Ore is crushed in-pit, in three semi-mobile gyratory crushers. Overland conveyors feed two secondary crushers, and two mill trains each consisting of a 40 foot diameter 28 megawatt SAG mill twinned with a 44 foot length 22 megawatt Ball mill. The grinding mills are amongst the largest of their type currently operating in the world.

2020-4-29 The refining process can be also carried out by means of a ball mill, i.e. a double chamber roller used for heating and cooling, inside which steel balls are moved by a central shaft equipped with special arms or disks. Ball mills are used to produce cream spreads, anhydrous pastes for the production of ice cream, pralines and soft chocolates.

2009-6-3 1 Chapter 17. Processing of Metal Powders 17.1 Introduction This chapter describes the powder metallurgy (P/M) process, in which metal powders are compacted into desired and often complex shapes and sintered (heated without melting) to form a solid piece. This process first was used by the Egyptians in about 3000 B.C. to iron tools. One of its first
