Grinding media density. The range of specific gravity for commercially available grinding media runs from sp.gr. 1.0 for plastics to sp.gr. 15 for tungsten carbide. It makes sense that you wouldnt select a very light grinding bead for a highly viscous system or a very dense grinding bead for a low-solids aqueous suspension

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

how to define

how to define "specific power" in ball mill scale-up

Herbst et al. proposed a procedure for ball mill scale-up. It is based on linear relationship between selection function S (1/min) and specific power P/H. S= S E (P/H) Question 1: "H is the mass of the charge in the mill excluding the media" Does H represent mass of solid particles or mass of slurry? Question 2: I find 3 definitions of the

the bulk weight of grinding balls

Mar 14, 2017 In the grinding material process at ball mills becomes necessary to calculate the bulk weigh of used grinding media. The bulk weigh of the grinding balls is necessary to understand the grinding balls mass in the cube, the grinding balls mass loaded into the mill, the prevention of mill overloading with grinding balls, etc. These data often used in operational management of grinding

Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 250 microns.; The Center-Periphery Discharge mill has feed reporting from both ends and the product discharges

Thus, during calculating the grinding balls mass in ball mill (after measuring the mill filling degree with grinding media) needs to use the grinding balls bulk weight whose diameter was determined earlier. In this case, it may be differ from the grinding balls bulk weight loaded to the mill
