The R series planar rotary screen, also known as the planar gyratory screening machine, is a high - capacity, high - precision, and high - standard screening machine. It combines advanced American technology and R & D experience, and has been improved and designed to adapt to international production conditions. This equipment is currently the most effective screening machine that simulates the principle of manual screening movement. It can separate all powders and particulate materials in the fine and ultra - fine range. It is especially suitable for screening some materials with special material properties, and all screening indicators are better than those of general screening equipment.
