Ball mass is an important parameter that is known to have an influence on the outcome of a mechanochemical reaction induced by ball-milling. A standard way of modifying the ball mass is to change the size of the ball made of the same material. In this case, however, a change in mass is accompanied by a simul Editor’s Collection: Mechanochemistry The Solid State of Pharmaceuticals

like ball size, ball and vial material, ball to powder ratio, milling time, milling environment and temperature rise are involved in the milling process which may affect the characteristics of milling [12]. To produce an amorphous powder effectively it is very much important to control these milling variables.

We investigated tlte effects of ball diameter and feed size on the rate constant when the ball mass, feed mass, and the mill''s rotational speed were constant. The results indicated that the grinding rate constant can be expressed by modifying the equation that was proposed by Snow as the function of ball diameter and feed size. 1.

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23%

A ball mill is a type of grinder used to grind or blend 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 rotating about its axis. T

Gupta 27 showed that the particle size influences the breakage rate in a laboratory mill. In the present work, effects of ball size and specimen size on the breakage throughput are investigated by using a common drop-weight test machine. Regular square-shaped building stones, which have been cut in precise sizes, were used for this aim.

When speed and ball filling rate is determined, grinding effect depends on position of the ball in ball mill and type, size and proportion (graded) of ball. In the running ball mill, grinding ball is distributed according to certain rules. From the feed end to the discharge end, ball diameter is gradually reduced.

The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results. In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time.
