A method for controlling the operation of a continuously or periodically operating centrifuge can be employed in the sugar industry for separating crystalline carbohydrates or sugar alcohols from a crystal suspension called a magma or a mother liquor. The magma has a varying content of fine grain that is dependent on the properties of the pretreatment and of the raw material. Variable control values are provided in a control device of the centrifuge. One or plurality of sensors are provided that carry out the measurements in electromagnetic, optical, acoustic, and/or conductive ways. These measurements that are conducted serve for determining the fine grain fraction of the magma. The measurements are supplied as measurement signals to the control device of the centrifuge. The control device automatically analyzes the measurement signals supplied to it and evaluates them with respect to the fine grain content of the magma. The control device changes the variable control values of the centrifuge as a function of this evaluation.

The invention relates to a separator drum (10) with a hydraulically actuated, axially movable piston slide valve (20) which can seal off a solids space (14) from at least one solids outlet (18), wherein the piston slide valve (20) can be held in its closed position via a closing chamber (30) that can be filled with closing liquid, in particular closing water, wherein the closing chamber (30) is formed between an underside (21) of the piston slide valve (20) and a top side (35) of a drum lower part (15). According to the invention, the closing chamber (30) has a first closing chamber portion (31) near the rotation axis (R) and a second closing chamber portion (32) remote from the rotation axis (R), wherein the first closing chamber portion (31) is formed by two mutually parallel portions (22, 36) of the underside (21) of the piston slide valve (20) and of the top side (35) of the drum lower part (15), and the second closing chamber portion (32) has at least in part a conical cross section.
