DEVELOPMENT OF A 50-LITRE BATCH CAPACITY INDUSTRIAL MIXER

Abstract

This work focused on the development of a 50-litre batch capacity industrial mixer using locally sourced material. The essence is to produce an industrial liquid mixer that is relatively cheap and easily affordable. The design is simplified in such a way that limits operational hazards. The development of the machine involved the use of simple fabrication techniques and methods for each component part so as to eliminate unnecessary complexity, for ease of maintenance. The electric motor capacity is 0.5hp. Calculation results gave the volume of vessel as 70. 372 liters, the total tension on the belt as 1033.063N, the force acting on the impeller as 197.867N, the power required to drive the 2 impellers as 22.694Watts (0.0304hp), the belt length as 254.435mm, the minimum length of the shaft as 760mm, the equivalent bending moment acting on the shaft as 142.603Nm, the equivalent twisting moment acting on the shaft as 71.371Nm, the shaft diameter as 20.5mm. Performance testing shows that the machine performed well as expected. The highly homogeneous product obtained during testing proves the viability of the machine and is indicative of the overall efficiency of the machine.
