Design and Fabrication of Compact Coconut Shell Crusher

Abstract

The scope of this project was to design and development of coconut shell crusher machine focus on chopping of coconut husks and shells. The crushers are mounted on two shafts, which rotate parallely driven by a spur gear. The power from the electrical motor is transmitted to cutter shaft through a belt drive. Crushing is made inside the crushing house due to the effect of tensile, friction, and impact effect in crushing process. The coco powder gets crushed and powder is collected at the bottom. Compact shell crusher machine is a fibre extracting machine from the husk and shell of coconut and used as an excellent soil conditioner and is being extensively used as a soil-less medium for agri-horticultural purposes. With its moisture retention qualities, coir pith is ideal for growing anthuriums and orchids. Available in raw form or converted into organic manure. Although a water Irrigation Sprinkler system could meet the needs with presence and monitoring during the growing season, continual presence of the worker to control irrigation automatic instruments is not economic. Through advancements in technology and advent of processors and controllers, it will be more serious improving the role of farmer as an observer off-field particularly in the light of new irrigation systems.
