Method and device for the grinding and separating of grain

A grain husker has two decorticating rollers which are accommodated in a housing, one of the rollers being rotatable about a stationary axis, while the other roller is mounted on a carrier which, in turn, is mounted on the housing for pivoting relative thereto in such a manner that the movable roller moves with the carrier closer and farther away from the stationary axis of the first-mentioned roller. A drive for the rollers includes a motor, a driving pulley mounted on the output shaft of the motor, and idler pulley and a driven pulley of the movable roller, all of these components being also mounted on the carrier for displacement therewith, the drive further including a driven pulley of the stationarily mounted roller and an endless element which is trained about all of the above-mentioned pulleys. The driving and idler pulleys, as well as the driven pulley of the movable roller are located in the corners of an imaginary triangle, while the driven pulley of the stationarily mounted roller is located within the imaginary triangle so that the required length of the endless element will always be the same irrespective of the amount of displacement of the movable roller with the carrier within the working range thereof. Thus, as the decorticating rollers wear off, the movable roller will move closer to the stationary axis due to the weight of the components mounted on the carrier or acting thereon, and there is no need for retensioning the endless element during the movement of the movable roller within its working range.
