Effect of Size of Multiwalled Carbon Nanotubes Dispersed ...

The aim of the paper is to investigate the effect of size of multiwalled carbon nanotubes (MWCNTs) as additives for dispersion in gear oil to improve the tribological properties. Since long pristine MWCNTs tend to form clusters compromising dispersion stability, they are mildly processed in a ball mill to shorten the length and stabilized with a surfactant before dispersing in lubricant.

The effect of ball size on mill performance - ScienceDirect

The specific rates of breakage of particles in a tumbling ball mill are described by the equation S i = ax α i (Q(z), where Q(z) is the probability function which ranges from 1 to 0 as particle size increases.This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by x m = k 1 d 2.The variation of a with ball diameter was found to be of the form ...

Mill (grinding) - Wikipedia

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

A study on the effect of ball diameter on breakage ...

volume of mill, the rate of ball-on-ball contacts per unit time increases with the increase in ball diameter, because the number of balls in the mill increases as 1/d3. Thus, the rates of breakage of smaller sizes are higher for smaller ball diameters. The relation with T a and ball diameter in a 0.6 m diameter mill were given as aT α 1/d 9.
