effective inner diameter of the mill

US3404846A

the lifter must be something more than a mere roughening of the inner surface or lining of the mill. The probable minimum height for a mill of 5-foot diameter would be of the order of 3 /2 inches. It should be kept in mind that as the mill increases in even ...

Machining Hole-making Process, Opertaions, Tools, Machines

A custom tool can be created to machine a non-standard diameter, but it is more cost effective to use the closest standard sized tool. Tolerance - In any machining operation, the precision of a cut can be affected by several factors, including the sharpness of the tool, any vibration of the tool, or the build up of chips of material.

Ball mill

The inner surface of the cylindrical shell is usually lined with an abrasion-resistant material such as manganese steel or rubber lining. Less wear takes place in rubber lined mills. The length of the mill is approximately equal to its diameter.

For non-standard sizes, the hole must be machined using an end mill tool, potentially increasing the cost. Also, limit the depth of all holes to 4 times their diameter . Deeper holes (up to 10 times the diameter) can be manufactured, but they will likely increase the cost, as they are problematic to machine.
