The coupling is light, compact, and achieves a low moment of inertia. It is available in single and doublecardan designs. The backlashfree shafthub joint can be implemented in two ways: for one, by using a clamping ring hub for the frictiontype connection. The hub structure is rotationally symmetrically and suitable for high speeds.

CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

On request of the customer the RADEX®N couplings can be balanced. For usual applications this is not necessary due to the accurate machining of the coupling. Please consult with KTR, if necessary. Safety regulations: The coupling must be selected in a way that the permissible coupling load is not exceeded in any operating condition.
