AGGREGATE BREAKER AND SORTER WITH MODIFIED GRIZZLIES

摘要

An apparatus for sorting a material such as coal from rock is presented. The system includes a housing, a grizzly, a flail, an impact grate and lower grate(s). The grizzly allows small pieces of material to pass through the grizzly. The grizzly includes elongated grizzly bars that are wider at their upper ends than lower ends so that tapered openings formed between the grizzly bars are wider at the lower ends than the upper ends. The flail has paddles that spin and break material not passing through the grizzly. The impact grate receives and further breaks material hit by the flail. Lower grate(s) allow material of a predetermined size to pass through them to be collected for further use while at the same time not allowing material bigger than the predetermined size to past through them so that this unwanted material can be disposed of.

主权项

1. An aggregate breaker and sorter comprising:
a housing; an inclined grizzly assembly inside the housing to allow material of a certain size to pass through the grizzly assembly; wherein the grizzly assembly further comprises:
a plurality of elongated spaced grizzly bars having upper and lower ends forming tapered openings between adjacent grizzly bars, with said openings being wider at the lower ends than at the upper ends; a flail assembly with a plurality of paddles inside the housing for moving and accelerating the material as it moves along the grizzly assembly; an impact grate assembly inside the housing to receive and break material moved by the flail assembly; and at least one lower grate to allow material of a predetermined size to pass through the at least one lower grate to be transported to a wanted material location, and wherein the at least one lower grate does not allow material larger than the predetermined size to pass through the least one lower grate so that this material can be discarded.
