For magnetic filtering of small amounts of ferrous contaminants from dusty, free-flowing powders in free-fall transport pipes.The automatic cleaning makes this type suitable for situations where the magnetic separator is hardly or not accessible for operation and cleaning.Industrial finish - grit blasting Ra 3 µm

Automatic cleaning (discontinuous)
2 magnetic grids, placed in cascade
Magnetic bars in pneumatic tube (Ø25 mm, 11,000 gauss)
Dust-proof
ATEX II 1/2 D

Application

Dusty powders in free-fall pipes

These automatic, discontinuously cleaning, dust-proof Cleanflows are especially suitable for dusty powders with a small amount of ferrous impurities.
 
Also suitable for non-dusty powders & granulates, but NOT for sticky powders that cause blockages. For those applications the rotating versions of this type Cleanflows are a better solution.
 
The automatic cleaning makes them suitable for badly accessible situations.

Working principle / video

Filtering & discharging of ferrous contaminants

How does the magnetic filtering work?
Each magnetic bar has a magnet package that pneumatically moves inside a closed tube, this way automatically discharging trapped ferrous particles.
 
After you have stopped the product flow and have given the start signal for cleaning to the control, air pressure automatically pushes the magnets out within their enclosing tubes.
 
The moving magnets in the tubes pull the captured ferrous particles along outside. However, they are stopped by a plate halfway the tube length. As soon as the magnets have traveled completely out, the captured particles drop off the tubes, into the iron discharge chute, where you collect and further discharge them.
 
Cleaning / iron discharging sequence

Stop the product stream
Give start signal to the magnet's control unit

Now first the valve in the valve box is automatically switched to iron discharge position
Then the magnets inside the pneumatic tubes are moved automatically out of the product channel
The captured metal particles want to 'travel' with the magnets, but are held by retainer rings on the magnet bar tubes. As soon as the magnets are out of reach, the captured particles automatically drop off of the tubes, into the valve box, where they are discharged further
Then the magnets inside the pneumatic tubes are moved automatically back into the product channel
When the magnets are all back in, the valve will automatically be switched back to its production position
As soon as the magnets and valve are back in production position, the control will give a 'ready for production' signal
You can now safely resume production
