Optimization of some parameters of stirred mill for ultra
In this study optimization of some parameters of stirred mill on ultra-fine grinding of refractory Au/Ag ores was performed. A three-level Box–Behnken design combining a response surface methodology (RSM) with quadratic programming (QP) was employed for modelling and optimization of some operating parameters in ultra-fine grinding.

Optimization of the Gear Profile Grinding Process
gear grinding still increases the risk of producing grind-ing burn (Ref. 1). In order to grind gears burn-free and as produc-tively as possible a better understanding of the process is required. This is especially important for gear profile grinding due to the complex contact conditions between workpiece and grinding wheel (Refs. 2–3).
