Patent ID: 7469846

Claim:
A method for the wet mechanical processing of a mixture of materials using water as solvent, detergent and separating agent, the method comprising the steps of: continuously mixing the mixture of materials in a mixer with water as separating agent and detergent, without separating off compounds of the mixture, until a dry substance content of 15% to 25% is obtained, a) thereafter discharging the mixture of materials from the mixer by means of a conveyor, adding water to the mixture such that light components remain dissolved in a solid/liquid mixture having a dry substance content of 10% to 20% and heavy components settle and are separated by means of the conveyor as a first inert heavy fraction having a grain size of >25 mm, sieving off, rinsing, and pressing from the remaining solid/liquid mixture, organic light materials having a grain size of 30 to 120 mm as a first organic light fraction, b) thereafter separating by sieving and rinsing from the remaining suspension having an adjusted dry substance content of 6% to 12% first inert heavy materials having a grain size of 2-25 mm by gravity and subsequently further organic light materials having a grain size of 3 to 30 mm, c) thereafter separating from the remaining suspension having an adjusted dry substance content of 3% to 8% further inert heavy materials having a grain size of <2 mm by centrifugal forces and subsequently separating by sieving and rinsing further organic light materials having a grain size of 150 μm to 3 mm.
