Semi-autogenous mills or sag mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. often used in grinding at modern mineral processing plants, sag mills reduce the material directly to the desired final size or prepare it for the following grinding.
Autogenous mills operate, mechanically, similar to the ball mill. they differ in the media they use to break or grind the ore. autogenous mills use large particles of ore instead of steel or other balls for grinding media. autogenous mills use large pieces of ore as grinding media. the grinding is facilitated in autogenous mills by attrition.
Rely on our proven track record of sag and ag mill superiority. since the early 1980s, we have been designing and manufacturing semi-autogenous sag and autogenous ag grinding mills under the fuller-traylor brand. semi-autogenous grinding uses a minimal ball charge in the range of 6-15 while autogenous grinding uses ore.

Autogenous grinding mechanisms. hpgr, similarly, are generally tested with roller or piston press, to represent compression breakage. by opposition, the jkmrc approach to autogenous mill characterisation was to separate impact and abrasion mechanisms into two different tests drop-weight and abrasion tests. equally important is the need.
Discussion on aspect ratio. if the aspect ratio is low, then the limit of mill size is encountered, leading to a dual grinding line operation which may be less attractive than a single line sab or sabc operation. therefore if the ore is not overly grind sensitive, and the application is suited to a single mill scenario, sss appears.
Smelting ore mz autogenous mill can be divided into two types dry and wet , according to the different way of grinding ,which can also be called a gas falling mill and falling mill. nowadays in china, the wet autogenous grinding machine is widely used. the most special point of smelting ore autogenous mill is that it can put the original ore.
