Continuous mixing apparatus with upper and lower bladed disk impellers and a notched blade

Continuous mixing apparatus comprising:

• an upper bladed disk turbine impeller and a lower bladed disk turbine impeller, the impellers being located in a mixing chamber of a casing, the impellers being mounted for independent rotation with respect to one another;
• an upper ring shaped baffle extending radially inwardly from the inner wall of the casing between the upper bladed disk turbine impeller and the lower bladed disk turbine impeller, the baffle being arranged out of contact with the impellers;
• a lower ring shaped baffle extending radially inwardly from the inner wall of the casing and into a cutout portion in the blades of the lower bladed disk turbine impeller so as to be in non-contacting relationship therewith;
• the mixing chamber of the casing being divided by the upper bladed disk turbine impeller, the upper ring shaped baffle, and the lower bladed disk turbine impeller, into an uppermost mixing chamber, an upper mixing chamber, an intermediate mixing chamber, and a lower mixing chamber;
• the upper part of the casing being provided with a material loading opening for loading materials of different types into the uppermost mixing chamber;
• a liquid supply pipe passing through the side wall of the casing into the intermediate mixing chamber or into the lower mixing chamber for supplying liquids into the chambers;
• and a discharge opening in the bottom of the mixing chamber for unloading the mixture from the mixing apparatus from the lower mixing chamber.
