Read MoreJun 01 2018 In this article the effect of grinding media size distribution and feed material particle size distribution PSD on the product fineness requirements were investigated. A model free approach called the Attainable Region method was then applied in order to optimize the product size fineness in terms of the feed size and ball mix.

Media shape and mill power. The objective of this dissertation was to investigate how media shape affects grinding. Ball size distribution inside an industrial mill was analysed in terms of shapes and sizes. Load behaviour mill power and breakage as affected by media shapes were studied in a pilot laboratory mill. An inductive proximity probe ...

Media to media contact for rods mills is linear rather than point to point as with balls and are much heavier. The larger feed tends to separate rods at the feed end such that larger particles are preferentially abraded. This leads to a narrower size distribution and significantly less slime compared to ball mills.

Mill etc. 2. Grinding media The grinding media used are generally balls and cylpebs. In compartments of coarse and medium grinding are used balls and in that of fine grinding balls or cylpebs. In any compartment sizes of grinding media must be correlated with the size of the material. Between the balls are formed free spaces emptiness.
Read MoreMore hammers faster speeds and finer screens produce a finer grind. Hammer mills eliminate the need to screen product. However when you fine-grind with a hammer mill it may take more power per ton and maintenance costs may be higher compared to roller mills. Master distillers should also consider that they could overgrind or create too many ...

This test also shows that by feeding the mill with a too dilute pulp the grinding zones between the media are not saturated leading to high media wear rate. A variation in total ball angle can be detected and linked to grinding efficiency and charge expansion. This could help the operator to make the right decision and keep the mill
