ABSTRACT:
A volumetric batcher is combined with a batch mixer so that similiar batches of powdered fluidizable material such as fly ash can be mixed with constant quantities of water resulting in mixtures having the same moisture. This enables their disposal at a land fill site or the like. To insure that the material in the batcher is settled to the desired degree before the inlet valve is closed, a high level indicator is provided which jogs the inlet valve to retard the rate of flow and this valve is allowed to continue to jog until a short period of time has elapsed during which the high level probe is constantly under the influence of the fly ash, at which time it is completely closed. Additional means are provided for insuring complete discharge from the batcher, measuring and timing the flow of water and removing air from the mixer and batcher during charging operations.
