description	The present disclosure refers to a device and a method for the addition of liquid additives in the form of a spray during a jet milling step in a process for the manufacture of sintered NdFeB alloy magnets. The device includes: a storage barrel for the liquid additive; a weighing bucket which is in fluid communication with the storage barrel and is adapted for weighing a predetermined amount of the liquid additive; a powder container to accommodate NdFeB alloy material prior to or after jet milling, wherein the powder container includes an opening that is plugged with a blind flange; a connecting pipe, which is in fluid communication with the weighing bucket and passes through an opening of the blind flange into the interior of the powder container; and a fluid atomization nozzle located at the end of the connection pipe.
