Similarly, Shoji and coworkers (1973) demonstrated that the rotary 120 ball mill mixed efficiently, without segregation, when the charge mass was just sufficient to fill the voids between the balls. Kaneniwa and Ikekawa (1977) showed that an interac tion of polyvinylpyrrolidine with various excipients occurred on a molecular 'level when mixed in a rotary ball mill.

Ball mill. The material to be ground is added to just fill, or slightly more than fill, the voids between the balls. Water may or may not be added. The shell is rotated at a speed that causes the balls to cascade, thus reducing the particle sizes by repeated impacts. The operation may be batchwise or continuous.
