    The invention relates to a planetary mill having two stationary backing bodies, arranged one above the other in chocks in a roll stand. Two synchronously rotary-driven cage rings that are separated from one another and rotate in parallel planes of rotation are coaxially mounted on the backing bodies. Each of the two cage rings holds, one end of work rolls and/or intermediate rolls that are arranged between them

  • Planetary Ball Mill 911Metallurgist

    Planetary ball mill is a very often used machine for mechanical alloying, especially in Europe. Because very small amount of powder (for example, as little as a few grammes), is required, the machine is suitable for research purposes in the laboratory. A typical planetary ball mill consists of one turn disc (sometimes called turn table) and two or four bowls. The turn disc rotates in one

  • Ball mill Wikipedia

    A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel. The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio: 1:−2 or 1:−1). The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so-called Coriolis forces. The difference in speeds between the balls

    There are commercially available batch-type planetary mills where the volume of a material loaded in one jar ranges from 75 ml up to 2.4 l. Usually there are 4 drums in one mill. Milling is fast enough and throughput rate can attain 36 kg/h. High-performance mills use accelerations up to 20 G. In the autogeneous grinding mode, the coarseness of initial material can be up to 60 mm for the largest

  • PLANETARY MILL FOR PRODUCING SCALLOP-FREE

    In a planetary mill, a heavy backing roll is surrounded by a plurality of work rolls which orbit around the backing roll. The orbit of the work rolls is of course circular. The result of this situation is that the strip produced is made up of short sections, each of which has been rolled by one pair of the procession of work rolls. These short sections, because of the circular orbit of the work rolls, show up noticeably as
