Abstract:
A blender continuously receives a plurality of components from material hoppers, continuously blends the components together at a preselected ratio, and discharges the blended material to a blended-material feeder which continuously discharges the blended material at a controlled rate to associated apparatus. The blended-material feeder is regulated to continuously discharge the blended material at a rate substantially equal to the summation of the rates of the material components entering the hopper.
