07.03.2006· We have a client requesting a wet ball value (TXDOT TEST METHODS 116-E) or, as an alternative, an LA Abrasion Test. The problem is they don't have enough material to run either test. Are there any other tests out there that would yield similar information with a smaller sample size (6000 grams or less)? Thanks in advance for any help. RE: Wet Ball Value or L.A. Abrasion Testing .
We are using Fritsch Planetary ball milling for milling of metal powders. I am still confused about the pre- cleaning and post-cleaning of vials and balls for efficient milling to avoid contamination.
tests. Besides particle size reduction, ball mills are also widely used for mixing, blending and dispersing, amorphisation of materials and mechanical alloying [1, 49, 51]. As a construction, a ball milling device usually consists of a cylindrical vessel mounted on an appropriate basis at both ends which allows rotation of the vessel around the center axis. The mill is driven by a girth gear ...

Three types of tests are available for mill power determinations. In most cases one of two bench scale tests is adequate. First, a Jar Mill grindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hp-hr/t) to grind from the design feed size to the required product size. The second test, a Bond Work Index determination, results in a specific energy ...
