A dispersion of suspended single-layer graphene, multilayer graphene, and graphite is used. A magnetic field is applied to the dispersion to separate the single-layer graphene from the dispersion. By applying the magnetic field, the single-layer graphene, the multilayer graphene, and the graphite are situated at different locations in solvent by the difference in the diamagnetism strengths of the single-layer graphene, the multilayer graphene, and the graphite.

A method for retrieving active material from a galvanic cell is provided. The galvanic cell includes an active material, a support for the active material and a binder for bonding the active material and the support. The method includes the following steps: (a) crushing the cells, in particular under inert gas or in a vacuum, so that solid cell fragments are also formed, (b) heating the solid cell fragments up to the decomposition temperature (T.sub.z), which is high enough to make the binder decompose so that it loses its binding properties, preferably under inert gas or in a vacuum, such that heat treated cell fragmented are formed, and (c) classifying the heat treated cell fragments, whereby (d) the classifying comprises air jet sieving and (e) the air jet sieving is carried out in such a way that the active material is separated from the support.

The present invention relates generally to wood chippers and baling machines and methods of operation therefor, and more specifically, to an apparatus and a method for chipping tree branches and the like and baling wood chips formed from such chipping activities. The apparatus includes a chipper assembly having a chipping mechanism operable to reduce the trimmed branches to wood chips. Also provided is a bale forming assembly operatively connected to the chipper assembly. The bale forming assembly has a housing and a baling mechanism contained within an interior space of the housing. The housing has an opening defined therein for receiving wood chips from the chipper assembly. The opening provides access to the interior space of the housing. The baling mechanism is operable to form a bale from the wood chips produced by the chipper assembly.

The present application pertains to a process for the decomposition of biomass-material.

The invention relates to a method and to an assembly for recycling plastic materials, comprising the following processing steps: a) reprocessing the raw material, wherein the material, if necessary, is comminuted and brought into a fluid-like form and heated and permanently mixed, while preserving the lumpiness and pourability thereof, and optionally the viscosity thereof is increased and/or it is degassed, softened, dried and/or crystallized; b) melting the reprocessed material, at least so much that filtration is possible; c) filtering the melt in order to remove impurities; d) homogenizing the filtered melt; e) degassing the homogenized melt; and f) discharging and/or subsequently processing the melt, such as by granulation, blown film processing, with said processing steps being carried out consecutively in the order listed.

A method for milling flex foil includes providing a web (14) of flex foil including a substrate; a first conductive layer arranged on one surface of the substrate; a second conductive layer arranged on an opposite surface of the substrate; a first insulating layer arranged adjacent to the first conductive layer; and a second insulating layer arranged adjacent to the second conductive layer. The method includes dry milling one side of the web using a milling wheel (20-1) and a first cliche pattern (25-1) (including a rotating drum (24-1) and a flexible substrate (26-1)) including raised portions and non-raised portions to selectively remove at least one of the first conductive layer and the first insulating layer. The method includes dry milling an opposite side of the web using a milling wheel (20-2) and a second cliche pattern (25-2) including upper raised portions, lower raised portions and non-raised portions to selectively remove the second insulating layer.

A nut lifting tool of an inner wear part of a cone crusher. The lifting tool has a frame to be placed around a nut to be lifted. The frame has nut lifting lugs for supporting occurring from at least three sides of the center of gravity of the nut and frame suspension brackets for suspending the frame from the nut before lifting the nut. The frame also has an open side for receiving a nut, lateral limiters, which, together with the lifting lugs and the suspension brackets, form a nut receiving space such that the frame can be slid from the open side to surround the nut, and lifting connection pieces for connecting a crane to the frame.
