Abstract

The present invention provides a micro-media agitator mill for particle size reduction and dispersion of particulate size matter in slurry comprising a cylinder having inlet and outlet for slurry, wherein inner surface of cylinder has bellows-like deflectors; atleast one rotating shaft adapted centrally to the cylinder; a series of rotating discs adapted on the shaft, wherein each disc have an outer opening for passing of the slurry; and a deflector provided on the rotating shaft between the two rotating discs matching with the deflectors provided on the shaft wherein deflectors in combination with the two rotating discs form a compartment between the two disc and directs the slurry and grinding media to circulate within the compartment improving attrition between the grinding media and increasing the retention time of the slurry in the mill. Further, the cylinder has plurality of deflectors like bellows on the inner surface matching with deflectors provided on the outer surface of outer spacers thereby forming at least one compartment in combination with the rotating discs between the two rotating discs directing the slurry and grinding media to circulate within the compartment thereby improving attrition between the grinding media and increasing in the retention time of the slurry in the mill.
