a powder dosing system for not easily flowing cohesive and adhesive powders with a feed hopper , a discharge device , a conveying device , where the discharge device has an inclined vibrating floor , and where the discharge opening from the feed hopper and the discharge opening of the discharge device are arranged relative to each other in such a manner that a reliable and relatively precise dosing of the problematic powdery materials is possible without jamming . this is accomplished by also taking into account the specific angle of repose of the material in question . with the help of a special design of various conveying devices , such as a conveying container for discontinuous dosing and a bucket wheel lock for continuous dosing , the system can be optimized .
