the purpose of the primary crusher is to reduce the rom ore to a size amenable for feeding the secondary crusher or the sag mill grinding circuit. the ratio of reduction through a primary crusher can be up to about 8:1. feed: rom up to 1.5 m; product: -300mm (for transport) to -200mm (for sag mill) feed rate: 160 to 13,000 tph
as can be seen in fig. 6b, the minerals present in the product of open-circuit mill, in the order of abundance, include molybdenite, which is mostly free and has become fine after grinding in mill
a protocol for predicting gravity recovery of platinum group minerals (pgms) in grinding circuits is being developed based on that for gravity-recoverable gold (grg) (laplante et al., 1990, banisi et al., 1991, laplante et al., 1995, putz et al., 1993, woodcock, 1994, noaparast, 1996, xiao, 2001). the protocol integrates three data sets: gravity-recoverable platinum group minerals (grpgm) in a stream, the behaviour of the pgms in the grinding circuit (cyclones and ball mills…

a study has investigated the effect of using different milling media on the ultimate flotation performance of a ug2 ore milled in a laboratory tumbling mill. the results showed that the different media required different energy inputs to obtain the same grind.
platinum group mineralogy and ffect on flotation at ldi – feeds mineralogical studies were performed on five mill feed samples taken at different times during the period. sample assays ranged from 1.56 g/t pd+pt to 3.00 g/t combined pd+pt. while the mineralogy of the five samples varied widely, broad trends were evident. a total of 444
with the magotteaux mill® calibrated, alternative grinding media are substituted into the mill for testing. the procedure determined during the calibration process for the current grinding media is then applied while grinding the bulk sample employing the alternative grinding media. in this way, it is possible to measure changes in pulp
deposits of platinum-palladium ores in the 48 contiguous states. exploration by johns-manville corp. (manville corp.) has resulted in the delineation of an approx imately stratigraphic zone (j-m reef) rich in p1atinum- and palladium-bearing sulfide minerals (1).4 the zone is
due to their relatively low energy requirements, both these mill types are also being increasingly used for secondary and tertiary grinding as replacements for ball mills [8, 9, 10]. the decreasing mineral grades in the ores have also led to increased throughput rates in the flotation stage (fig. 15).

magotteaux, market leader in the design and manufacturing of wear parts, has also become the leader for both horizontal and vertical shaft impactor applications. our multibusiness experience in crushing benefits to our customers as we offer safer and technology proven solutions to
to this end, three mono-size classes feeds 850–600 μm, 600–425 μm and 425–300 μm of a platinum ore were ground using three different ball sizes (10, 20 and 30 mm) in a laboratory mill for the grinding times 0.5, 1, 2, 4, 8, 15 and 30 min. the data collected was used to determine breakage and some of the selection function parameters.
vibrating-disc mills ts & t series. the vibrating-disc mill is used for the fast and dust- and loss-free comminution of minerals, organic and ceramic materials, herbs and spices, diverse brittle metal alloys, etc., to analysis fineness.
the vibrating mill gsm is a vibrating mill with exchangeable grinding barrels used to crush brittle and fibrous material down to high degrees of fineness. the size reduction is achieved by impact and friction inside two vibrating grinding barrels which are filled with freely moving grinding balls.

the clinker-grinding mill operated by star cement was acquired by ultratech cement middle east investments ltd. of india in 2010. this mill is capable of producing 500,000 t/yr of cement. the petrochemical plant owned and operated by gulf petrochemical industries co. b.s.c (gpic) was capable of producing 400,000 t/yr of ammonia and 600,000 t/yr of urea in 2010.
the ball mill is traditionally the basic system used for the grinding of raw material, clinker and additives in a cement plant, as well as a wide range of minerals. benefiting from a large experience, the fcb b-mill has been designed to be particularly well adapted for the grinding of products at high fineness and grinding of very abrasive products and solid fuels.
a mill of the same type has already been successfully installed at dg khan cement in pakistan and with a grinding table diameter of 7.2 m, it is the world’s largest cement mill.
the company focuses on 4 mineral ore types that represent the biggest pie of the mineral grinding space. these are iron, platinum, gold and copper. annual replacement requirement of grinding media is estimated at 2.5 million tons. of this, less than 20% is currently converted to high chrome while the balance is served by forged grinding media. this represents a large potential opportunity to convert forged grinding
