    摘要: The invention relates to a process for the formation of pellets containing an ultra hard core coated with an encapsulating material, the process including the steps of suspending ultra hard core material in a flow of gas; contacting the ultra hard core material with encapsulating to form pellets, introducing the pellets into a rotating vessel and contacting the pellets with encapsulating material to form pellets of greater mass than the pellets introduced into the rotating vessel. The invention also relates to a pellet containing an ultra hard core coated with an encapsulating material whenever produced by a process as hereinbefore described.
