A grinding wheel drive motor, not shown, at the back of the machine, drives the grinding wheels through a pulley 26 (FIG. 4), which includes a conical pinion 27. The pulley rotates freely with respect to the transfer shaft 9. This pinion 27 drives a pair of gears 29 mounted on shaft 28 (FIG. 5) each gear having conical and helical gear teeth.
Different signs of the transfer coefficients in the orientation angles of grinding machine headstocks in the matrix make it possible to mutually compensate for the overall impact. The calculations have shown that the accuracy of the side-end machining is largely affected by a change in the orientation angle in the vertical plane.
Construction of Grain Grinding Machine ABSTRACT. The aim of the project is to construct a domestic grain grinding machine to be powered by electric motor through pulley and belt transmission. The project is to perform mostly blending and grinding on grains e.g beans, maize, melon, millet and such other food crops.
