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.

The rotational speed of the drum of an ore mill may be controlled variably over time. By rotating the drum during a first time interval at high speed, especially hard or dense particles are broken up by tumbling. At the same time, the discharge characteristics of the mill are adversely affected. In a subsequent second time interval, the drum is rotated at a slower speed, and the material is discharged more effectively, whereas the tumbling movement inside the mill is not achieved. The combination of said different modes of operation within short time periods in continuous operation may improve both the comminution as a result of a tumbling motion of the material and also the discharge of the ground material. By regulating the rotational speed with different target values within short time windows, different requirements for the movement behavior of the material to be ground and for the discharge characteristics of the ground material can be simultaneously optimized. This may allow a higher throughput for the mill.

Floor-standing equipment and methods that employ them use nylon netting to grate trim off the seedless flowers of female cannabis plants. The netting is formed into large cylindrical drum into which about five pounds of dried seedless flowers of female cannabis plants are loaded through a door flap in the netting. An electric motor or handcrank causes the load to tumble over and over a horizontal axle for 3-5 minutes at about 35-RPM. The trim drops through the netting down through a funnel bag into a plastic basin on the floor. The trimmed seedless flowers are then dropped out separately through the door flap in the netting and through the funnel bag into a second plastic basin on the floor.
