Laboratory ball mill

Abstract

Shown and described is a laboratory ball mill, in particular a vibrating mill, centrifugal ball mill or planetary ball mill, further in particular a planetary ball mill with a transmission ratio of 1:−1, with at least one grinding bowl holder for at least one grinding bowl arranged on a machine part of the ball mill which is moved during the grinding operation of the ball mill, with a clamping device arranged on the moving machine part for transmitting a clamping force to the grinding bowl and with a coupling device with at least one coupling element, wherein an energy transmission from the stationary machine part to the moving machine part for generating the clamping force is provided via the coupling device. According to the invention, it is provided that the coupling element is coupled to the stationary machine part and to the moving machine part during the grinding operation.
