Cement grinding Vertical roller mills versus ball mills
As less grinding energy is used in producing a cement of a required fineness in an OK mill and the retention time in the mill is shorter, the product will not be heated up as much as in a ball mill. This means that a lower degree of dehydration of the gypsum must be anticipated. This may not be a problem if the gypsum is sufficiently

Practical 1 : Ball Milling | TF Lab 1
'Ball milling is a method used to break down the solids to smaller sizes or into a powder. A ball mill is a type of grinder which consists of a cylinder. It is used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. The cylinder rotates around a horizontal axis.
