Abstract

A mixing assembly includes a main flow conduit having an inlet end and an opposite outlet, a source of pressurized air at the inlet end, a container of stucco in fluid communication with the flow conduit, and a source of water in fluid communication with the flow conduit between the outlet and the container. The pressurized air draws stucco from the container into the flow conduit, and also draws water into the flow conduit to form an atomized slurry.
