Abstract

A process for industrial disposal for electro-waste. The process contains steps for separating material that are contained in such waste, for re-introducing material into a re-using process in order to save resources and to meet ecologic and economic interests.

Abstract

This invention relates to a machine for noduling of metal scrap that can upon conversion be used for comminuting such scrap. Machines capable for taking over the function of one of those machine types for that of the other of these two machine types solely by conversion are not yet known in this field. Frequently machines for comminuting are constructed by a bipartite frame solely for cleaning purpose. One part is solidly fixed to a foundation while the other one is fixed to the first one by hinges and a locking device, so that it can be turned away from the first part of the frame. One object of this invention is to further develop such machines that an exchange of worn components is possible and that simply by conversion and by saving of time, one sort of usage can easily be transfer-red to the other one. For this purpose this invention recommends to mount the complete rotor-block together with its bearings on a swivelling arm that can be turned away from the frame of the machine in order to enable free access to the interior of the machine.

Abstract

A process and device for separation of plastic material from other stuff of a various density by a flotation process in a liquid bath. The process involves discharging heavier stuff that settles on the screen bottom by a movable screen bottom slowly moves in the direction of reducing a slot that exists between one edge of screen bottom and the wall of the flotation tank and then after having reached a final position too quickly and abruptly move in the counter- direction. That movement occurs in intervals. This abrupt motion of screen bottom initiates that kinetic energy accumulated in the heaps of metal and other heavy stuff moves this stuff towards the slot-edge and through the slot into a collection- container underneath the screen bottom to be discharged.
