The mill works in a dry grinding and classification circuit with pneumatic transport. ... The electromagnetic mill installation constitutes a unique setup that causes open loop instability and ...
Open loop response of the particle size control loop was recorded when sump water addition rate was altered. Loop gain, delay and rise times were measured. Following completion of the control system commissioning, a series of tests were performed to determine whether grinding circuit performance and design objectives had been achieved.
The characteristic differences between open- and closed-circuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier. For the same median diameter of the product, the rate of powder production in the closed-circuit is about 5% higher than that of the open-circuit. Contact Supplier
A conventional grinding circuit consisting of one open-loop rod mill and one closed-loop ball mill is essentially a two-input×two-output system, assuming that the classifier pump box level is ...
Semi-autogenous grinding (SAG) mill control optimisation presents a number of challenges. SAG mills have multiple inputs that are used to control multiple outputs (MIMO process). Secondly, the SAG mill loading process is a 'high inertia' process that can be approximated as an integrating process. This means that it is open-loop unstable.
The flow of the product through the grinding system may be closed-loop, where oversized meal from the screener is recycled back to the grinding mill, or open-loop, where the grinder configuration is adjusted so that no oversize particles can pass through.

the mill for further grinding. Water is added to the mill and sump to condition and control the grinding process (Coetzee, 2009) . The mill load and sump level are open -loop unstable, and must be controlled, since the mill and sump act as integrator s in the process recycle circuit (Craig et al., 1992 ). An optimal operating range of mill ...
