First, it is compressible and cushiony ; second, it can be transported to a long distance with a little power loss ; the last, its flux and velocity of flow are quite high, so the reaction time of the operators can been considerably shortened. aiming to solve the problems of vibrating machinery such as short life - span, poor cushion and high energy consumption, the writer, on the basis of characteristic of pneumatic mentioned, contrives a set of valve controlled pneumatic vibrator, which has larger output vibrating force and longer life - span with simple structure. then, it is applied to drive a vibrating screen and the result is fairly well
