The dry feed of a ball mill circuit is 300 t/h. The power at the pinion of the ball mill is 1800 kW. F80 = 80% passing size of the circuit feed, in microns = 2500 um. P80 = 80% passing size of the circuit product, in microns = 225 um Solution. Work Input (Energy input): W= (1800 kw)/ 300 t/h=6.0 kwh/t. Then. WI = Work Index of this circuit

QM-3B High Speed Vibrating Ball Mill is a smallsized instrument used for making samples slightly with rotary oscillation and 3-D vibration in a laboratory. With a higher hit energy than other ball mills, it combines small volume, light weight, high efficiency, with competitive pricing, applicable for material milling and mixing.

Through the application of many scientific research and enterprise units, it is proved that the QM series planetary ball mills manufactured by our plant have a granularity of grinding materials fully meeting nano level, which has already reached up to about 30 nano (0.03 um) according to feedback of users.

Bond Work Index - an overview | ScienceDirect Topics. The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing 3.36 mm (6 mesh) to product size in the range of 45-150 µm (325-100 mesh), thus determining the ball mill work index (Wi B or BWi).

Noise The noise of belt-driven ball mill is 66dB and that of gear-driven ball mill is 68dB at no load; and the noise of the two ball mills at full load is 75dB. 6. Rational speed ratio: The rational speed ratio is very much related to the rational speed, the milling time and etc. Tests prove that the rotational speed ratios 1:2 (≤4L) and 1:1 ...

Each time the grate enters the mill charge, the horizontal force of the load in the mill deflects the grate. This stretches the rubber and forces any large material caught in the grate opening along through the grate slot. As the grate leaves the charge, the rubber assumes its original shape. This diaphragming action works the large particles ...

Work indices for the ag/sag mill and ball mill can be re-organised as 7 and 8, where bwio and awio are the corrected operating work indices and wag/sag, wbm are the respective power draw of ag/sag and ball mills.note that the ball mill operating work index is applied only on the portion that needs the additional grinding (q2), get more.

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills …

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 …

Ball Mill Explained - saVRee. If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
