Abstract
A manually operated paper-recycling machine was designed and fabricated.
This was done to enable waste paper conversion into useful product. The
fabricated plant consists of six major component units that include the disc
refiner, the hydropulper, the head box, the felt conveyor, the driers and the
rollers. From the results of experimental analysis carried out on the study, it
was discovered that for every 0.1kg of used paper fed into the refiner, about
7000ml of water is required to defibre it, and about 0.2 kg of starch adhesive is
required. The calculated volume of the refiner, hydropulper and head box is
11795.62cm3
, 62930.47cm3
and 60979.096cm3
respectively. The fabricated
machine is capable of producing 7.6 kg of recycled paper from 10 kg of used
paper.
Introduction
Paper is one of the most important products ever invented by man. Widespread use of
a written language would not have been possible without some cheap and practical material to
write on. The invention of paper means that more people would be educated because more
books would be printed and distributed. Industry would grow because all the plans, blueprints,
Conclusions
The development of a manually operated used paper-recycling machine is much
cheaper than the automated recycling industries worldwide. The fabricated machine can serve
dual purposes, it can be manned permanently at a stationary position or it could be shifted
from one place to another as the case may be.
One great advantage to be derived from the use of this machine is that the cost of
running it is minimal compared to what it takes to run a full plant. The simplicity of operation
of this machine ensures that no too much technical skill is needed to operate it.
When the machine is well maintained, its durability is guaranteed.
