Abstract of the Disclosure A wear-resistant rubber product adapted to be used as, for example, a lifter in grinding mills, comprises at least two prefabricated parts interconnected with one another by means of a binder layer having a thickness of at least 2 mm and consisting of in situ cast and cured polyurethane. The wear-resistant rubber product is manufactured by placing the prefabricated cured rubber parts at a distance of at least 2 mm from one another and by introducing, preferably injecting a reacting urethane rubber composition with excess isocyanate groups into the gap to cause said prefabricated parts on either side of said gap to be contacted substantially simultaneously by the said urethane rubber composition.
