Problems solved by technology

[0010] In addition, this cyclic operation has the disadvantages that it may lead to a mixture of already ground and unground spherical resins, or to material that has already passed through the grinder several times and that has only passed through the corundum grinder in the first grinding step the mix of
Such mixing results in long cycles necessary to achieve the desired particle size distribution or to ensure that each particle passes through the mill at least once
Furthermore, the mentioned solution requires the use of two tanks, thus disadvantageously increasing the contaminated surface and space requirements

Embodiment Construction

[0042] attached figure 1 A schematic diagram of an exemplary ion exchange resin pulverization apparatus 10 is shown. The tank 12 is filled with the ion exchange resin suspension 14 , the degree of filling being indicated by the line identified by reference numeral 32 . The tank 12 is made of high-quality steel and has a filling capacity of, for example, 800 L or significantly more. The upper area of ​​the tank is implemented as a hollow cylinder, while the lower area tapers funnel-like into a discharge opening. Of course, embodiments without such a taper are also possible. An ion exchange resin suspension inlet 30 is provided in the upper region of the tank, which inlet can be closed by means of a second shut-off valve 28 . It is of course also possible to provide several inlet valves so that the final suspension is only formed in the tank 12 .

[0043] Extending from the upper middle into the tank 12 is a stirring device 16 which is driven by a drive 18 on the outside. T...

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...
