to the Classifier where the fines and oversize classification as it is required takes place. The change of fineness is done at distance from the control panel, immediately and without the need of stopping the plant running. Oversizes are led again to the Mill, whilst fines keep on being suspended in the air vane until they are collected by the Cyclone or by the Bag Filter.
The grinding room ambient is perfectly clean, as any release of dust because of the pressure, always under the atmospheric, in the mill and in the conveying and classification circuit is prevented. The partial air renewal is carried out through a bag filter.
