ABSTRACT:
A roller or brush for cleaning meshes of rotary screens, comprising a shaft having one or several cleaning members each comprising a body of revolution consisting of two concentrically arranged portions. The outer part in contact with the screen surface is of a stiffness several times greater than the stiffness of the inner portion adjacent to the shaft so that dynamic load at the contact of the brush and screen is several times lower, the efficiency of cleaning of meshes of the screen is improved and the service life of the screen is substantially prolonged.
