Innovative Movable Electric Sand and Gravel Processing Machine with Dual-grain size Separator

Abstract Movable electric sand and gravel processing refers to a mobile, electrically powered system that screens, separates, and conveys aggregates on-site, thereby eliminating the need for fixed installations and reducing manual handling. This study designs and evaluates a mobile electric sand-and-gravel processing machine with a dual-grain-size separator to improve throughput, safety, and classification accuracy. The design integrates mechanical drive systems, granular-flow behavior, and sieve analysis, complemented by monitoring and control to ensure reliable operation. Using a descriptive-developmental approach, we assessed technical requirements, core functionalities, and user acceptability through surveys, pilot testing, and analysis. Evaluation focused on stability, separation precision, durability, efficiency, maintenance simplicity, and ergonomics. Results indicate potential reductions in labor and material waste and in exposure to hazards, while supporting sustainable construction practices and aligning with infrastructure goals. Performance is optimal with a relatively uniform, low-moisture feed; efficiency decreases with highly variable particle shapes or high moisture content. Applicability is limited to relatively uniform, low-moisture sand and gravel, with performance diminished for highly irregular mixtures or high humidity. Outputs will inform a concise user manual and benchmark efficiency gains relative to manual screening. The study at CTU-Tuburan involved 10 experts and 40 non-experts to support rigorous, context-aware evaluation and stakeholder relevance.
Keywords dual grain size separator, movable electric sand and gravel processing, on-site aggregate screening, sieve analysis, sustainable construction
