Coal preparation plant Wikipedia

Control and instrumentation is a very important part of a CPP. Measurement of flow, density, levels, ash and moisture are inputs to the control system. PLCs are used extensively in plant design. SCADA systems are typically used to control the process. Other instrumentation found in plants include density gauges and online elemental coal analyzers.
