Abstract
A roll crusher having a box-like main frame, a material inlet and material outlet, a first rotatable crushing roll on the frame and a second rotatable crushing roll mounted on a roll carriage in an opposed, spaced apart relationship to the first crushing roll defining a material crushing gap. The roll carriage is a generally rectangular frame positioned atop the main frame having one end attached to the main frame near the midpoint of the main frame by pivot. The pivot is asymmetrically positioned relative to the axes of the crushing rolls. An actuator between the main frame and the free end of the roll carriage moves the roll carriage about the pivot to adjust the gap between the first and second rolls. The jack can be equipped with a servo motor responsive to a computer program.
