Effects of two stage austempering Heat treatment

Wear conduct of Austempered Ductile Iron (ADI) balls in the grinding of iron ore in a ball mill process was examined as a function of microstructure developed by carrying out 2-stage asutempering heat treatment. Various microstructure of ADI are produced by austenitising SG (spheroidal ghaphite) iron balls at 9200 C for 60 minutes of time and given step austempering heat treatments those

Iron Ore Processing for the Blast Furnace

Most of the material continues to be finely ground in one of five secondary ball mills, which are powered by electric motors ranging from 2,500 hp to 4,000 hp and are charged with 1-1/2" chrome grinding balls. Fine grinding is achieved using these smaller mills, bringing the ore to a similar grind as that found in face powder. The screen undersize is then moved to hydroseparators, where silica

Stainless steel grinding balls for mining / ball mill

Grinding balls for mining are generally used to break down secondary materials such as rock, cement and stone during the extraction of ores and metals. AISI steel grinding balls for ball mill applications typically have a tolerance of ±0.05/±0.10 and a density of 7.70 to 7.95. Exceptions include Al series 1XXX and Al 6061 which have the same tolerance but a density of 2.71 and 2.70

Ball Mill - an overview | ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones. The cyclones send correct-size material on to flotation

Energy Consumption in Mining Comminution

Crushers are the first stage of ore processing. Depending upon the application, power can range from 180 kW (240 HP) to 1200 kW (1600 HP). Rocks as large as 50 cm in diameter are reduced to 15 cm fragments [11, 13] which are then reduced to fine particles in SAG (Semi-Autogenous Grinding) or Ball mills.
