PROCESS FOR MANUFACTURING FULLY RECYCLABLE MINING SCREENS
20220023916 · 2022-01-27 ·

The present invention provides an environmentally-friendly, fully recyclable composite mining screen which has sufficient rigidity to replace existing metal and metal covered plastic mining screens. The inventive composite screen insert contains stiff reinforcing fibers (glass, carbon, etc.) and exhibits the rigidity of metal and metal-covered plastic mining screen inserts so as to minimize deflection in use. The inventive mining screen is also completely recyclable because at the end of its useful life, the broken and used screen can be ground into polymer particles and the particles incorporated into new screens or other parts.

METHOD FOR RECYCLING CONTAINERS
20210354333 · 2021-11-18 · ·

A method for recycling containers, including the following steps (1) to (4): a collecting step (1) of collecting containers, each of which is made of a sheet material including a plurality of layered film layers including a first resin film layer and a second resin film layer, is formed into a bag by attaching at least a part of a periphery of the sheet material to form a containing region for accommodating a content inside the second resin film layer, and includes, between the first resin film layer and the second resin film layer, a film attached portion and a filler enclosed portion; a shredding and washing step (2) of shredding the containers to obtain shreds, and washing the shreds; a recycled resin forming step (3) of forming a recycled resin by using the shreds; and a sheet material forming step (4) of forming at least a part of the sheet material by using the recycled resin.

PROCESSING PLANT AND METHOD FOR PROCESSING PLASTICS MATERIAL FOR THE RECYCLING THEREOF

The invention relates to a method and a processing plant (1) for plastic material, for the recycling thereof. To this end, the processing plant (1) comprises a feed device (4), a processing unit (2) having a comminuting device (5) and a conveying device (6) adjoining the comminuting device (5), and an extrusion device (3) having an extruder screw (21). During its conveying movement along a first conveying section (9) toward a transfer region (8) by means of the conveying device (6), the comminuted plastic material is heated to a transfer temperature with a mean temperature value, which falls into the range of the softening temperature of the plastic material. In the transfer region (8), the comminuted plastic material is transferred to the extrusion device (3).
