Abstract
The rotary atomizer disk has an upper part and a lower part connectable to the upper part using a plurality of screws. The disk comprises a number of atomizer nozzle insert receiving holes for receiving a corresponding number of nozzle inserts from outside the disk, and a number of screw receiving bores passing at least partially through each of the insert receiving holes for receiving the screws connecting the lower part to the upper part. In this way, by removing any one of the screws, a corresponding one of the nozzle inserts can be removed from the disk without disassembling it. The inserts may be symmetrical and be turned or reversed to be reused. The invention avoids the need to rebalance the disk after disassembling for nozzle replacement purposes.
