FABRICATION OF A PEPPER GRINDING MACHINE

Abstract

The process of crushing and grinding domestic product into powdered form was approached and achieved in this project work taking into account some necessary modifications due to the limitation found in the previous design machine. With the continuous improvement and advancement in the present days technology has brought the invention and making of diverse types and shapes of machine. These machines require different kind of energy for its operation and to produce useful work and it does not waste time. Most of them are operated manually or electrically. Basically, the pepper grinding machine is a useful device for achieving grinding of agricultural product like pepper food stuff and all type of grinding operations. In this grinding mill, the urge shaft is adequately supported with bearing to reduce the supporting materials. The posterior is also fabricated in such a way that there is room for adequate lubrication. These adequate supports given to the urge shaft help to reduce the frictional forces and there by ensures long lifespan of the machine. The materials used for the fabrication of this project are readily available and can withstand the mechanically applied force or stresses
