Abstract

The present invention concerns a machine for breaking up bulk material by means of a cutting mechanism which comprises at least two shafts driven contradirectionally and equipped with cutting tools, and is supplied with the material which is to be broken up via a chute or hopper leading to the working area of the cutting tools, the drive to the cutting mechanism being switchable into reverse drive in case of overload, as a function of a preset nominal drive value, and back again into forward drive, characterised in that the feed chute or the like may be closed off by a shutter element. The operation of the machine is controlled by a control circuit which takes into account, in controlling the cutter drive and the shutter, the motor temperature and r.p.m.
