Such mills are common in South African operations; mills are sometimes referred to as tube mills or ROM ball mills and are also operated both autogenously and semi-autogenously. Many of these mills operate at higher mill speeds (nominally 90% of critical speed) and often use "grid" liners to form an autogenous liner surface.

The sturdy and durable design of hydraulic lifts has made them popular in a wide variety of industries. The Occupational Safety and Health Administration (OSHA) and the American National Standards Institute (ANSI) have specific requirements regarding the operation of hydraulic lifts and training for operators.
However it is powered, the basic principle of lift mechanism design operation remains the same. So, using a hydraulic scissor lift mechanism as an example, the sequence is this: The scissor lift operator turns on the power source. Using a valve to control the flow of fluid or air starts to fill the cylinder(s) with hydraulic fluid (or ...
