ABSTRACT OF THE DISCLOSURE To uniformly and economically disperse liquids, via sprays of droplets, on surfaces of particles, a method of moving the particle involves their rotary lifting, followed by their free falling, with a pray 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 drop- lets from a central area. This central area is defined by particles being lifted while centrifugally held to the interior of the drum and then at a zenith locale the gravitational force becomes effective enough so the particles drop in an arcuate cascade path back to the interior surface of the drum to start another cycle. The cycles are predetermined to continue until the particles acquire the selective quantity of dispersed droplets on all of their surfaces. Then the particles leave the interior of the rotating hollow drum opposite the end of their entry into the drum. This method and apparatus is parti- cularly useful in treating with liquid resin binders, and/or wax emul- sions, thin wood wafers, wood flakes, wood shavings, sawdust and other particles of like respective sizes, which often are subsequently collectively formed and pressed into products, such as wood wafer boards.
