Ball mills are a fundamental part of the manufacturing industry in the USA as well as around the world. Ball mills crush material into various sizes and extract resources from mined materials. Pebble mills are a type of ball mill and are also used to reduce the size of hard materials, down to 1 micron or less.
Iron balls like these were and still used by "ball mills" to crush mined ore. A large drum is filled with ore and iron balls and then tumbled to pulverize the ore to powder (part of the reduction/ refining process). Here in Colorado a lot of these are mistaken as "cannon balls", however most are left over from the mining days.
Vertical mill is used in grinding material at smaller particle sizes, which is used after ball mill. Pebble mill is used when product contamination by iron from steel balls must be avoided. Fluid energy or jet mill consists of a hollow toroid. A fluid, usually air, is injected as a high-pressure jet through nozzles at the bottom of the loop.
