Abstract

This work reports the design of a laboratory polyurethane recycling machine. This machine was designed with the aid of Auto Cad and Inventor software in such way that it can be operated both manually and electrically-in case of power outage. The machine was made up of a mixing chamber which consists of the hopper and mixing drum, and the mixing chamber was sustained by the machine frame. The machine has a compression chamber which consists of the presser, screw and moulding box. The heating chamber of the machine consists of the pressure pot, pressure hoes to enable passage of steam from the pressure pot into the moulding box. Design calculations of the vessels were done with appropriate machine design formula. The assembled parts was also coupled are presented. The design are dimensioned in millimeters (mm), except otherwise stated.
