7.5 HP three-phase Sharma 16 inch commercial atta chakki, a vertical stone-type flour mill for commercial flour mills, grocery shops and grain or food processing units. It grinds approximately 60–70 kg per hour, depending on grain type, moisture and operating conditions, and handles wheat, rice, maize, bajra and other suitable dry grains. The mill uses third-pedestal grinding technology with a 16 X 4.5 Inch black emery stone, fed from a hopper of approximately 40 kg. A double-pulley, double-belt drive carries power from the 1440 RPM, 440 V motor, and a mechanically balanced build with standard-quality bearings helps reduce vibration and noise. A heavy-duty MS trolley on castor wheels makes moving and positioning easy. Its motor, emery stone and trolley suit flour mill operators and entrepreneurs starting a grain grinding business.
