(PDF) Energy Efficient Ball Mill Circuit Equipment Sizing
PDF The ball mill in closed circuit with hydrocyclones is an industry standard, and well known methodologies exist for A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axiBall mill

It was found that both HPGR-ball mill and HPGR-stirred mill circuits have higher associated capital costs than the SABC option. Conversely, operating costs for the two proposed circuits are substantially lower, However, the increase in capital cost is justified economically by a reduction in operating cost attributed to the elimination of steel grinding media.

It has been shown, for example, that the replacement of a SAG mill with a HPGR in a conventional SAG-ball circuit may reduce grinding energy consumption by 15–20%. Taking into account additional savings, such as media and liner wear, it was found that a grinding cost saving of 25–35% was potentially achievable with the use of HPGRs Ball Mill. The ball mill’s basic concept dates back to prehistoric times when it was used to grind flint for pottery.

8.3.2.2 Ball mills. 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.Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.Ball Mill Principle, Construction, Working, and More Soln Pharma

Hard ore Work Index 16 = 100,000/65,000 = 1.54 kwh/t. For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tonsThe savings made in lower operation costs and lower maintenance costs are noticeable and this saving was also made in the face of a 12.5% increase in wages made when the new plant was Operating Costs of Gold Processing Plant 911
