1.Ball mill: the grinding medium is mainly short steel bar or steel ball.The grinding force of ball mill is large, the structure is light, and the rotation speed is stable.

Macsalab rod / ball mill vessels are available in grade 304 and 316 stainless steel, rubber - lined mild steel as well as ceramic (alumina).

Quality: the quality factor is one of the major points one needs to consider while buying industry equipment.If this factor is overlooked, the buyer may land himself up in much trouble.In case the quality of the ball mill is not of good quality, it will be not able to deliver the desired result.The buyer then has to get it repaired if not replaced.In both cases, he has to waster money and time.Hence, it is always suggested to buy superior quality product to have the best service of the equipment for a long time.

Although the working principle of different types of ball mills is the same, making use of the collision and grinding between the medium and material to achieve ideal product size, the model selection of ball mill differs in individual demands.When investing in the ball mill grinding production line, one not only needs to understand the nature of the raw materials but also take the discharge and output requirements as well as the working environment into consideration.

For example, the 100-150 tons ball mill has a maximum ball loading capacity of 9.5-10 tons.For the first time, 30% 40% of the steel balls (120mm and 100mm), 40% 30% of the medium balls (80mm) and 30% of the small balls (60mm and 40mm) were added.Why only 80% of steel balls are added in the running in process of the ball mill? because after the ball mill is installed, the large and small teeth of the ball mill need to mesh, and the handling capacity (ore volume) should be gradually increased.After two or three days of normal continuous operation of the ball mill, stop the ball mill and check the meshing condition of the large and small gears.When everything is normal, open the manhole cover of the ball mill and add the remaining 20% steel balls for the second time.

The rod mill is generally more efficient than the ball mill due to its more effective cascading action and the greater bearing surface offered by the rods.This means it can operate at lower speeds and with less grinding agents and producing less undesirable slimes byproduct.Rod mills do, however, require more attention during operation to prevent rod tangles and are generally ineffective at dry milling operations.They are also limited to a maximum rod length of approximately 20 feet (6 meters) which means they are generally smaller than ball mills.Rod mills also exhibit more liner and lifter wear than other mill types due to the comparatively high weights of the rods.

Dove ball mills are made of high grade cast and carbon steel for extra strength, long and trouble-free operations.

After the first stage crushing process, the ore material enters the double-layer vibrating screen, the crushed upper layer material with middle layer material enters the second crushing stage, the outlet material from the first crushing stage and the second crushing stage into the screening procedure.The screened material is ground by the first stage ball mill, a closed circuit grinding system is composed of the ball mill and the classifier.The staged overflow is classified by the cyclone and then enters the second-stage ball mill for re-grinding, and then forms a closed-circuit grinding with the cyclone.The gold-plating equipment cyclone overflow firstly performs preferential flotation, and the foam products are subjected to secondary selection and a three-time selection to become concentrate products.After the preferential flotation, the tailings undergo a rough selection, a selection, and two the selection process of three selections, three selections, and one sweeping, one selected tailings and one sweeping foam product enter the cyclone for re-classification, re-selection, secondary selection and one fine the selection constitutes a closed-circuit selection, and the three selections and the second selection constitute a closed-circuit selection.

Like earlier suggestions for mills for cutting wood, i recommend that you stick to 2 flute ball mills with a moderate helix angle of 30 degrees or a little less.At normal cutting speeds (ipm or inches per minute) on the level of cncs that might be found in most digital woodworkers shops, this configuration gives the mills enough time to efficiently cut and eject waste before the bit overheats.As previously recommended, theres value in getting millsthat are made out of carbide.I regularly do 3d carving runs for several hours at a time and have found carbide adds to longevity and is worth the extra cost.

The grinding ore will be discharge through the discharge port, and then the discharged mineral will be classified into the qualified product in a spiral classifier, with the coarse sand being returned to the ball mill through the combined feeder to continue grinding.

The ore milling process: following grinding in the ball mill, the material is returned via the sump to the secondary hydrocyclone for resizing.The trash screen removes wood from the old workings that may have found its way into the processing circuit.The slurry that remains after this process has a very fine particle size.Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand).Such a fine particle size is required for gold liberation the size required for the cyanide to be able to 'see' the gold in the leaching process.The remaining slurry passes through a pre-leach thickener, to remove some of the water.The recovered water is reused in the grinding circuit while the thickened slurry moves into the leaching circuit.
