FIELD: process engineering.SUBSTANCE: invention relates to distribution of particles over the surface of wood-particle boards or impregnated materials. Device to distribute particles over the surface comprises roller-like distributor with curved rubber-coated surface. Besides, it incorporates the roller-like distributor lengthwise oscillation actuator to make particles move from distributing hole over curved surface downward to surface to be dusted. It includes at least one controlled reflection plate to influence particle spraying over the surface and into airflow. Proposed method consists in using particles distributor and container with particles and oscillating the roller-like element in lengthwise direction to make particles move from distributing hole over curved surface downward to surface to be dusted. Roller-like element does not turn about its lengthwise axis.EFFECT: better control over distributed particles amount.21 cl, 3 dwg |
