The Intelligent Mill Liner Bolt. Up until now, SAG mill operations have lacked the means to intelligently determine mill liner replacements, other than the "blind" option of shutting down production, clearing the feed chute and doing a full, physical inspection of the mill lining and its wear depth.

Motor characteristics are frequently given as two points on this graph: The stall torque,, represents the point on the graph at which the torque is a maximum, but the shaft is not rotating. The no load speed,, is the maximum output speed of the motor (when no torque is applied to the output shaft).

· Valley Forge has recently developed a liner bolt innovation to improve the reliability of mill liners and liner bolts in ore grinding mill applications. Recently, concern has been raised about liner breakages triggered by stress concentrations found at the base of the liner pocket where contact is typically made with the bolt head. Liner bolt customers have also reported problems of 'racing ...

The starting torque characteristic of this type of ball mill is not linear. Figure 2 shows the graph of mill speed versus torque requirement: Figure 2 The graph clearly shows that the torque requirement exceeds 120% at 80% speed. This is why the starting torque of the drive motor should be at least 130% of full load torque.

· Torque and Horse-Power are the twin outputs of an engine. They are related and proportional to each other by speed. The ' torque-band ' in an engine curve represents its pulling ability which determines a vehicle's ' driveability ' & ' acceleration '. Torque is most needed while moving a vehicle from the stand-still and/or climbing a slope.

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.
