Ball mill - Wikipedia
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

Boilers
Pulverized coal boilers fire finely powdered coal, typically with an average particle size of about 25 µm (0.001 in). Coal burns in suspension, like the combustion in an oil- or gas-fired boiler. Coal is pulverized in some type of large mill Pulverized coal is fired out into the furnace volume using burners that look somewhat like oil
cement - Extraction and processing | Britannica
cement - cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
