Abstract: Brittle material (1) is ground batchwise as a bed of particles by compression between non-yielding hard surfaces at a pressure of at least 50 MPa. In order to reduce the energy requirement and machine expenditure needed for fine, superfine and microfine comminution, the bed of particles is subjected to repeated stressing by pistons (4) in different directions and at least in part successively. The stressing preferably is accomplished by groups of two opposed pistons (4), which are offset at an angle with respect to each other and which are rendered active one after the other. The stressing is repeated in another plane of the grinding chamber. Wet grinding is carried out in a closed grinding chamber from which the liquid expelled from the voids between the particles being ground can drain through at least one aperture of narrow cross section.
Abstract: The present invention discloses a device for recycling a tube such as a core having housing which has an upper side, a lower side, and a first side. Attached to the upper side is an input chute. The input chute receives the core. The bottom end of the core is fed into a traveling horizontal blade as well as a splitter blade. The travelling horizontal blade makes a horizontal cut proximate to the lower end of the core whereas the splitter blade makes a cut proximate to the lower or distal end of the core in a vertical direction. The same piston that pushes the splitter blade and traveling blade into the core then pushes the core into a stationary blade which makes another horizontal cut and separates a piece from the core which then drops into a storage area. The same piston which pushes the splitter blade and traveling blade can then push the pieces in the storage area toward a discharge chute.
