Italmaceri SpARozzano | Milano - Italy
- System description: Sorting
- Waste processed: Waste paper, offi ce paper and magazines packs
- Plant capacity: Two lines, 5 t/hour each
The sorting plant built by Ecomaster for Italmaceri SpA is primarily used to treat the following materials:
• Packs of unsold magazines returning from stores;
• Paper and cardboard from source-separated municipal waste;
• Paper from offices;
• Cardboard packaging material from commercial activities.
Magazines, especially women’s magazines, often contain some gadgets, such as jewels, perfume bottles and small watches, which must be separated to use such
magazines as recycled paper. One of the lines in the plant is mostly used to open the packs of magazines and separate gadgets and wrappings from paper.
The plant includes two lines, each one of which is equipped with a horizontal feeder, a lifting conveyor and a sorting conveyor.
The horizontal feeder conveyors and the sorting conveyors are equipped with variable frequency drives, to adapt the flow of input material to the type of material treated and to the operations that must be performed in the sorting room. Both sorting conveyors are set up in a large room, equipped with ventilation and heating systems. Operators remove the packs of magazines, cut the strings and separate wrappings and gadgets. The magazines are then dropped in the channels that bring them below into storage bunkers, while unwanted materials proceed on the sorting conveyor that collects them in a third bunker.
The second line of the material recovery facility is normally used to sort paper and cardboard deriving from the collection of source-separated municipal waste, or consisting of waste paper products from offices. It is possible to separate the waste into three fractions with a higher market value than mixed material, e.g.
white paper, newsprint and cardboard. Under the sorting room, in a longitudinal position, there is a conveyor receiving the various materials from the storage
bunkers. By means of a wheel loader, the materials are pushed onto this conveyor which takes them in turn to the adjacent building for baling. The baler and the
other equipment operating in this building has been acquired directly by the client from third parties.
To prevent the various materials stored in the bunkers from falling into the conveyor pit, every bunker is equipped with an electrically driven door, which is opened
only when that specific bunker needs to be emptied.
