Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the cross-section of the balls charged to the mill. With this in mind, it is interesting to make a qualitative comparison of the ball size distributions which should be generated by 76 mm pearlitic carbon steel balls versus 76 mm martensitic alloy steel balls in the 2.93 m mills.
The optimum ball size distribution is thus determined by the amount and combination of grinding balls of different diameters in the make-up charge. Grinding media wear caused by the abrasive milling environment necessitates a periodic charging of new grinding balls.
Studies also revealed that grinding media size, particle retention time, and pulp density are Keywords: coarse grinding circuit, ball mill, process optimization, chromite Comminution is a critical process in mineral processing which strongly ..
SAG is an acronym for Semi-Autogenous Grinding. SAG mills are autogenous mills but 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.
Grinding media wears and reduces in size at a rate dependent on the surface hardness, density and composition of the ore. Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter.
Most mills used in mining rely on impact to breakdown rock to a suitable size for downstream processing. The impact can be rock on rock such as in an Autogenous Grinding (AG) mill, rock and a small ball charge (~10%), used in Semi Autogenous Grinding (SAG) mills, balls of various sizes in Ball Mills and less commonly these days, steel rods in Rod Mills.
