• ### SAGMILLING.COM .:. Mill Critical Speed Determination

Mill Critical Speed Determination. The Critical Speed for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell.

• The measurement of the ball charge volume load (or filling degree) is essential to maintain the absorbed power of the mill and consequently the mill production. The most common way to evaluate the filling degree is the measurement of the free height inside the mill (vertical distance between the top of the charge and the lining in the mill axis).

• ### Mill (grinding)

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 diameter, powered by a 28 MW (38,000 HP) motor.

• ### Specific surface area

Specific surface area (SSA) is a property of solids defined as the total surface area of a material per unit of mass, (with units of m 2 /kg or m 2 /g) or solid or bulk volume (units of m 2 /m 3 or m −1). It is a physical value that can be used to determine the type and properties of a material (e.g. soil or snow).
