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 .
A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. The grinding media are the balls, which may be made of steel (chrome steel), stainless steel, ceramic, or rubber. The inner surface of the cylindrical shell is usually lined with an abrasion-resistant material such as manganese steel or rubber lining. Less wear takes place in rubber lined mills. The length of the mill is approximately equal to its diameter.
The general idea behind the ball mill is an ancient one, but it was not until the industrial revolution and the invention of steam power that an effective ball milling machine could be built.
This kind of ball mill consists of several parts including fillings entrance setup,main bearing,rotary part.transmission part, gear cover and so on. The tube which equipped with anti-friction sheathing board inside is welded of rolled steel plate. There is a hole on the tube for the use of the maintenance worker can get in and out to maintain or repair the machine.
When the tubular body is rotating,the fillings and grinding medium is brought up to a certain height by the tubular body, and then they fall down or roll down freely from the wall of tubular body.The grinding of ores grinding ore to powders by wallop made by falling grinding medium and its grinding and peeling activity.
