Jun 22, 2018· The ball milling method consists of balls and a mill chamber. A ball mill contains a stainless steel container and many small ball made up of iron, hardness steel, tungusten carbide, or .
Bond ball mill work index (S dBWI) grindability test to provide the total pinion energy at the specified grind size for mill design purposes, herein reffered to as micro ore hardness. The full SAGDesign test produces the SAG grindability (W SDT) and the Ball Mill grindability (S dBWI) both in kWh/t, as well as the ore specific gravity.
Overview. The ball mill for clinker is an efficient tool for fine powder grinding. It is mainly used to grind the clinker and raw materials in cement industry and also can be applied in metallurgy, chemical, electric power and other industries to grind all kinds of ores.
Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.
zIt was additionally shown that the ballmill dimensions predicted from the above methodology are almost equal to those of the Bond method. This fact is very important, because the various corrections, associated with the Bond methodology, are not necessary and the model developed can be used as an alternative method for ballmill scaleup ...
