A material delivery assembly includes a delivery fitting attached to a drive shaft and including an outer wall that extends perpendicularly from a receiving surface. Apportioning slots are defined within the outer wall. A dispersion chamber is defined within the outer wall and the receiving surface. A material delivery conduit extends to a delivery port located within the dispersion chamber and is proximate the receiving surface of the delivery fitting. The material delivery port selectively delivers a viscous material to the receiving surface. The drive shaft and the delivery fitting are rotationally operated to define an apportioning state of the delivery fitting that is configured to manipulate the viscous material toward an inner surface of the outer wall. The apportioning slots in the apportioning state are configured to regulate passage of the viscous material from the dispersion chamber, through the outer wall and into a disk-shaped spread pattern.

The insert (20) is adapted to be fitted into an atomizer wheel. Each insert (20) has a longitudinal axis and comprises an inner end face (21), an outer end face (22), an external surface (23) and an internal surface (24) defining a channel (35) having a center axis (c) and extending between an inlet (25) at the inner end face (21) and an outlet (26) at the outer end face (22). At least the inlet (25) is offset from the longitudinal axis such that the center axis of the channel (35) is offset from the longitudinal axis of the insert (20). The insert (20) is adapted to be utilized in an atomizer wheel for a spray dryer for atomizing slurries of abrasive material, for instance for spray drying absorption for flue gas cleaning.

A splash plate assembly is retained in a rotary bell cup by a barbed skirt that interfaces with an inner surface of the bell cup. The splash plate assembly includes a splash plate or deflector that is secured to the front side of an insert. The insert has barbed extensions that may form a skirt around an outer periphery thereof. The insert is snapped into the front bell opening of a bell cup, and the barbed extensions elastically deform and snap back outwardly to interface with a shoulder formed in the bell cup inner surface.

A sprayer includes a sprayer body. The sprayer body is provided with a liquid material inlet, a liquid material nozzle, a gas inlet, a gas nozzle, a liquid material channel, and a gas channel. The liquid material nozzle and the liquid material inlet both communicate with the liquid material channel, the gas nozzle and the gas inlet both communicate with the gas channel, and the gas nozzle is provided at the liquid material nozzle. A dispersing member is provided in the liquid material channel and disposed at the liquid material nozzle. The dispersing member divides the liquid material channel into multiple sub-channels communicating with the liquid material nozzle.
