ABSTRACT:
In the manufacture of chip board panels, the chip parts are sprayed with a bonding agent, and in the subject process, a curtain of chip particles of rotational symmetry relative to a vertical axis is first coated with the sprayable binder, after which the particles fall onto a generally horizontal rotating plate, whereby the particles are deflected and slung outwardly where the particles are again exposed to the effect of the spray jet. Thereafter, the particles are deflected downward for further treatment or collected and removed. The apparatus includes a circular particle delivery part for the formation of the rotationally symmetrical curtain, a spray device arranged within the curtain and concentric to it, and a rotating plate supported concentrically to the axis of the curtain particles and spaced away from the feed point of the particles. The assembly is disposed within an outer housing whereby after the particles are deflected and slung outwardly, and again passed through the spray jet, the particles are then deflected downwardly for further treatment or collection.
