Abstract

451,254. Impact pulverizers. NORDBERG MANUFACTURING CO., Oklahoma Avenue, Milwaukee, Wisconsin, U.S.A. Feb. 1, 1935, No. 3330. Convention date, Feb. 10, 1934. [Class 59] Material to be crushed is directed by a gravital or forced fall into the path of rapidly rotating beaters, the speed of the falling material being such, in relation to the speed and spacing of the beaters as to bring the falling particles fully into the crushing zone before they are impacted. The material is then directed along a restricted path against impact plates. As shown in Fig. 1 material from a bin A is deposited on a conveyer belt A<3> and is discharged down a shoot B where it is struck by the beaters of a rotor E and projected onto an impact plate G. The broken material falls on to a conveyer H and is deposited onto sieves H<11>, H<12>, the fines being carried away by a conveyer H<15> and the coarse material being returned to the conveyer A<3>. A current of air from a fan B3 may pass across the descending material in the shoot B to carry off dust&c. The pulverizer, Figs. 3, 5 comprises a rotor hub with a rim D<10> and backwardly-inclined, projecting, ribs D<12> which carry the beater plates E<7>. Sectional annular rim members E are connected together by side plates and to the ribs D<12> by bolts E<2> and spigots E<1>. The beater plates E<7> are provided with side wings E<8>, E9 which engage in recesses in the rim members E, the plates being forced into contact with the ribs D<12> by wedge bolts E<12>. The rotor bearings D<2> are mounted in rubber seatings D<15>. The impact plate G<6> is curved and is hinged at G<2> whilst the plates E<21> and E<23> are hinged at E<22>.
