Case Study F : Pneumatic Conveying
- Paper Mill
This case study describes, in general
detail, the development of a pneumatic conveying system for paper
trim process re-cycling. Several trimming machines in a paper mill
were connected via an integrated ducting system to collect
continuous strips of paper trim from various trim rollers. These
continuous strips were ducted to a chopper fan which then fed the
material through the final ducting section to the re-pulping
unit.
Several
actuated diverter valves, forming
part of an integral control system for the factory, provided greater
control over the feed to the re-pulping unit. This system completely
eliminated time consuming and labour intensive manual transport
of the waste to the re-pulping unit. Further time and labour
saving was achieved at the re-pulping
unit, including an improvement in Occupational Health and
Safety (OSH) practices.
