Abstract: A machine for the continuous comminution and mixing of materials, especially animal and vegetable media, has a mixing chamber in which two conveying passages are arranged. Each passage has a conveyor and mixer element working oppositely to one another, with each conveying passage there is associated a comminuting device which at the same time acts as a conveying means to deliver materials in the same direction as the associated conveying and mixing elements into the relevant conveying passage or respectively draw therefrom. Reversing spaces or passages serve together with these passages for the circulation of the mixed material.

Abstract: A geared transmission having a continuously rotating input shaft and having output members, one of which is intermittently driven at variable speeds and the other of which is intermittently driven during idle periods of the first driven member. The unit includes an arrangement for bypassing the intermittent drive of the first driven member so that it can be driven continuously by the input shaft.
