Concentric ring fluidized mixer

A mixer with a unique rotor, suitable for mixing 6-15% pulp (medium concentrate) with a gaseous bleaching aid (containing about 6% ozone), the rotor has a disc-shaped bottom, in the middle of the chassis Connected to the motor via a hub-like device, the motor rotates at a speed of 1000-6000 rpm, and one or more rings concentric with the chassis extend approximately three inches (height is also different). A certain number of blades extend radially outwardly from the chassis, the ring and the hub through the center of the chassis. There is a deaeration hole in the hub, which is connected to the degassing device of the mixer. These rings have a certain shape, and the rotor is installed. In a chamber with an inlet and outlet of pulp, a space is formed between the stator and the rotor, the distance between the stator and the rotor surface is 0.5 inch or less (usually 0.25 inch or less), and the fluid mixed with the slurry passes through The entrance to the rotor enters the mixing zone.
