Coal Mill Shanghai TON Company

2021-6-24  In an open circuit system, the feed rate of coal is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer ones and sent back for further grinding. When final products reach the fineness standard, they are discharged out of the mill.
