DOMESTIC ELECTROMECHANICAL GRAIN GRINDER AND DOMESTIC ELECTROMECHANICAL PROGRAM-CONTROLLED GRAIN GRINDER Russian patent published in 1996 - IPC

FIELD: grain grinding equipment. SUBSTANCE: grinder has casing with receiving-feeding device, three pairs of milling rolls positioned in horizontal plane one above the other. Rolls of each pair rotate in opposed directions and are positioned in vertical plane at an angle of 30 deg to horizontal plane. Rolls have spring-loaded mechanisms for bringing rolls one to the other, with rolls being positioned in parallel one with the other. Rolls are further provided with ground product discharge device. Grinder has rotary electric drive mounted on base-positioning device. Drive has controlling, converting, moving and transmitting devices. Upper pair of milling rolls has transmitting device with transmission ratio of 2.5, middle pair of rolls has transmission ratio of 1.875 and lower pair has transmission ratio of 1.25. Casing has positioning device and three ready product discharge devices. Ready product may be separated and sieved. Grinder drive moving device is formed as one, three, four and six engines of different types depending on technical and economic requirements. Controlling and converting devices are designed to provide manual adjustment of grinder by electromechanical units, with quality of basic and ready product and power capacity being taken into account. EFFECT: increased efficiency, reduced consumption of power, wider operational capabilities and enhanced reliability in operation. 11 cl, 10 dwg
