Design Specifications

Agsol's Solar-Powered Mills are solar-powered agricultural machines, available in two variants: the Hammer Mill for milling flours, and the Rice Mill for milling grains, which differ in milling head size, screens, and exit gates. The dimensions are 670 x 360 x 700 mm for the Hammer Mill, and 480 x 290 x 925 mm for the Rice Mill. Both weigh around 40-45 kg. The product is offered with brushless DC and AC motor options and has a motor rating of 1.3-1.8 kW and for a 48V DC system, and 2.2 kW for an AC 1-phase or 3-phase system. The Hammer Mill has an efficiency of 39-50 kg/kWh and a production rate of 50-85 kg/hr based on maize milling with a 1 mm screen; production for cassava is doubled and millet is tripled. The Rice Mill has an efficiency of 90-115 kg/kWh and a production rate of 135-160 kg/hr.
