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

摘要

A continous mixing apparatus has an upper rotary disk and a lower rotary disk able to rotate independently of one another. A plurality of scrapers are attached to the upper and lower sides of the upper and lower rotary disks. Scrapers on the lower side of the lower rotary disk have a notch enabling the scrapers to pass over a lower ring plate in the mixer. Material to be mixed is supplied to an upper portion of the mixer, and the product is discharged from a lower portion of the mixer. The device is constructed to enable any subsequently replenished liquids to not rise to the top of the mixing apparatus. The device produces a mixture that is uniform, highly stable, and that has a small particle size or a low viscosity which can be manufactured quickly.
