A hammer mill is typically good for grinding softer materials with Mohs hard-ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding

maximize this rate. The mill grinding efficiency can also be calculated by taking the ratio of the mill grinding rate over the material's grindability as measured in the lab. Mill percent solids optimization has thusly been achieved (McIvor et al., 2000). For media sizing, maximizing the mill grinding rate on a given ore is equivalent

> Mill throughput and efficiency gains are iterative over time > Mill trajectory modelling based on bar heights, angles, spacing and speed is very predictive > Field trials are the acid test - operator, designer and vendor > Optimisation strategy: – Maximise impact grinding AG/SAG mills – Avoid impact on the shell rather the toe of the charge

grinding mills (ball, SAG etc), fine grinding bead mills have a stationary shell, and a rotating central shaft with some form of mixing elements that agitates the beads. The design of the mixing elements varies with proprietary design (Jankovic 2002, Radziszewski and Allen, 2014, Rahal et al., 2011):

Mill related stress model The grinding behaviour of a mill is determined by • the type of stress (e.g. impact or compression and shear) • frequency of strokes or stress events →stress frequency, SF M • the energy made available at each stress event → stress energy, SE • From stress frequency the total number of stress events can be

Polysius grinding mills can be of the overflow type or of grate dis-charge design. In 1976 Polysius adopted the design of shell-supported grinding mills using slide shoe bearings. Since this time, the design has been perfected based on the experience of more than 180 units operating all over the world in various industries. Today Polysius ...

Semi-autogenous grinding (SAG) mill liner design and. · Shell lifter design is critical to good mill performance. The important process objectives in SAG mill shell lifter design are: • to provide the key between the mill charge and the mill shell for charge motion, • to maximize the rate of delivery of thrown grinding media at the toe of the charge to gain the best milling action,
