Wet milling is more complex than dry milling, thanks to the addition of a liquid, but this process also has the power to reduce a product into finer particles. This allows for the production of a greater variety of byproducts and also can result in improved physical properties in your final product.

ادامه مطلبprocess grinds the powder materials by impact/collision & attrition. • Milling can be dry milling or wet milling. In dry milling, about 25 vol% of powder is added along with about 1 wt% of a lubricant such as stearic or oleic acid. For wet milling, 30-40 vol% of powder with 1 wt% of dispersing agent such as water, alcohol or hexane is employed.
