grinding and crushing (Dean, 1995). Decreases in water content are sometimes observed while grinding solids containing essential water in the form of hydrates, likely as a result of localized heating. (See Section 12.3.1.2 for a discussion of the types of moisture present in solid samples.)

The grinding performance was reduced by the addition of Ca 2+ ions when there was a high clay percentage (40%) and a high solid percentage (70%). This paper demonstrated the importance of controlling Ca 2+ concentrations in plant water to maximize the grinding performance of kaolin-containing ores. Previous article.
