Design of an organic waste biogas crushing blower with a capacity of 200 liters

Abstract

The development of machine technology has made things easier and faster for people, encouraging the public and the business community to use waste, especially organic waste, as a feedstock for biogas. When using waste as feedstock for biogas, a waste grinder is needed to speed up the decomposition process in the digester. When designing a biogas organic waste crusher, several planning methods should be adopted, namely: data research, data processing, design and production, machine planning, calculation of the machine, the manufacture of the machine, the production of trials and the writing of reports. So the required motor power is 0.342 kW, and is chosen according to what is on the market with a power of 0.373 kW or the equivalent of 0.5 HP. Determined in each chopper the machine is capable of chopping (m) 10 Kg (each chopping), and the number of blades in the shaft (z) 12 Blades, and (n2) Motor Rotation. The crushing drum is 420mm, the total height is 750mm, using a shaft with a diameter of 25 mm and a shaft length of 810 mm, it can cut up to 56 kg of mango skin per hour requires a motor power of 0.5 horsepower (0.373 kilowatts) at a speed of 2800 rpm.
