DetailsCurrent trends in grinding and sieving technology. Owing to their versatile functionality milling and sieving machines suit (almost) any processing scenario. Tobias Borgers, Head of Marketing, L.B. Bohle Maschinen + Verfahren . The pharmaceutical production of tablets is practically unthinkable without the use of a sieve or a mill.
DetailsThe 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 coating, or slurry containing 20–40% water by weight.
DetailsBall mill is an efficient machine for fine powder grinding and key equipment for grinding after the crushing. There are two ways of ball mill grinding: the dry way and the wet way. It is used to grind many kinds of mineral ores and other materials, or to select the mine.

DetailsBALL MILL Principle: The ball mill works on the impact between the rapidly moving ball and the powder material, both enclosed in a hollow cylinder. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Fig: Ball mill 13 14. Working: The drug is filled into cylinder 60% of the volume.
DetailsEven though there are several high-energy mills available for size reduction, only a few are used in the pharmaceutical industry for the wet or dry sizing process. Milling is an extremely inefficient unit operation with only 1–2% of the applied energy being utilized in the actual size reduction. Milling efficiency is dependent on the ...

DetailsBall 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 simulatneous change in the ball size.
DetailsAt low speeds, the ball roll over each other and attrition (rubbing action) will be the predominate mode of action. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Advantages: It can produce very fine powder. Ball mill is used for both wet and dry grinding processes.
