A successful mill shutdown can be measured by timely completion and zero harm. Removal and change out of worn liners and lifters as well as essential maintenance on existing mill lining is a job for a skilled professional team. “It is well known that using a mill relining provider can save up to 40% of downtime for scheduled mill reline works.”
Difference Between SAG Mill and Ball Mill, from the working principle, application, structure, etc. Grind and blend solid or hard materials into smaller pieces by means of shear, impact and compression.
the specific energy of the crushing section, the HPGR section and the tumbling mill section separately. Hence, for example, in the case of an SABC circuit the total specific energy of the entire comminution circuit will be predicted plus the individual specific energies of the primary crusher, pebble crusher and combined SAG/Ball mill stages.
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.

Professional development as Project Engineer Steel Lining. - I elaborated works in the Steel Mill Lining and Steel Crusher area; I developed Steel Liners projects to Sag Mill, Ball Mill, Rod Mills, Primary Crusher and secondary Crusher.
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.

• Can be easily retro-fitted to existing mills. The optimal performance of AG/SAG mills is the key to successful plant operation. All AG/SAG mills using radial or curved pulp lifters suffer from inherent material transport problems such as slurry and pebble pooling, which decrease throughput and increase energy consumption.
I am more concerned about the cases where the center of mass of mill shifts to a new position, thus causing extra torque and more power consumption. Generally, it happens when you have coarse and/or hard ore going to the SAG mill, its center of mass shifts to a new position and mill drive consume more power because of the extra torque generated.
