### Cement mill notebook SlideShare

Jan 07, 2015 The main influencing factor on the retention time is the mill length. Therefore, the ratio of length to diameter (L/D) of a mill is an important factor for an optimal design of the mill. L/D = 3.0 3.6 for closed circuit.

### Influence that Ratio of Length to Diameter of High

100mm diameter and 200mm length. However, in some cases, high-strength concrete structure members are thinner than specimen’s length. It was because that the bar arrangement is different or sometimes drilling core specimens are accidentally sawed short with small length-to-diameter ratios. It would be resulting in high values of

### Ball mill

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
