This paper presents the design and fabrication of a sand sieving machine with multiple sieves that can be changed according to the usage of the work. As we see at every construction site, sand is sieved by old hand-operated (mesh sieving) techniques.

There appears very limited research on middle school students' experiences with simple machines, especially with respect to engineering-based units of study. One such research program (McKenna & Agogino, 2004) developed a learning environment to support middle and high school students' mechanical reasoning and understanding of simple machines.

This paper reports on the design, construction and Testing of a dry sand sieving machine. The sample to be sieved is uniformly graded. The coefficient of uniformity is 1.11, thus the machine design does not sieve larger particles such as gravel. The slip calculated is 36% which enabled the proper configuration of the V-belt. The theoretical …
