Abstract
672,009. Edge-runner mills. P. H. I. ENGINEERING, Ltd., (Engler, O.). Dec. 12, 1950, No. 30332/50. Class 59 A grinding mill of the edge-runner type has rollers 15 with shafts 17 guided directly in slots 19, 20 in a concentric pair of interconnected rotating rings 21, 22, the rollers being pressed against the grinding table 4 by a non-rotating ring 26 loaded by springs 28. Brackets 27 prevent the ring from rotating, while allowing vertical movement, and the spring pressure can be adjusted by varying the position of a further ring 25. Coal or other material to be pulverized is delivered by a nozzle 29 and pivoted shoot 30 to a grinding trough 14 formed in the table, or in a ring 12 located on the table by tongues 13, and is removed by air entering at 40 and carrying the ground material to a classifier which returns insufficiently - ground material to the table. As shown, the outer ring 21 is rotatable on rollers 31 on the mill housing but, in a modification, the inner ring 22 is supported at two points on a central bearing on an extension of the grinding table shaft and collars are fitted on the roller shafts to prevent lateral movement. Air under pressure is introduced into the central bearing through a bore in the table shaft to prevent the entrance of dust.
