  • Sieve device for separating a mixture of particulate material in components of different sizes
    Patent number: 4313823
    Abstract: A sieve device for separating a mixture of particulate material into components of different sizes has a rotating perforated sieve surface and a central, vertical shaft. The central vertical shaft is coupled to a drive set. A reaction arm is fastened to the drive set and embraces a rod mounted between brackets on the lower portions of the sieve device housing. Helical springs extend between each side of the reaction arm and the brackets so that shock loads applied to the shaft can be resiliently met by the reaction arm.
