Mill (grinding) Wikipedia

SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in

MINE LINERS Magotteaux

Grinding mechanisms: The rules that guide the design of a liner depend on the required grinding mechanism. Three main categories of grinding mechanisms can be highlighted: 1. IMPACT The mechanism of reducing the big rocks is "crushing" which requires impacts. Either by impacting of grinding balls on the rocks (SAG mill) or by interaction between

Grinding Mill Liners Mineral Processing &

There are basically two groups of Grinding Mill Liners. Ones with a HIGH PROFILE and those with a LOW PROFILE. The high profile liner is designed to give the media the higher lift. This type will be used in mills that are designed for primary grinding and as a result require the impact of the higher cascade. Ball mills working as the secondary portion of a grinding circuit will utilize the

grinding process and power draw of these mills. These functions of the liners tend to conflict, as designing the liner profiles to maximize liner life inevitably reduces the grinding rate in the mill [2, 3]. It is, therefore, necessary to develop a balance between the liner life time and the grinding performance.
