Abstract
A cylinder mill for grinding grains and other granular products includes an overdrive mechanism for effecting varying rotation speeds. The overdrive mechanism includes a belt tightener and tightening pulley. The tightening pulley has two sections that are separately adjustable to achieve different tightnesses. This permits an essentially constant tension in the belts comprising the overdrive mechanism such that the belts can operate smoothly.
