To reach the fine and ultrafine domains of particle sizes (median particle size <50 μm), Rajaonarivony et al. [3] showed in a model study using a smallscale ball mill on pine bark that impact is more energyefficient mechanical stress during the first stage of the fragmentation process whereas attrition becomes more efficient when the average ...
Either way, you need proper technology depending on the type of food, the hardness or density of the food, moisture content, and particle size you would like to achieve. Food milling equipment ranges from crushers, shredders, and granulators, to hammer, ball, and pin mills, air classifier or jet mills, and colloid and corundum mills.
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.

3. From 'artisanal' to 'smallscale' gold mining in Kamituga. Prior to 2011, all gold in Kamituga was crushed manually by workers, mainly women known as mamans twangaises, who were busy pounding the pieces of stone 5 from the pits in a mortar or on a large stone. This in turn required significant time and money to transport the stone from the production sites to the crushing site.
