Cement mill - Wikipedia

A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel. The smaller grades are occasionally cylindrical ("pebs") rather than spherical. There exists a speed of rotation (the "critical speed") at which the contents of the mill would simply ride over the roof of the m…

Inefficient grinding conditions prevail especially in the second compartments of multi-compartment cement grinding ball mills. Thus, energy efficient grinding mills such as high pressure grinding rolls (HPGRs), vertical roller mills (VRMs) and Horomill® etc. are introduced and integrated to the cement grinding circuits to reduce the specific energy consumption of cement grinding. HPGRs are ...

Cement grinding Vertical roller mills versus ball mills

today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits ...

At the same time, the steel balls are carried to a certain height and then fall to grind …

Energy efficient cement ball mill from FLSmidth

In our two-compartment cement mills, the first compartment (for coarse grinding) has a step lining suitable for large grinding media. It protects the shell while ensuring optimum lifting of the mill charge. In the second compartment (and also in our one-compartment cement mills) we use a corrugated lining designed to obtain the maximum power absorption and grinding efficiency. For special applications, we can supply a classifying shell lining for fine grinding in the mill.
