Fine Grinding - A Refresher - 911 Metallurgist

2017-2-1  INTRODUCTION Building a case for fine grind modelling requires reviewing some theory before building a framework for doing fine grinding calculations. The actual calculation procedure recommended is easy and can be applied by plant metallurgists. Don’t be frightened by the theory; the end result is reasonably simple.

Fine grinding of silicon wafers - Kansas State University

2006-5-21  Fine grinding of silicon wafers requires high predictability and consistency, which requires the grinding wheel to possess self-dressing ability, i.e., after initial truing, the wheel should not need any periodic dressing by external means. In other words, there should be “a perfect equilibrium

Wills' Mineral Processing Technology ScienceDirect

Media ball sizes, for example, range from about 20 mm for fine grinding to 150 mm for coarse grinding. Tumbling mills are typically employed in the mineral industry for primary grinding (i.e., stage immediately after crushing), in which particles between 5 and 250 mm are reduced in size to between 25 and 300 µm.
