In addition, the ball‐milling effect on crosslinking performance of stone starch was also investigated. It was observed that the milled starch granules lost surface smoothness at high milling loads (25 and 30 g), while some granules were squashed at low milling loads (15 and 20 g).
Optimization of mill performance by using
The performance of ball mills is very sensitive to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size. A pilot plant investigation with an overflow mill discharge has been conducted. For a given throughput, it seems that the pool size has a major influence on the product grind.
