The invention relates to a method of manufacturing encapsulated superhard material, the method comprising the steps of providing a source of superhard material, providing a mixture comprising an appropriate binder, a solvent or fluid medium and the intended coating or encapsulating layer, combining the superhard material and the mixture in a shovel rotor comprising a vessel including a rotor, the vessel adapted to receive a stream of gas; and rotating the rotor at an appropriate velocity such that the superhard material is encapsulated by the mixture. The invention further relates to an encapsulated superhard material produced by a method as hereinbefore described.

Cette invention a trait à un procédé de fabrication d'un matériau extra dur encapsulé, ledit procédé comprenant les étapes consistant à fournir une source de matériau extra dur, ainsi qu'un mélange comprenant un liant approprié, un solvant ou un milieu liquide et l'enrobage ou la couche d'encapsulation choisi(e), puis à combiner le matériau extra dur et le mélange dans un rotor à pales équipé d'une cuve à rotor, la cuve étant adaptée pour recevoir un courant de gaz ; l'étape suivante du procédé consiste à faire tourner le rotor à une vitesse suffisante pour que le mélange puisse encapsuler le matériau extra dur. L'invention concerne par ailleurs un matériau extra dur encapsulé et produit par un procédé énoncé dans la description.
