A typical MRF uses a drum feeder to feed material into the system. These facilities then use a series of disc screeners to separate newspaper, cardboard and other papers. The separation continues with a suspended self-cleaning magnet to recover ferrous material, like tin-plated steel cans. The magnet is suspended either cross-belt (perpendicular to the product flow) or inline (parallel) above the product flow.
Grinding by use of nearly spherical shaped grinding media is termed ball milling. Strictly speaking, such media are made of steel or iron. When iron contamination is detrimental, porcelain or natural non-metallic materials are used and are referred to as pebbles. When ore particles are used as grinding media this is known as autogenous grinding.

Martian "Blueberries": In 2004, NASA's Mars Exploration Rover Opportunity discovered that soil near its landing site contained millions of tiny spheres that researchers nicknamed "blueberries." Upon analysis, they were determined to be composed of iron oxide, mostly in the form of hematite. The iron content of Martian rocks and soil contribute to its red appearance from Earth and helped it earn the name "The Red Planet." Image by NASA.
My wife and I looked at every mill American and foreign made that was available. When all was said and done country living was the one we picked. A little pricey but in the middle of SHTF this unit will not fail you. We ordered the flywheel and the corn, bean bier. First and foremost bolt this big heavy bad boy down to the counter. I built a bread table with a heavy copper sheet top. My honey bunny has everything she needs to make bead in one place. Lower part of the table has a bin for flower and a bigger one for wheat berries. Talked to a LDS family also about mills. She told us every time one of her three daughters married she gave her Country Living mill to them as a wedding gift. She said the one she has now will go to her first grand daughter when she gets married.

If you will be milling wheat (wheat berries) to make flour for bread, you will want to be sure that the grain mill (flour mill) will grind the wheat berries into fine flour.
We also love the Insir Grain Grinder Mill if you prefer an electric model. It has a 950-watt motor that can quickly produce flour and is quieter than some other electric models.
