Abstract Apparatus for preparing ashes in a crematory includes a casing to the lower end of which can be fastened an urn for receiving the ashes after they are ground in a rotatable drum located within the casing. An ashpan from the crematory oven containing the ashes is inserted into the interior of the drum by way of a door on the casing, and when the drum rotates, the ashpan is turned upside down thus spilling the ashes into a perforated shell located within the drum and containing rolling bodies for grinding. The ground ashs pass downwardly and outwardly through the perforated shell and thence into the attached urn. In another embodiment, the ashpan itself forms part of the rotatable drum structure to which is attached a perforated cover, the rolling bodies for grinding being placed inside the ashpan before being inserted into the enclosing casing.
