The advantages of efficient waste handling systems cannot be ignored: labour costs for clearing and preparing trim can be kept to a minimum. Automatic collections at source frees valuable production space, minimises potential safety and fire hazards and allows machines to operate to their maximum capacity.
The waste is a nuisance in the production area becoming costly, time-consuming, and a danger. Delta NEU develops the Chopper Fan system. It provides the suction for automatic collection at source. The waste is then drawn through the Chopper Fan and reduced to small pieces before it is conveyed to the separator.
Fully automated sequenced systems result in substantial energy savings, operating only when required and recycling warm, filtered conveying air back into a building for space heating. A complete solution.
In the production of the corrugated board, where the edges are cut, a trim extraction system uses a Chopper fan® to provide the airflow and continuous trim, chopping to move the waste material from the pick-up hoods to the centralised collection in the baler room where the loose material is compressed into bales for cost effective transportation to the recycling process. The ducting network is carefully designed to balance the airflow between the numerous collection points maintaining air speeds in a tightly controlled range to ensure effective scrap extraction at every point.
In the baler room, the waste is separated from the conveying air in an AMSP separator through a stainless-steel mesh screen. The waste material then discharges for the base into the baler feed arrangement and the air is discharged for the clean side of the screen using a balance fan or rotary valve and discharged. Either a balance fan or rotary valve ensures the material feeding into the balers does so without pressure which would blow waste and dust into the surrounding area. The use of rotary valve or balance typically depends on the number of trim systems connected to the separator and whether the air requires subsequent dust filtration
