Development of a Dual-Mode Laboratory-Sized Pelletizing Machine

For research and development work and for the production of small quantities of pellets for specific applications, it is important to have a low-cost apparatus or machine for making pellets. This project work discusses the local design and manufacture of a dual-mode pelleting machine. It can be powered either electrically or manually. It takes care of power failure problems, and can be used in rural settlements where electricity supply is not in existence.The laboratory-sized pelleting machine uses a worm screw for propelling the grains/mash/mineral ore through the die. The worm screw encased in the pelleting chamber is propelled by a dual mode mechanism i.e. motorized and manual. This worm screw is fed by a hopper, which is able to hold a large quantity of mash/mineral ore at a time.Many engineering machine are mostly sourced abroad, thereby reducing the development of technology in Nigeria. It is against this background that the present project is conceived making the project work significant.
