Abstract： In order to decrease the running rough of powder products caused by failure of the separator seal and improve the quality of final products, the principle of seal methods for separator was analyzed and its characteristics and shortages were pointed out. Against the problem of running rough caused by failure of separator seal, the plane and roundness detecting principle of the separator dynamic seal parts were suggested. The simulating and dynamic seal detecting device was designed and the detection of seal parts was simulated. The shape-position error detection of the separator sealing device convex and concave groove was realized. The simulation and application results showed that this dynamic sealing and detecting device was very efficient to solve the running rough of powder products caused by failure of the separator seal.
