Abstract:
Screening apparatus includes a driving a shaft (12) into a screen housing (13) having a removable closure (14) and dividing wall (15) forming an underflow chamber (16) and an overflow chamber (17). The shaft (12) supports and drives an screen (21) comprising a plate steel basket carrier portion (22) axially spaced from intermediate ring frames (23) and an outer frame ring and flange (24), all interconnected by circumferentially spaced stringers (25) to form an all-welded, integral, generally truncated-conical screen (21) cage. The cage supports a wedge wire screening surface (26). The closure (14) and housing (13) mutually support an inlet assembly (27) comprising a chute (32) feeding the water and coarse coal to the inner end of the screen assembly (21). The integral, all welded screen (21) may be replaced as a unit without refurbishment.
