Information about the particle impact on mixer geometry is very important in understanding the secondary nucleation in crystallization, but has rarely been investigated. In this work, a method of measuring the rate of particle-impeller impaction was developed. Using this method, the effects of impeller speed, particle properties and solid concentration on the rate and position of impaction were studied.
It was found that the rate of impaction depends strongly on each experimental condition studied in this work. The preponderant position where particle-impeller impaction occurred was usually at the outer bottom corner of the blade.
