Abstract

Experiments were carried out to evaluate the performance of a trommel screen for compost cleaning to increase product quality. Theoretical analysis was conducted for optimizing sieve speed and sieve inclination angle. The machine performance was studied as a function of change in material feed rate, screen opening size and compost moisture content. Performance evaluation of the trommel screen was carried out in terms of machine productivity, separating efficiency, compost losses, cleaning efficiency, required power, energy requirements and criterion cost. The experimental results reveal that the performance of the trommel screen during compost cleaning was in the optimum region under the following conditions: -        Operate the trommel screen at a sieve speed of 30 rpm (2.5 m/s). -        The slope angle of the cylindrical sieve on the horizontal plane             (sieve inclination angle) should be lower than 27 degrees. -        The screen opening size should be of about 13 mm. -        Clean compost at a moisture content of about 40 %. -        Operate the trommel screen at an average feed rate of 10 Mg/h.
