Abstract

Good-quality oil paint production is crucial for creating impactful artworks in Ecuador. Achieving this quality requires a three-rolling mill machine. This project deals with the design, manufacture, and construction of the cooling system and the implementation of the control system. The cooling system consists of a 1/4 pulg. copper pipe arrangement that transports water to the three grinding rollers using a water pump connected to the pipe. This aquarium water pump can supply a flow rate of 2.5 lt/min. While the water circulates through the rollers, it absorbs the heat generated by friction during the paint grinding process. The heated water then collects in a reservoir fitted to the machine’s structure. Finally, the water transfers to a larger tank for treatment and recirculation. This allows the surface temperature of the rollers to be maintained in an optimum operating range. On the other hand, the control system consists of buttons that initiate and stop the machine. It also includes a speed reducer that provides a constant speed of 90 rpm to the mill’s drive shaft.
