Abstract
491,184. Impact pulverizers. PENNSYLVANIA CRUSHER CO., and HARTSHORN, S. D. Dec. 8, 1937, No. 33983. [Class 59] In an impact pulverizer the pivotal arrangement of beater rings or beater shank on the rotating disc is such that on meeting an obstruction the ring which normally pivots on a rod 42 leaves this pivot and rotates on a pivot 43 nearer the circumference of the disc. The pivots 42, 43 may form part of a cam surface. As shown in Fig. 1 discs 39 are mounted on a rotatable shaft 30 the rings 44 being held on the two rods 42, 43 on the discs. The disc 30 rotates clockwise and when the ring 44 strikes the material it pivots on rod 43 and moves inwardly away from rod 42. The mill casing is provided with a breaker plate 12 and a tramp iron recess 15. The grating 20 comprises bars 19 held at their ends in grooves in curved members 18 pivoted at 21 and adjustable toward the rings by an arm 23 mounted on a shaft 24. The rings may be of various shapes externally and internally and be provided with a toothed circumference. In Fig. 6 the rings are mounted on a cam surface 50 having lateral flanges 50<1>. The rod 42 may comprise the rotatable shaft 30 and in Fig. 14 a pivoted hammer 84 is mounted on a cam 61 fixed to the drive shaft.
