Abstract (en)

In a plaster spraying machine (1), the particles of a cement mix are screened and sized by means (2) comprising a supporting frame (11) secured to the pan (3) that contains the mix during operation, and affording an internal conditioning chamber (15a) of which the top part connects with an inlet (16) in receipt of the mix and the bottom part discharges into the pan (3); the sizing action is produced by a pair of mutually tangential profiled rollers (19) positioned internally of the chamber (15a), which are supported rotatably by the frame (11) in such a way as to turn on parallel axes spaced apart at a selected distance one from the other. One of the two sizing rollers (19) is coupled to a motor (29), and the two rollers themselves are also permanently interconnected by a transmission link (22) in such a way as to rotate in mutually opposed directions when the motor is activated. <IMAGE>
