Abstract: A mixing device for outputting wet insulation is provided. The mixing device includes a nozzle and a plurality of control apertures that control penetration of a wetting material, such as foam with a binder, into insulation particles that are being forcibly moved through the nozzle. The control apertures can be used to provide a spray output and/or control the insulation density associated with the wet insulation output by the nozzle. The control apertures can be part of a primary conduit that can be adjustable or removable relative to a receiver space of the nozzle. Depending on the relative location of the control apertures in the nozzle receiver space, a desired insulation density can be achieved. Different primary conduits can also be provided having one or more of a different number of control apertures, sizes of the control apertures and positions thereof.

Abstract: A material feeder is provided that includes a drum having a number of compartments that receive material that is to be output by the feeder. The material can be any one of many different materials that are usually light and/or smaller in size, such as insulation, powders, grains and the like. At least a first seal is provided adjacent to the drum to close off an end of each compartment during some of its rotation. The first seal is preferably stationary during rotation of the drum and its compartments. The position of the seal relative to the drum can be adjusted to provide desired positioning between the seal and the drum. In one embodiment, the first seal is in contact with at least portions of the first end of the drum. The material is delivered to each compartment in the drum preferably using first and second fillers that are mounted adjacent to and outwardly of first and second ends of the drum.
