The process and instrumentation or piping and Instrumentation diagram (P&ID) is probably the document most used by instrumentation and control system maintenance personnel. Instrumentation engineering. The P&ID diagram is the main and almost ideal document to synthesize all required measurement and control functions.
A 60-cm semiautogenous grinding (SAG) mill was designed for continuous wet operation in closed circuit with a vibrating screen. The circuit is fully instrumented and automated. Part of the control system incorporates Foxboro SPEC 200 controllers around the pump box to maintain level.
control is of "paramount importance to overall plant performance" in the sense that it can reduce overgrinding and therefore grinding cost and flotation losses (McIvor & Finch, 1991 ). An unstable grinding circuit operation and process can result in poor overall minerals plant performance.
Filter circuits that can be used to control the bandwidth of the system therefore play a critical role in limiting the impact of noise on a system. In fact there are four key different types of filters that are commonly used in instrumentation systems to fulfil a variety of functions. The circuits and characteristics of such filters were discussed
Grinding Circuit Control Control Strategy • Instrumentation & Control System Audit / Review • Design, Implementation & Commissioning • Training • Performance Benchmarking Keeping It Simple • Solutions are to the level of complexity that you need and that is appropriate - utilising existing control system infrastructure
Instrumentation engineers are responsible for integrating the sensors with the recorders, transmitters, displays or control systems, and producing the Piping and instrumentation diagram for the process. They may design or specify installation, wiring and signal conditioning.

This control should not be considered a grinding control but should be used by the operator to control the particle size of the cyclone overflow. Another control the grinding operator can often employ is the number of cyclones in the circuit.
