If a ball mill contained only coarse particles, then 100% of the mill grinding volume and power draw would be applied to the grinding of coarse particles. In reality, the mill always contains fines: these fines are present in the ball mill feed and are produced as the particles pass through the mill.

To calculate hydraulic retention time (HRT), use the formula: HRT = Volume / Q, where: HRT Hydraulic retention time [h]; Volume Volume of the tank or reactor [m³]; and. Q Influent volumetric flow rate [m³/h]. Let's say, for example, that you'd like to find the HRT of an aeration tank with a capacity of 3000 m3, and the plant's ...
The formula for critical speed is CS = 1/2π √ (g/ (Rr) where g is the gravitational constant, R is the inside diameter of the mill and r is the diameter of one piece of media. This reduced to CS = /√ (Rr). Dry mills typically operate in the range of 50%70% of CS and most often between 60%65% of CS.

CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

calculate ball mill retention time 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 b. Calculate the retention time of cement in a cement mill.
(9) and Eq. (10) can be used with confidence. The data show that the ball mill grindability tests at 28 mesh are somewhat less accurate than the others; this is expected because of the low ratio of reduction and the short retention time in the mill, when grinding prepared minus 6 mesh feed.
If an ore is ground in the vibratory ball mill under conditions where the retention time varies, a loglog plot of the size modulus, k, vs the retention time at constant power, (tr)P, should yield a straight line of slope 1n.
