(Page 1) Many branches of the chemical process industries (CPI) make use of impact comminution to process solid matter such as minerals foodstuffs pharmaceutical products and above all products for the chemicals industry. Impact comminution is also used for coarse crushing but the focus of this article is fine grinding with end-product particle sizes below 500 micron.

However it was found that conventional grinding had a very high power consumption and that contamination of the mineral surface by iron from the steel grinding media adversely affected flotation performance. It was concluded in 1990 that there was no suitable existing technology for grinding to the fine sizes in the base metals industry.
