<p>A kernel cracking assembly comprises two frames (12, 14) each supporting a respective one of two rollers (18, 20) between which kernels are crushed. A hydraulically operated actuator (24) acts to move the frame (12) relative to frame (14) to set the separation of the rollers. A position sensor (46) coupled to the actuator (24) forms part of a closed-loop feedback circuit which serves to maintain a predetermined separation of the rollers. <IMAGE></p> |
