Abstract
746,185. Roller and roller-and-breast mills. SCHOFFEL, L. Feb. 23, 1953, No. 5051/53. Class 59. [Also in Group XXIX] The friction bar 10 of a roller-and-bar mill is loaded both at its front and its edge by sets of hydraulic cylinders 14, 15. The hydraulic pressure supply to each of these from a common pump can be adjusted separately by buttons 41 which adjust the load on relief valves 35. The invention may also be applied to roller mills, the rollers being loaded to different adjustable pressures.
