The rougher concentrate is reground in an IsaMill, which is a stirred mill that operates with inert silica sand grinding media. For this project, Anglo Platinum required a stirred mill of a unit size not previously available. Xstrata Technology and Anglo Platinum collaboratively developed the
The stirred media (ball) mill is less effective at the start but keeps on going. In general the rule of making nanoparticles from large particles is "Don't even bother to try". The only exception is if the large particles are agglomerates in which case there is some modest hope of success.
Stirred Media Detritor (SMD) is a fluidized, vertical stirred mill designed for optimum grinding efficiency for fine and ultrafine grinding products. SMDs have the capacity to operate continuously at full load power draw with no steel contamination of the product. They are suitable for both open- and closed-circuit operation.

economical grinding media; initially low-cost media have been employed—sized silica or river sand and granulated furnace slag. This is now becoming more uncommon, with ceramic grinding media of various compositions being generally employed. Efficiency of operation, stirred mill type, and quality control are important factors in this
(1) Vertically oriented jet mill with tangential grinding nozzles located at the bottom and static classification occurring at the top. Capable of grinding dry powders to 1-50 micron averages, this vertical jet mill produces a narrow particle size distribution, consumes less energy and is easy to feed with a wide variety of materials.
Grinding media can be furnished as either flint pebbles or high density ceramic balls (3.4 sp. gr. same as ceramic lining brick). DRY GRINDING BALL MILL. Complete laboratory testing service, mill and air classifier engineering and proven equipment make possible a single source for your complete dry-grinding mill installation.
activation of zeolite and kaolin in stirred media mill in various media, wet and dry state from energetic and mechanochemical point of view. MATERIALS AND METHODS The wet and dry grinding experiment was carried out in a batch horizontal stirred media mill equipped with a high-wear-resistance (Al 2 O 3) liner and stirring discs.
These stirred mills are charged from the top or bottom and the product discharged either from the top end or from the bottom end after passing through a screen that separates the grinding medium from the ground particles. The screens may be flat or cylindrical so that they may be easily removed.
The best strategy is to use coarse grinding media for coarser feed material and fine media for finer materials to optimize energy efficiency of the stirred media mill. Another possibility is to employ pregrinding with coarse media followed by …
