Abstract
Abstract A CONTINUOUS BLENDER FOR MIXING MATERIAL SUCH AS POWER, GRANULAR MATERIAL, ETC., EMPLOYING A GENERALLY HORIZONTAL CYLINDRICAL HOUSING WITH AN INLET AT ONE END AND AN OUTLET AT THE OPPOSITE END. A SERIES OF SPACED-APART BAFFLES ARE POSITIONED IN THE HOUSING TO FORM A SERIES OF WEDGE-SHAPED COMPARTMENTS, EACH BAFFLE BEING CUT TO PERMIT ADJACENT COMPARTMENTS TO COMMUNICATE WITH ONE ANOTHER. AS THE HOUSING IS ROTATED, MATERIAL IS CAUSED TO PASS FROM ONE COMPARTMENT TO ANOTHER TOWARDS THE OUTLET, AND DURING ITS PASSAGE THROUGH THE HOUSING THE MATERIAL IS CONTINUOUSLY TUMBLED WITHIN EACH COMPARTMENT.
