A survey of 40 industrial mills in China found that the maximum ball mill diameter in use was 7.9 metres and length 13.6 metres. Autogenous mills range up to 11 metres in diameter. The length-to-diameter ratios indicated in Table 1 for ball mills are for normal use, but for primary grinding the ratio could vary between 1:1 and 1.8:1.
Practical 1 : Ball Milling | TF Lab 1
Introduction: '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.

Introduction to Milling Tools and Their Application
Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket. The most common options are 2, 3, or 4 flutes.
