Sharma 20 HP double-stage cyclone pulverizer, a double chamber commercial atta chakki for flour mills, wheat grinding and grain processing, sold as "With Out Motor". Its two-stage mechanism runs six beaters in the first stage and four in the second (6 + 4 Cutter) inside a cast iron (CI) grinding chamber described as 16-inch, with chamber sizes listed as 16 X 5 & 9 X 4 Inch. Approximate capacity is given as 110–120 kg per hour, and also as 100 to 130 Kg; output varies with grain type, moisture content, screen size and operating conditions. A heavy-duty fabricated body suits frequent commercial running. Anti-vibration pads reduce vibration, and the machine installs directly on a firm, level, load-bearing surface. An oil tank lubricates the bearings, and a single motor drives both the grinder and the blower, with the motor listed as 20 HP Three Phase at 420 V. Speed is given as about 3,000–4,000 RPM, and also as 1440 RPM. High-speed running is louder than a traditional stone-type atta chakki, so hearing protection suits a noisy work area. The brown powder-coated unit has a top feed hopper, a hinged front door opening onto a beater rotor and perforated screen, a side blower, and tall ducting to a cyclone with white cloth bags at its top and outlet, all on a bolted angle stand. Material is listed as "CI Castin (Iron)" and approximate weight as 350 Kg. It suits commercial flour mills, atta chakki businesses, grain-processing units, small and medium food-processing businesses and entrepreneurs planning a commercial grinding operation. Also known as a double chamber cyclone atta chakki, cyclone pulverizer, double stage atta chakki and high-capacity flour grinding machine.
