Mill throughput is a key driver for maintaining profitability at Mt Keith because of the low head grade 0.5 Ni and inherently low nickel recoveries due to the mineralogical makeup of the ore. The Nickel West Mt Keith Concentrator NMK has 2 parallel grinding modules consisting of one SAG Mill and one BALL Mill per module.
Simplifying wet grinding with Metso AGSAG mills AGSAG mills are often the optimum solution for wet grinding achieved in a slurry 50 to 80 percent solids. AGSAG mills can accomplish the same sie reduction work as two or stages of crushing and screening a rod mill and some or all of the work done by a ball mill.
2018-5-10In 2010 Newmont made the decision to purchase a 42 foot ft Semi-Autogenous Grinding SAG mill from Metso and a 28 Mega-Watt MW Gearless Mill Drive GMD from ABB for the Conga Project in Peru. The test and study work showed that a single line 42 ft SAG mill.
Cascading mill a phenomenologicai design 81 that at any given time the cascading mill gives a finer distribution as the median sie of the sie distribution produced by the cascading mill is less than that of the ball mill. The difference in the grinding efficiency is more evident when the amount of production of fines is considered.
