Abstract: Method for irradiating granules, in the case of which the granules are arranged in a sample container (2) and are irradiated with an irradiation lamp (3), the granules being periodically mixed during the irradiation such that different surfaces of the granules are irradiated. It is preferred to make use for the irradiation of a device which comprises a. at least one irradiation lamp (3), and b. at least one sample container (2) for the granules to be irradiated, the sample container being connected to a drive so that the sample container can be moved during the irradiation and the granules can be mixed.

Abstract: The invention describes a novel production process for coated particles composed of granulated-rubber material, the coating, the particles coated therewith and the uses of the coated particles. The coating formulation is solvent-free.

Abstract: Rapid test to ascertain the effect of irradiation on the abrasion of a granule, in which i.) the abrasion of the granule is determined before the irradiation, ii.) the granule is irradiated, iii.) the abrasion of the irradiated granule is determined, characterized in that, the abrasion is determined by a) grinding the granule in a cutting mill, b) subjecting the ground product to a screening analysis and c) comparing the result of the screening analysis with at least one reference value, in order to classify the abrasion of the granule, the granule is irradiated by arranging a plurality of granule particles in a sample container (2) and irradiating them with an irradiation lamp (3), the granule particles being periodically blended during the irradiation so that different surfaces of the granule particles are irradiated.

Abstract: Fast test for determining the abrasion of granules, in the case of which i.) granules are milled, ii.) the milled product is subjected to a sieve analysis, and iii.)the results of the sieve analysis are compared with at least one reference value in order to classify the abrasion of the granules, the granules being milled in a cutting mill.

Abstract: The method describes a novel production method for coated particles made of rubber granules, the coating, the particles thus coated, and the use of the coated particles.
