#0183;#32;ABSTRACT: A heat treatment process of high chromium cast iron grinding media with trace alloying elements Mo, V, NB was studied. The heat treatment processes of quenching at 980 #176;C, tempering at 400 #176;C and 600 #176;C was adopted.
Highchrome grinding media have been used for During the production of grinding media the two most ing media has a direct effect on the grinding process. Helios :: Grinding Media. Cast high chrome grinding media is manufactured by casting process and subjected to closely controlled heat The manufacturing process and production
Superior grinding performance HighChrome media combining a martensitic structure with hard chrome carbides provides the optimum wear resistance against abrasion and corrosion. Our strong expertise is enabling us to select the right alloy to fit your application and minimize the costs. Steady milling conditions due to low wear rate
#0183;#32;Improved flotation performance has been achieved in test work using highchrome grinding media as opposed to carbon steel media. The inclusion of a splitcleaner flotation circuit configuration, in which the fastfloating fraction is treated in a cleaner circuit separate from the medium and slowfloating fractions, resulted in improved PGE, copper and nickel recoveries and concentrate
steel grinding media for both SAG and ball mill customers.. key global copper, gold and iron ore mining. paper entitled The use of high chromium content. Once Century agreed to trial high chrome grinding media, the plant. With the Magotteaux Mill#174; calibrated, alternative grinding media are substituted into the mill for. Read More.
reduction in the corrosion rate of the grinding media is supported by the EDTA extractable iron data. Figure 2 clearly shows that the percentage of EDTA extractable iron in the rougher feed decreased from per cent for the forged steel case to per cent when grinding with highchrome grinding media in the primary ball mill. 400300

HIGH CHROME CAST STEEL BALLS Silicon Nitride Balls are very highcost grinding media that are used for milling same materials (silicon nitride ball to mill silicon nitride materials) to avoid contamination. They are now available in 2mm and 3mm and sizes up to 25mm.
31. High chrome grinding media typically has a higher wear resistance than forged steel grinding media, but may be more susceptible to breaking. They are typically used in smaller sizes than forged steel grinding media (under 100mm).They are also more expensive than forged steel grinding media
High Cr media for primary grinding will typically contain maximum levels of eutectic carbide (30 35% by volume) and are heat treated to their maximum hardness (HRC 65 68). However, not many high Cr balls are used in primary grinding because the improvement obtained in wear resistance relative to steel, typically 25 30%, is not enough to offset Its higher cost.
There is no standard solution for mineral industry and wear rate of grinding media varies from mine to mine, ore to ore and even for the same ore time to time. Different alloys are recommended depending on ore type and mill particulars in order to arrive at the most cost economic solution.
