Milling. Milling is a crucial step in post production of rice. The basic objective of a rice milling system is to remove the husk and the bran layers, and produce an edible, white rice kernel that is sufficiently milled and free of impurities. Depending on the requirements of the customer, the rice should have a minimum number of broken kernels.
A hammer mill is typically good for grinding softer materials with Mohs hard ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi als become very abrasive therefore, they are not suitable for high speed hammer mills. In a typical jet mill, grinding.

For most materials you will be grinding, a 25 material charge (relative to jar volume) is the ideal load. There are some exceptions to this, such as when milling fluffy mixtures containing a lot of air. The volume of a high charcoal mix tends to be inflated before grinding due to a large quantity of air trapped in among the light charcoal.
