Wet milling techniques embody the mashing in process within them, but dry milling is normally used to create a buffer stock of dry grist in a grist case, which is then mashed within 10–15 minutes directly into the mash conversion vessel. The key attribute of an effective device is to achieve complete wetting of the dry grist by mashing liquor at a precisely controlled temperature to optimise

The wet ball-milling tests were conducted at different rotating speeds (20, 25, 35, and 45 rpm) using the 20-mm balls. Figure 7a shows the wet ball-milling separation results in n-butyl acetate. Complete separations are achieved within 90, 70, 60, and 50 min of wet ball milling at rotating speeds of 20, 25, 35, and 45 rpm, respectively.

The ball mill can grind ores and other materials, wet or dry. There are two kinds of ball mills according to their ways of discharging material: grate type, and overfall type. Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties and advantages. Key properties of grinding media are size, density, hardness, and composition.

Wet milling may be a more intensive process, but it can reduce a product into more components, and into finer particles in the micron & submicron (or nanometer) particle size range, allowing for the production of a greater variety of byproducts and improved physical properties. For example, when organic pigments are reduced to sub-micron sizes, their color is stronger. This allows the customer
