Continuous mixing apparatus with upper and lower disk impellers each having scrapers

A continuous mixing apparatus comprising a casing;

• an upper rotary disk and a lower rotary disk capable of being rotated independently, disposed in a mixing chamber within the casing;
• a plurality of scrapers attached to upper and lower sides of upper rotary disk and to the upper and lower sides of lower rotary disk;
• an upper ring plate extending from the inner wall of the casing between a lower one of the scrapers of the upper rotary disk and an upper scraper of the lower rotary disk;
• a lower ring plate extending from the inner wall of the casing in a lower portion thereof, the scrapers on the lower side of the lower rotary disk having a notch enabling the scrapers on the lower side of the lower rotary disk to pass over the lower ring plate;
• the mixing chamber inside the casing being divided by the upper rotary disk, the upper ring plate, and the lower ring plate, into an uppermost mixing chamber, an upper mixing chamber, a middle mixing chamber, and a lower mixing chamber, respectively;
• material supply ports in the upper portion of the casing for supplying different types of materials to the uppermost mixing chamber;
• a liquid supply port for feeding replenishing liquid, the liquid supply port extending through the side wall of the casing to the middle mixing chamber or the lower mixing chamber;
• and a discharge port in the lower mixing chamber for discharging the mixture of materials.
