Claim 0:
1. A system comprising:
a centrifuge configured to centrifugal process a flowable product, wherein the centrifuge comprises a rotatable drum defining a centrifuge chamber, wherein the rotatable drum has at least two drum parts rotatable relative to one another on a thread; and
a drum tool configured to open and/or close the rotatable drum by rotating the at least two drum parts that are screwed together via the thread, wherein the drum tool comprises
a retaining element configured to attach to a first one of the at least two drum parts;
a driving element configured to attach to a second one of the at least two drum parts; and
at least one rotation device configured to rotate the retaining element relative to the driving element together with the at least two drum parts, wherein the retaining element and the driving element each have two or more points of engagement with the at least one rotation device, wherein two or more points of engagement are arranged symmetrically in such a way that forces generated by the at least one rotation device produce a torque for relative rotation of the at least two drum parts, but no resulting force is produced that acts unilaterally on the at least two drum parts that are screwed together via the thread, and wherein the at least one rotation device comprises one or more actuators of variable length.
