Design and Analysis of Shredder Machine for Waste Management

Fertilizers are necessity of farmers. With the use of synthetic fertilizers land fields get damaged and also it is costlier. Organic compost is a better option for synthetic fertilizers. Designed shredder machine for chopping agricultural waste and convert it into powder. This chopped powder is used to prepare the compost. A Concept was developed with reference of four different shredder machine and operating processes. Concept was developed considering the safety factor users operating environment and maintenance. The machine consists of three-phase 1.5 HP motor, spur gear, bearings, structural frame, cutter and two shafts. Twenty eight cutters are mounted on two shafts, which rotate parallel driven by a spur gear. The power from the electrical motor is transmitted to cutter shaft through a chain drive. Cut is made inside the chopping house due to the effect of tensile, friction, and impact effect in chopping process. The garbage gets chopped and powder is collected at the bottom.
