A new laboratory test was conducted with torque mill considering a 15% ball charge level that was determined by simulation. Table 4 presents the energy specific selection function parameters obtained with 15% ball charge level. A new simulation was performed with the new energy specific selection function parameters, presented in Table 4.
The SAG mill trommel undersize is combined with the ball mills’ discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed to the flotation circuit. The designed ball milling circuit product is 80% passing 150 µm.

The industry best in energy-efficient grinding, the OK Mill uses five to ten percent less power than other vertical roller mills and 30 to 50 percent less energy than conventional ball mills. Easy operation and maintenance. Worn roller grinding surfaces can either be replaced or re-welded inside the vertical roller mill.
The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media, as well as a lot of noise. Most of the energy useless lost during ball mill operation, leading to low it efficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.
Simulation Ball Mill DEM SPH DEM-SPH Coupling Abstract A deeper understanding of the milling operation of ball mills helps mineral processing engineers to control and optimize them, and therefore, reduce their consuming power. In this work, the milling operation of ball mills is investigated using two methods, i.e. DEM and combined DEM-SPH.
The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the ...

Ball Mill and Grinding Circuit Preparation for Start-UP The following items must be checked before the equipment in the Grinding Circuit is started. Check the ore slot feeder for obstruction or hang—ups. Check the ball mill belt feeder for undue buildup of material. Check oil level in ball mill lube oil tanks. Also, check grease level in the mill ring gear spray lube drum. Ensure that the ...
An essential variable to efficient ball mill operation is the drum rotation rate. Snapshots of flow behavior at ten revolutions for three different rotation rates are shown in Fig. 17, with all other parameters held constant. The difference in the flow behavior of the particles is vast, as expected.
Wild feed rate fluctuations are eliminated, resulting in smoother downstream operation. Even though production was dramatically improved, the product size of the secondary ball milling was reduced and recovery increased. The results in SAG-Mill line 2 are even more dramatic.
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of 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 rotati

Ball milling is one of the few unit operation that improves with increasing mill diameter. If acceptable results can be obtained with a 12” jar mil, then good result will certainly be obtained with a 72” diameter mill. Of course there is the possibility of over milling, obtaining a different particle size distribution or a need to change ...

Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
