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 Based on our world wide experience AIAE can help select optimum alloy for specific application ranging
Copper silver and gold are in group 11 of the periodic table; these three metals have one s orbital electron on top of a filled d electron shell and are characterized by high ductility and electrical and thermal filled d shells in these elements contribute little to interatomic interactions which are dominated by the s electrons through metallic bonds
Especially as the third generation of anti wear Alloy High Chromium White cast iron developed successfully The impact energy is 5j / CM2 the impact toughness is very good the breakage rate of the grinding ball is less than 1% 3 The ore consumption is kg / ton compared with kg / ton of forging ball After reasonable matching of all elements ratio casting qualified grinding
The grinding media may be the ore itself autogenous grinding bars balls or cylpebs or even the ore itself together with a small amount of balls semi autogenous grinding A survey found out that approximately 53% of the grinding circuits around the world use ball mills and 38% use autogenous or semi autogenous grinding and therefore nearly 90% of mining operations are users of balls

The ball mill is a key piece of equipment for grinding crushed materials and it is widely used in production lines for powders such as cement silicates refractory material fertilizer glass ceramics etc as well as for ore dressing of ferrous and non ferrous metals The ball mill can grind ores and other materials wet or dry There are two kinds of ball mills according to their ways of
As an example a large ball mill processing 50 million tons of ore per year has a down time cost of about 300 000 USD per hour [42 43] The typical average downtime for a maintenance term is about 20 h For a SAG mill plant processing 50 million tons of ore annually the benefit of a 10% extension of grinding ball lifespan causes only a % increase in alloy cost but saves over
Iron Ore Pig iron grinding steel ball coke and limestone are the main raw materials in the steel making industry Product Classification/Uses IRON ORE IRON ORE Iron Ore is the primary raw material in the manufacturng of steel Steel is an alloy consisting mostly of iron and less than 2% carbon Iron ore is therefore essential for the production of steel which in turn is essential in
At high temperatures zinc present in such ore turns to vapor and permeates the copper thereby producing a relatively pure brass with 17 30% zinc content This method of brass production was used for nearly 2021 years until the early 19th century Not long after the Romans had discovered how to produce brass the alloy was being used for coinage in areas of modern day Turkey This soon
