Abstract

491,632. Impact pulverizers. PENNSYLVANIA CRUSHER CO. Nov. 1, 1937, No. 29833. Convention date, Nov. 2, 1936. [Class 59] In a hammer mill the direction of rotation of the hammer system is reversible and the inlet for the material, the breaker plates of the upper crushing stage, the screen parts and the hammer system are arranged symmetrically with respect to a vertical plane passing through the hammer shaft. As shown in Fig. 2, hammer heads 47 are pivoted on bars 45 threaded through discs 42 spaced apart by rings 43 which are fixed to a rotatable shaft 34. The hammers rotate within a cage formed by upper impact plates 11, 12 adjoining the feed inlet 48 and lower screen plates 13, 14 pivoted at 15, 16 and adjustable toward the hammers by eccentrics 27, 28. Crushed material passes through the grid bars 19 and coarse material slides over plates 23, 24 and is projected by the hammers against an impact block 32 pivoted at 33, the block being inclined as at 32a for clockwise rotation of the hammers or in the reverse direction for an anticlockwise' rotation. In Fig. 3, the grids 56, 57 are connected to a floating pivot 58 by arms 59, 60 and are connected at their upper ends to arms 61, 62 mounted on shafts 63, 64 operated by worm and wormwheel. The spaces between the grids and upper impact plates 72, 73 are closed by transverse bars 78, 79. The space 81 between the bottom of the grids is closed by a hinged flap 82 secured by a latch 88 and forms a tramp-iron recess. In a further modification the upper end of each grid is mounted on an eccentric and the bottom is supported by a link and lever arm, the trampiron space at the bottom of the grids being bridged by a pivoted plate.
