ball consumption in iron ore grinding

ball consumption in iron ore grinding. How to Reduce Steel Consumption in Grinding Mills,In the tumbling mills autogenous semiautogenous rod and ball wear is generally expressed in terms of steel consumption per ton of ore ground or per kWh consumed by the mill When comparing the wear rate of different ores in different types of mills unit weightkWh is considered a better measure...

Cast Grinding Steel Balls 911Metallurgist

In magnetic iron ore grinding, the silica levels are continually being decreased from crushing to rod milling to ball milling by intermediate concentration steps. Subsequently, the wear environment becomes progressively less abrasive. Meulendyke, Moroz, and Smith (1987) reported that it is in the low abrasive environments where the corrosive component of wear can become quite significant. In

efficiency by increasing the poser losses, oil consumption, and rate of component replacement. Wear may define as the removal of material from solid surface as a result of mechanical action. It is a characteristic feature of the wear process that the amount of material removed is quite small.. In the case of grinding of different ore minerals factors that affect ball wear can be summarized

Heat treatment process for high chromium grinding ball

The heat treatment process of high chromium cast iron grinding ball includes wind quenching, oil quenching, and special quenching solution treatment. After repeated test and mining, the oil quenching can fully meet all its technical specifications The consumption of iron ore is twice that of iron ore. The heat treatment process is the use of two-stage heat quenching and low-temperature

Grindability Studies of Mineral Materials of Different

and iron ores samples were ground using a ball mill in different grinding conditions (dry and wet) and at different critical speed (R 45%, R 70% and R 90% ) during wet grinding. Results are compared considering the relative impact on particle size and shape. Materials were ground in a lab scale ball mill for 2hours with steel balls and size analysis of products were carried out using different

Pellet feed grinding by HPGR ScienceDirect

15/3/2015· At present, HPGRs are (still) applied in combination with ball milling, either as a pre-grinding stage or as a regrinding of the ball mill discharge in integrated milling-pelletizing plants (Van Der Meer, 1997, Saralaya et al., 1997), Also, HPGR is applied to regrind mixtures of ore concentrates bought from different sources in stand-alone pellet plants. In addition, HPGR is applied as

More efficient grinding for Iron Range industries

3/6/2020· Unlike rod or ball mills, high pressure grinding rolls reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other. There are no rods or balls that need replacing and it reduces energy consumption by about 40 percent for certain ore types. It also substantially reduces water

A discussion on the measurement of grinding media

1/7/2016· 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
