Development of Automatic Sand Sieving Machine

This paper focuses on the design and fabrication of an automatic sand sieving machine aimed at improving the efficiency, speed, and accuracy of conventional sand separation methods. The concept originated from a project task assigned by the supervisor, highlighting the need for a mechanical solution to overcome the limitations of manual sand sieving, which is labor-intensive, time-consuming, and often results in inconsistent particle sizes. The proposed machine is designed to minimize manual effort while maximizing productivity. It incorporates a motorized system to drive the sieving mechanism, ensuring uniform separation of sand particles into different grades. The development process includes conceptual design, mechanical analysis, material selection, fabrication of components, and assembly of the complete machine. A comparative review of existing sand sieving devices informed the design improvements, enabling enhanced performance and reliability. The resulting machine is compact, portable, and user-friendly, with interchangeable screens to produce sand of various sizes suitable for construction purposes. It is expected to provide a cost-effective, robust, and efficient solution for small- to medium-scale constructionprojects, reducing labor costs and operational time while maintaining consistent quality of sieved sand.
