Cement Kilns Size Reduction and Grinding

The standard mill had a diameter of 54 inches, and the hundreds of mills installed rarely varied from these dimensions. In processes such as cement milling, where the particle size has to be reduced about a thousand-fold, the product-sized particles produced in the early part of the process impede the grinding of the rest, and will tend to
