Automatic process control in continuous production processes is a combination of control engineering and chemical engineering disciplines that uses industrial control systems to achieve a production level of consistency, economy and safety which could not be achieved purely by human manual control. It is implemented widely in industries such as oil refining, pulp and paper manufacturing ...

The Millstar Advanced Control System has a comprehensive suite of control strategies that can be applied to provide an innovative control solution for almost any milling circuit configuration. The main goals are: • Stabilise the mill feed. • Control product quality to the downstream processes. • Optimise throughput and grinding efficiency.
We help connect independent production processes and suppliers with a distributed control system that provides a single interface to control production. And, we help you do more with less energy, from reusing centrifuge braking energy to replacing cane mill steam turbines with variable speed drives and induction motors.

The measurements provide feedback to the rolling mill control systems. The rest of the slab can then be brought closer to the desired gauge. Past the gauge house the slab enters the runout table, a flat series of rollers leading to the coiler. Several systems are aligned along the runout table.
US Steel wanted to improve the quality and reliability of steel production from its first generation hot strip mill (HSM) built in 1938. The Hatch Force Feed Forward (FFF) system provided the best value to the HSM in Irvin, Pennsylvania, with a high performance comparable to the bestinclass AGC systems.

Mar 14, 2014· Re: Coal Mill Level Monitoring Sytem for a Roller Mill 03/14/2014 10:46 AM I worked on a Milltronics ball mill control system years ago and for what I recall sound pressure was only one process variable used to measure mill load.
MILL FILL LEVEL CONTROL. Use the Mill Feed Rate to control the Mill Fill Level (rather than bearing pressure). The Mill Fill Level setpoint can be pushed to a safe maximum to optimise the throughput. Stabilize all Fill Level Signals (input, output, shell) for effective ''what goes in goes out'' operation. SAFETY CONTROL
Unlike many component systems on the market, the DCL6/10 is specifically designed for sugar mill chute level indication and transmits a 4 to 20mA signal for connection to control systems. It is extremely simple to set up and commission, with the whole commissioning .
Interface level measurement Whether measuring levels of two materials in a storage vessel or telling your control system when to separate one liquid from another, accurate monitoring helps ensure product quality and an efficient process.

The control system scheme for the milling plant section is shown in Figure No. 2 and briefly describes on the following paragraphs. The load current of the cane leveler, cane knives and unigrator indicates of the amount of cane being fed in the mill. The level of the cane chute of the first mill controls the speed of the feed conveyors.
