It consists of a drive shaft with varying chipping clearances (6, 18, and 28 mm) to produce varied chip geometry. The average throughput capacity of the chipper was found to be 475.5 kg.h^-1 at a speed range of 460-800 rpm with a chipping clearance of 6-28 mm. The average chipping efficiency ranges from a minimum-maximum of 76.6-99.4% for the selected operational speeds and chipping clearances. The chipping capacity and the output to input ratio is dependent on the operational speeds and chipping clearances of the machine. cassava roots; efficiency; moisture content; operational speed; throughput capacity 10.17221/102/2020-RAE https://rae.agriculturejournals.cz/artkey/rae-202104-0003.php https://rae.agriculturejournals.cz/artkey/rae-202104-0003.php continuing 67 4 171 180 2021 12129151 periodical academic journal
