DUAL STAGE PROCESS FOR THE RAPID FORMATION OF PELLETS
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 combines the "fluidised bed" method and the "rotating pan" method and includes 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.
