Abstract
1,203,552. Impact pulverizers. PORTEC, Inc. 26 March, 1969, No. 15794/69. Heading B2A. An impact pulverizer has fixed primary breaker bars 8, 9 Fig. I and a curtain of secondary breaker bars 11 supported by a housing 13 pivoted at 14 to the casing 1. The secondary bars are co-planar and vertical when the housing is closed. When the housing is opened by cylinder and ram assemblies 15 the bars 11 are accessible from above. The arrangement of bars may be varied by removing and replacing plates 18, 19 which secure the bars in place. The hammers 7 are rigidly attached to a rotor 2 by bolts 24 and wedge blocks 25 Fig. 2, and are further retained, in the event of failure of the bolts by eyes 30, wedge faces 32, rotor eyes 34a and bolts 26. A yieldable final breaker bar 12 is fitted in blocks 43 Fig. 7 which are positionally adjusted by shims 46. An uncrushable piece forces the bar (and consequently the shims), a back plate 47, a bar 48, a collar 51 and a shear plate 50 backwards against a tube 54, so that the centre of the shear plate is punched out by the tube. Damage to the apparatus is thus prevented.
