  • Apparatus for spraying liquids such as resins and waxes on surfaces of particles
    Patent number: 4430003
    Abstract: To uniformly and economically disperse liquids, via sprays of droplets, on surfaces of particles, a method moving the particles involves their rotary lifting, followed by their free falling, with a spray of droplets originating from a central area of the overall motion path of the particles. In a preferred embodiment of the blending apparatus, a hollow drum is rotated about a near horizontal axis. Inside the drum, commencing at each end are cantilevered non-rotating shafts, each positioning one or more powered slightly conical discs selectively tiltable to ultimately disperse respective sprays of droplets from a central area.
