9.10.1.1 Sugarcane Processing

At the mill, the cane is mechanically unloaded, placed in a large pile, and, prior to milling, the cane is cleaned. The milling process occurs in two steps: breaking the hard structure of the cane and grinding the cane. Breaking the cane uses revolving knives, shredders, crushers, or a combination of these processes. For the grinding, or milling,

[PDF] Effects of mixtures of grinding media of different

Abstract The effect of grinding media on milling kinetics has been generally studied using one media shape. However, very little work has been done on investigating mixtures of media shapes. Combining different grinding mechanisms in term of contacts, the volume of grinding zones can be efficiently increased when there is an optimal mixture of two or more grinding media with different shapes
