Fabrication of Concrete Mixer machine

Abstract

This paper describes fabricate a concrete mixer machine, which is a device that homogeneously combine cement, aggregates, and water to form concrete. This machine was designed and manufactured in the Institute of Engineering Technology, Baniwalid, Libya. It uses an electric motor with a rotational speed of 320 rpm and a voltage of 220 volts to rotate the cylinder. Maximum mixing force at 16 kg maximum mass (concrete components with cylinder mass) is 160N. Sprockets and chains were used to transfer the speed from the engine to the mixing cylinder in two stages, to reduce the rotation speed from 320 rpm to 53.6 rpm. The manufactured design showed that the concrete mixture produced is homogeneous, which indicates the efficiency of the manufactured machine in terms of mechanical performance. This project aims to localize design and manufacturing processes using reverse engineering and simulating of existing products and making them practical and sustainable in order to reduce dependence on imports and provide job opportunities for the local market.
