<p>A screening apparatus for screening pulp suspensions comprises a housing (2), a screen basket (8) having a tubular mantle wall with screen apertures, the mantle wall dividing the interior of the housing into a central chamber (10) and an outer substantially annular chamber (14), and a rotor (26) arranged in the housing for providing pressure and suction pulses in the suspension to be screened along the mantle wall. At least one elongate support element (52; 53) connects the screen basket (8) to the housing (2) and at least one load sensor (58; 60; 66) is arranged on the support element for sensing the load exerted by the screen basket on the support element during operation of the apparatus. During operation, a control unit (62) controls at least one operating parameter, such as the consistency of the incoming suspension or rotational speed of the rotor, in response to signals from the load sensor.</p> |
