ABSTRACT:
A screening machine including at least one screen surface, feeding means that feed material to be screened towards the screen surface and onto the screen surface where the material is separated into a first fraction remaining on the screen surface and into a second fraction passed through the screen surface while the material is moving along the screen surface. In a method for controlling the screening machine, the amount of material on the screen surface is determined by automatic measurement, and the speed of the feeding means is controlled on the basis of the measurement by automatic control.
