Development of a Paint Mixing Machine

Abstract: Paint production is an important process which has wide applications in several fields. The report entails the development of a paint production machine. The machine essentially comprises of a 3 kW variable speed electric motor, a ball valve, a pillow bearing, 3 mm thick stainless steel cylindrical tank and a stirrer assembly that rotates in the tank with four baffles to control the splashing. Performance evaluation of the developed paint production machine was carried out with the production of emulsion paint at different stir speed ranging from 100-500 rpm. From the result obtained, increase in stir speed beyond 300 rpm leads to decrease in paint viscosity as well as production time. In conclusion the machine has a fast production time than conventional machine while also being environmentally friendly and cost effective
