Obrolan LangsungThe two main functions of a mill liner consist in protecting the mill shell against wear and in transmitting the energy of the mill motor to the grinding charge to carry out the required size reduction in the most efficient way. For a mill liner, the design as well as the liner material are to be considered. The required movement of the mill charge to carry out effi-

For the additional 12 ft. lift required to arrive at 20 ft., use the pricing for extra chain per ft. of lift for model X .
Obrolan LangsungUsing slings at an angle can become deadly if that angle is not taken into consideration when selecting the sling to be used. The tension on each leg of the sling is increased as the angle of lift, from horizontal, decreases. It is most desirable for a sling to have a larger angle of lift, approaching 90°. Lifts with angles of less than 30° from

Obrolan LangsungSAG 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.

Obrolan LangsungUsually, the charge volume of SAG mills occupies between 30 and 40% of its internal volume at which the grinding rate is maximised. When the charge volume is more, then the throughput suffers. The fill level is monitored by mounting the mills on load cells. Presently, most modern mills are invariably equipped with such an arrangement.
