A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow.
Smaller capacity for each mill means a better degree of combustion flexibility. They require periodic roller changes as they wear out during pulverizing, increasing the maintenance cost. Harder coals require this type of pulverizers. 2. Impact and Attrition Type. Coal is fed into a rotating cylinder containing steel balls of around.
