Ball mill transport index control strategy. A simple ratio controller was implemented to regulate the solids content in the mill by manipulating the feed water. A calculated percent solid index is used to monitor the transport in the ball mill. A separate study was initiated to develop a measurement of this property (Bascur, 1985).
Gate Valve vs Ball Valve Working Mechanism. A gate valve employs a gate to control the medium flow. Gate is a solid disk that is connected to a stem, acting as a barrier. Gate valves are commonly operated by an actuator, handwheel. The actuator is connected to a valve stem and transmits rotational energy to it.

Types of valves with PID symbols. A valve is an element in a piping system that regulates the flow. A rotary valve turns only at 90°. Linear valves operate when the stem is vertical, and the packing box is above. Selfactuated valves keep setpoint pressure in pipelines within predetermined ranges.
For ball mills, the installation is not considered generally necessary, however the installation of above instruments can avoid occasional tripping due to jamming of rotary gates at mill inlet due to metallic debris from various origins as well as helps to reduce metallic nibs accumulation in mills, which disturbs mill operation and mill ...

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
