Abstract
Experiments were carried out through years of 2009 and 2010 at Super
Bio Company for Organic Fertilizers, Dakahlia Governorate to manufacture
and evaluate the performance of a small scale screening unit suitable for
compost cleaning.
The main objectives of the present research are to:
Manufacture of a local compost screening unit from low cost local
material suits conditions of Egyptian farms.
Carry out theoretical analysis to design the local compost screening
unit.
Optimize some different operating parameters (material feed rate, sieve
speed, sieve inclination angle and compost moisture content) affecting
the performance of the manufactured screening unit.
Evaluate the manufactured screening unit from the economic point of
VIew.
Evaluate the quality of the final product according to the international
standards.
The developed machine was manufactured specially for this work. The
developed machine consists mainly of screening device and feeding device.
The screening device separates the principle product (clean compost) from
coarse impurities and un composted material. The screening device consists
mainly of power source, transmission system, frame and cleaning unit.
The feeding device controls the compost feeding rate passing to the
cleaning unit. The feeding device consists mainly of power source,
transmission system, frame and rubber conveyor belt.
