ABSTRACT:
A multiple-roll roller mill, useful in particular for livestock feed processing, is disclosed. The mill includes a main roller and at least two secondary rollers, each secondary roller opposing a different axial portion of the main roller circumference and thereby defining axially separate mill sections. Each secondary roller is independently adjustable towards and away from the main roller. A chain and sprocket arrangement gangs the adjustment means for opposite ends of each secondary roller to ensure that the rollers remain parallel when adjusted. Pressure springs urge the secondary rollers toward their adjusted positions, but allow movement away from the main roller when the spring pressure is overcome. A chain drive is employed which includes moveable idler sprockets arranged so as to maintain relatively constant chain tension when the roller positions are adjusted.
