Design and Fabrication of Portable Motor Driven Concrete Mixing Machine: A Review

Abstract

Abstract: The aim of our paper is design and fabrication of portable concrete mixture machine. Mixer widely used to make a concrete mixture which used to building construction and other industrial application such as concrete block, pipe, sheets, etc. As for all materials, the performance of concrete is determined by its microstructure. To determine the mixing method best suited for a specific application, factors to be considered include: location of the construction site. the concrete mixture machines which are currently available in the market is heavy and having big capacity of concrete mixing. Continuously and easy handling, we have fabricated this concrete mixture machine. The construction and building industries are expanding on a daily basis as a result of increase in human population and continually demand for shelter. Concrete which comprises mainly of sand, cement and gravel is an important component required for construction of houses and roads. However, most operation of mixing concrete in Nigeria is done manually as a result of lack of insufficient machinery and high importation cost. In this research, I carried out the design of a low-cost concrete mixing machine. The materials used in this research work are as follow; sand, gravel, water, mild steel, hopper, electric motor, shaft, bearing, V-belt, angle bar, mild steel plate, bolts and nuts, etc. In other to achieve a good design, feasibility studies, and preliminary tests were carried out. The materials selected for this design were justified. Keywords: portable mixer, design model, mixing volume, power, torque, belt tension
