Abstract
A horizontal mill for ultra-fine pulverization which has enhanced pulverization characteristics and reduced power consumption while suppressing damage or wear of pulverizing media. The pulverizing media (balls) are provided in a pulverizing chamber defined by a space between an inner cylinder and an outer cylinder which are rotated relative to each other. Large diameter pulverizing media are used and the rotational speed is kept at a low level, which is opposite to the conventional theory of using small diameter media and high rotational speeds. Since the rotational speed is low, the corresponding wear of the pulverizing media is reduced. The degradation in pulverizing performance due to the low rotational speed may be recovered by using large diameter pulverizing media. Also, the dimensional ratio between the inner and outer cylinders, the interval between the inner and outer sleeves, and the axial interval between agitating vanes are suitably selected to enhance the mill performance.
