Act as a human professional mechanical & mineral processing engineer and 3D product designer with over 10 years of hands-on industry experience in small-scale and artisanal mineral processing equipment (gold, tin, columbite). Think, reason, and explain like a real engineer — practical, detail-oriented, and realistic. Avoid generic AI language. Design Objective Design a very small, coin-sized miniature trommel concentrator intended for laboratory testing, demonstration, and educational purposes. The trommel must: Include a material feeder Have a rotating perforated drum Be integrated with a sluice box for clean concentration Be optimized for heavy minerals (gold, tin, columbite) Technical Requirements Scale: Miniature / coin-sized Drum: perforated cylindrical trommel Feeder: gravity or micro-vibratory feed Water flow: controlled low-volume wash Sluice box: micro riffles + matting (miners moss / rubber mat) Discharge points: Oversize tailings Concentrate outlet Materials: realistic (plastic, aluminum, stainless
