1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

A ball mill is a type of grinder used to grind or 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 cylindrical ...

Industrial Ball Mills: They are intended for usage in the manufacturing factories, where they can process the huge amount of materials at the same time. Each industrial ball mill has multiple chambers to ensure thorough grinding or mixing of materials. The added materials pass from one chamber to another to become finely ground and interlinked.

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. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.

Working: At low speeds, the ball roll over each other and attrition (rubbing action) will be the predominate mode of action. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Advantages: It can produce very fine powder. Ball mill is used for both wet and dry grinding processes.
Get priceBall mill is an idle tool for grinding many materials into fine powder and it is used to grind different kinds of row materials.There are two ways of grinding, first is dry process and second is wet process.
