The diameter of feed roller of a conveyor type power chaff cutter is 100mm and they are rotating at 100 rpm for cutting the dry fodder. The effective length of each feed roller is 0.25 m and average clearance between them is 0.015 mm. The compression density while passing through feed roller is 350 kg/m³. What will be the capacity of chaff cutter?
The flywheel of a power operated chaff cutter receives the power through belt and pulley arrangement from an electric motor, running at 1600 rpm speed. The motor pulley has a diameter of 10 cm, while that of the pulley mounted on a flywheel shaft is 50 cm. The speed ratio between the flywheel and worm gear of diameter 15 cm is 7:1. What would be the rpm of flywheel and worm gear?
A power operated chaff cutter is used for cutting Napier grass of density 640 kg/m3 at 800 rpm speed. If blades make a clearance angle of 18° between the knife support assembly and the plan of rotation and distance of inner edge of throat from flywheel centre is 10 cm. What will be the theoretical length of cut without feed interference using 4 knives?
A field chaff cutter with cutter head has 4 knives and diameter of 650 mm. The given peripheral speed is 30 m/s and throat size is 45*15 cm. For 20 mm length of cut with corn silage what will be the linear speed and rated feeding capacity?
The flywheel of a hand operated chaff cutter with 4 cutting knives is rotated at 60 rpm and is connected to worm gear assembly for rotating feed rollers. The number of teeth and threads of worm gear and worm are 20 and 2 respectively. What would be the chaff length? (Diameter of feed roller is 15 cm)
