When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of wedge shaped slots tapering toward the discharge.
Around 110 years ago a Danish engineer, M. Davidsen, patented a pioneering invention in France which involved a tube mill with a charge of steel balls or flint pebbles for fine grinding of sand or cement. F.L. acquired the rights to his patent and started selling an improved version of this mill all over the world. For the.
Ball mill - Wikipedia
A ball mill is a type of grinder used to grind and 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.

Rod mills, how they function
Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about.

Vibration ball mills: Have they a place in pigment and resin .
Abstract: The vibrational ball mill has been around for close on fifty years and yet, it seems to have made only minor impacts in the pigments and resin industries. Looking at the techniques of vibrational milling one notes that such a method of comminution, or grinding, is very much faster than, say, a conventional ball mill.
