Abstract
A dispensing device for powder coating material includes an outer device portion having a first inner surface and a central passageway for mounting the outer portion on a rotary shaft for rotating the dispensing device. An inner portion of the dispensing device has a second outer surface shaped complementarily to the first surface and a somewhat bell- or cup-shaped third inner surface. Threaded fasteners retain the inner portion in the outer portion with the first and second surfaces in engagement. The outer portion is constructed from a first material having mechanical strength to withstand the stresses attending rotation of the dispensing device. The inner portion is constructed from a second material relatively more inert to the movement of the powder coating material across the third surface.
