Abstract: A method for granulating a particle-containing material from an industrial process includes mixing the particle-containing material in the presence of water with a material that consists of or comprises a water-absorbing and swellable organic polymer compound which is insoluble in water so as to obtain granulates.

Abstract: A process for producing a coating material for coating welding electrodes and/or for producing a welding powder which can be used in an electric welding, such as in an under-powder welding, a welding powder additive, and/or a flux additive, includes obtaining a titanium-containing by-product or waste product, such as a titanium dioxide-containing material, in at least one of a production step and a production stage during a titanium dioxide production process, such as a titanium dioxide pigment production process. The titanium-containing by-product or waste product is added and/or mixed into a coating material, a welding powder, a welding powder additive, and/or a flux additive so as to obtain a titanium-containing material mixture. The titanium-containing material mixture is processed so as to provide the coating material, the welding powder, the welding powder additive, and/or the flux additive.

Abstract: The object of the invention is to provide a method with which smallest possible quantities of a varnish coating a bottom of a can extend beyond a bottom area (30a,30b), into a wall portion (30c) provided with a decoration, in order to reduce the quantity of coating substance used and to prevent said decoration from being changed. The invention proposes a coating with a fluid coating substance, each can (30) having a can axis (102). Said cans (30) are supplied consecutively out of an inlet (4), for being supported on a supporting means (3) for at least a coating interval and for being rotated about at least one axis (100,101,102). A spraying head (15,15a) having a spraying axis (104) sprays a coating onto an outer portion (30a) of said bottom area of at least one of said supplied cans (30), said spraying being effected at a first angle (&agr;) of said spraying axis with respect to said can axis (102).
