The function of all kinds of powder filling machines are the same,and the goal can be summarized as “center,solid and fast.”
Center means after filling the powder,the resistance wire must be guaranteed in the center of the metal tube.
Solid means the filling density of magnesium oxide powder must be high.
Fast means that the process operation is simple,fast and efficient.
Powder filling density could be above 2.17g/cm3.
Almost zero MgO loss.
Filling speed 100~1500 mm/min
Min. coil diameter 1.5mm
Vibration frequency variable 25~35hz
Min. tube diameter:5.5mm
Bottom stand for the element tube
Stand with motor and clutch
Control box with frequency converter
Cable connection between control box and machine
Equipment for filling cartridge heaters(optional)
Equipment for filling elements with 2,3 or 4 coils(optional)
The difference among the three types of machines
TF01 Filling machine often used for short tubes,max. 3 meters long,It is the most economical one.
TF02 Filling machine uses two filling tubes,like Kanthal type with jet nozzle.It is also applicable to aluminum double-tubes.
TF03 Filling machine has all the best benefits of all filling machine. Three filling tubes has been used. One inner and two outer tubes. One of the outer tubes work as a sleeve.It is often used for very long and large diameter tubes.
