Abstract: A separator and method is provided for separating used bedding material into waste material and bedding material for re-use. The separator may comprise a frame, a plurality of elongate screening elements fixed to the frame and oriented in-line with a discharge end of the separator, and a rotatable actuator aligned transverse to the plurality of elongate screening elements. The rotatable actuator may have a non-circular cross-section and positioned such that when the rotatable actuator is rotated a greater radius portion of the cross-section is located to cause the plurality of elongate screening elements to deflect from a static position away from a rotational axis of the actuator, and a lesser radius portion of the cross-section is located to permit the elongate screening elements to return to the static position.
