SCREENING-CASTING METHOD AND DEVICE; PREPARATION OF A CLOSE MIXTURE OF POWDERY PRODUCTS

摘要

The invention concerns a novel method for screening-casting of powdery products, designed to provide said products with a particle-size range having a narrow distribution principal mode centered on a value of several tens of microns and a fraction of micronic particles. The invention also concerns a device for screening-casting of powdery products designed to implement said device. The invention further concerns a method for preparing an intimate mixture of at least two powdery products, the mixture being called intimate in that it consists in a mixture on micronic scale. Said preparation method comprises said screening-casting method. It is particularly, but not exclusively, suited for the production of nuclear fuel pellets.
