Ion exchanger resin crushing apparatus and ion exchanger resin crushing process

Abstract

The ion exchange resin processing device (10) has a tank (12) for receiving an aqueous ion exchange resin suspension (14). A stirring device (16) is provided in tank for stirring. A grinder (20) e.g. colloid mill is provided outside the tank. A pumping device (22) is provided for feeding the aqueous ion exchange resin suspension from tank to grinder. The grinding surface of colloid mill is made from metal, metal carbide or ceramic. An independent claim is included for ion exchange resin processing method.

Description

technical field

[0001] The invention relates to a crushing device for ion exchange resins, which has a tank for containing water-containing ion exchange resin suspension, a stirring device arranged in the tank, a grinding device arranged outside the tank, and a water-containing ion exchange resin. The exchange resin suspension is conveyed from the tank to the pump unit of the grinding unit. Background technique

[0002] The use of ion exchange resins for the purification of water or sewage is known in conventional power stations and nuclear technology installations as well as in power stations. Especially in the field of nuclear technology, radioactive ion exchange resins have to be disposed of and removed at great cost. In this case methods such as drainage, dehydration or curing in an adhesive base are often used. Spherical ion exchange resins are either processed directly or ground prior to application in these methods. At this point a grinder such as a corundum disc g...
