GRANLUND KOF-104/106 is simple to operate and requires little training. The element tubes and coils are inserted manually. Filling tubes are lowered manually.
The actual filling of MgO is done while a motor is lifting the element tubes. The MgO is fed into the element tube between an inner and an outer filling tube. An electric vibrator hammers on the element tube, compacting the MgO.
In order to achieve the best results, every combination of element tube diameter and coil, or terminal pin diameter, requires a separate set of filling tubes. We work with as small tolerances as possible on the filling tubes, in order to get the best filling results and the best
centralization of the coil.
