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.

28-12-2012· Multi-roll machines may use rolls in pairs or in sets of three. Machines with more than two rolls are, however, rare in modern mills. The great disadvantage of roll crushers is that, in order for reasonable reduction ratios to be achieved, very large rolls
PHYSICAL METALLURGY OF A HSS MATERIAL FOR HOT ROLLING MILL ROLLS Jacqueline LECOMTE-BECKERS 1 In order to adapt to severe hot rolling conditions of a Hot Strip Mill, a rolling mill roll with much higher rolling mills with regards to strip’s surface quality appearance and for better productivity of the rolling mills.
By strictly controlling the temperature and roll surface condition, stock sheets (or Hot-Rolled Steel Sheets and Coils plates) that are easy to process are produced with flawless surface condition and internal quality. All production . line processes, starting from feeding to the reheating furnace to the completion of coiling, are controlled by a

mill operator in the way of knowledge and ability. The skill of the pellet mill operator, through his ability or mistakes, influences plant profitability. Pellet mill operators have a vitally important role in the manufacture of animal feed. They should recognize this responsibility and the great contribution they make to an efficient feed plant.
As an integral part of a modern roll maintenance program, roll grinding and balancing uses machinery with accurate inspection and measurement equipment. This paper provides practical tips on roll inspections, balancing, grinding and grooving. In addition, we discuss proper roll handling during removal, storage, transport, and reinstallation.

Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill “sees” instantaneously unless some damping system such as a surge hopper is used. Even though the feed rate averaged out over time may be within acceptable limits, the instant the surge hit the roll the feed rate
