[QUOTE="Mike678, post: 643064, member: 16778"] I have a rough sketch with sizes ,of the rod mill , that the mets. use in the lab . It is s/s 300 m.m. long and 211 m.m. i.d . I think they put in 1 k.g. of sample plus water . It is very noisy but I did have an idea of sticking some of that sound deading foam to the out side and on the ends . Just use it when the wife has gone shopping .... Running time was 1/2 - 1 hour depending on the sample . Sample ground down to less than 3 m.m. before putting in the rod mill . Rod charge , 1 off 1 inch Dia . 6 off 7/8 inch 2 off 5/8 inch 4 off 1/2 inch 3 off 3/8 inch . All s/s . Speed is important , you need to hear the rods dropping , too fast and they stick to the outside of the drum . [/QUOTE]
