Abstract:
An aggregate accelerator for sorting a material such as coal from rock is presented. The accelerator includes a housing, a grizzly, a flail assembly, an impact grate assembly and lower grate(s). The grizzly allows material of a certain size to pass through the grizzly. The flail assembly has independent paddles configured to spin generally adjacent and co-planer due to centrifugal force and hit material to be separated from rock. The impact grate assembly receives and further breaks material hit by the flail assembly. The lower grate(s) allow material of a predetermined size to pass through the lower grate(s) to be collected. The lower grate(s) do not allow material larger than the predetermined size to pass through the lower grate(s) so that this material can be discarded.
Abstract:
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.
Abstract:
A mobile coal processing unit can be loaded onto a truck and driven to an actual coal mine to break and sort coal. Once at the coal mine the mobile coal processing machine can self-propel itself to a desired location where it is to process coal. While at that location portions of the mobile coal processing machine that were folded and/or compressed for transportation are unfolded and/or uncompressed to make the mobile coal processing unit operational. The mobile coal processing unit includes a coal breaker to break mined coal into smaller pieces. It further includes a sorting device adapted to sort the smaller pieces and other mined coal into first size coal with a first size range and a second size coal with a second size range that is larger than the first size range.
