This gate features a simple structure, flexible operation, light weight, no jamming, and quick cutting. It is particularly suitable for various non-sticky solids, powders, and granular materials smaller than 10mm in particle size, for conveying and flow regulation of granular materials. Installation is not restricted by angle. The operation is convenient, allowing for immediate adjustment of the opening. It is mainly composed of parts such as the frame, sliding plate, screw, nut, etc. By turning the handwheel, the screw drives the screw nut and sliding plate to move back and forth horizontally, achieving the purpose of opening and closing the gate.
