Abstract

The paper industry is growing continuously due to the increase in demand from the private sector. For this reason, the shredder machine has become an important piece of equipment used to dispose waste paper at a low cost. Two types of shredders have been employed: single and double rotor machines. However, it was established that the double shaft machine is not as effective as the single rotor machine. This study aims to investigate the performance of a single-rotor paper shredder machine. In the testing process, the related literature and research were reviewed to identify the characteristics of a paper shredder machine. The experiments were performed by using a 10 HP engine to investigate the performance of paper shredding at various rotating speeds including 300, 450, 600, 750, and 900 rpm, respectively. Results showed that 750 rpm was the most efficient rotational speed of the single-rotor paper shredder machine with 45 degrees of feeder angle. Furthermore, the total amount of shredded paper was 340 sheets per minute, which is higher than the amount of shredded paper for other multi-rotor machines. The total fuel consumption was 14.7 mL per kilogram of paper. The shredding force was 4.3 N per sheet, which is lower than those of other multi-rotor machines. ANOVA analysis revealed that the two parameters (feed angle and the rotating speed) have significant effects on the shredding rate of the machine.
