Originální abstrakt

Chemical and process industries utilize stirred media mills for efficient fine grinding of solids. Wet grinding with vertical stirred ball mills is typically carried out for slurries containing particles smaller than 200 um, such as industrial minerals and pigments. Filtration is an important unit operation, which is performed in order to reduce the water content of the slurry after grinding and concentration, and prior to drying and transportation. Pressure filters are used to obtain the maximum dryness of the product. A number of properties of solids affect the filtration performance. The particle size and shape, the width of particle size distribution, and the net surface charge of the particles are among the factors having a significant influence on the filtration characteristics.
