Get PriceWorking Principle of Ball mill: As the mill rotates, steel balls work to grind the materials. The mill rotates approximately once every couple of seconds. The grinding system uses either 'open circuit' or 'closed circuit'. In an open circuit system, the feed rate of materials is adjusted to achieve the desired fineness of the product.

Get Price· Ball Mill Working Principle. Grinding is usually performed wet, although in certain appliions dry grinding is used. When the mill is rotated, the mixture of medium, ore, and water, known as the mill charge, is intimately mixed; the medium comminuting the particles depends on the speed of rotation of the mill and the shell liner structure.
