### Using Abrasion Index for calculating Steel Balls and mill ...

We just top up with biggest ball having 4 diameter as per calculations. But all balls gets ground till zero diameter. But when we opened ball mill after one year of operation we found that small balls below 2 diameter got deformed when we used Cast Hyper steel balls having Mn. Consumption was high. We could understand the problems.

### How to Reduce Steel Consumption in Grinding Mills

In the tumbling mills (autogenous, semi-autogenous, 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 weight/kWh is considered a better measure.

### Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

### steel ball consumption in ball mill - impactpneumatics.co.za

The power consumption and steel consumption of the ball grinding mill occupy a rather high cost ratio in the production and processing process of a cement... Optimization of mill performance by using online ball and ...

### Consumption of steel grinding media in mills – A review ...

The consumption of the grinding media represents an expressive part of the grinding operational costs; it may reach up to 40% of the costs in a mineral processing unit [19], and wear constitutes around 60% of the cost relative to ball mills [4]. ...

### Ball Mills - Mineral Processing & Metallurgy

In small milling plants, where simplicity is most essential, it is not economical to use more than single stage crushing, because the Steel-Head Ball or Rod Mill will take up to 2″ feed and grind it to the desired fineness. In larger plants where several stages of coarse and fine crushing are used, it is customary to crush from 1/2″ to as fine as 8 mesh.

### Grinding Balls & Rods - Mineral Processing & Metallurgy

Steel consumption of balls is spread out over an even greater range. Some indication as to media consumption can be obtained from power consumed in grinding. For example, balls or rods will generally wear at a rate of about 1# for each 6 or 7 kilowatt hours consumed per ton of ore.

### Predicting Steel Media Consumption - Grinding ...

A mine expending 20 to 40 million is steel balls per year may reach gains of this nature. Having a big budget for steel media consumption, based on assumptions of higher consumption, leads to complacence while the money is worn out in the mill, literally speaking.

### (PDF) A comparison of wear rates of ball mill grinding media

In ball milling, materials consumption by wear represents a very high production cost, and must be minimized by the proper selection of materials, especially those for balls.

### TECHNICAL NOTES 8 GRINDING R. P. King

steel balls in a ball mill, or large lumps of ore in an autogenous mill or a mixture in a semi-autogenous mill, as well as the slurry that makes up the operating charge. Let Jt be the fraction of the mill volume that is occupied by the total charge, Jb the fraction of the mill volume that is occupied by steel balls and E the voidage of the balls

### Ball Mills - an overview | ScienceDirect Topics

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
