Thread: Another home built cyclone.

I was going to post about this further down the track when I’m more confident of what’s actually happening but thought I’d do it now as it’s similar to Heimlaga’s post.

I fabricated a cyclone starting with a cylinder from a Carbatec? dusty another member was kind enough to give me a few years back.
It had the square inlet and the inverted dish and was about 480 dia by 200 high.
I added another 200 cylinder to the bottom of it and a 1.6 ratio cone in 1mm steel.
The return inner tube was 200 and a bit longer than the cylinder.
I didn’t make a downward spiral as a mate said if I got the slope wrong it would impede rather than improve the airflow down the cone.
Mounted this above a ply box of about 100 litre capacity with a hinged front door and a plastic crate to collect the waste thru a 150 exit at the bottom of the cone.
I don’t do production or use MDF so plan to just dump the waste in our 2 compost bins.
Blower is about 14” in dia by 3” in unit with a 2hp 3ph motor, very noisy.
150 mm steel ducting to 30” disc and 150 to 20” Bandsaw with2 or 3 90mm flex pick ups.
Final few metres to 9” jointer only 125mm steel duct.
Exhaust is 150 pvc thru the wall into an old dog kennel with some foam baffles inside.
Ive only just test run this on Friday but used all 3 machines and so far there doesn’t seem to be any dust in the dog kennel at all.
I is noisy outside still and very noisy inside.
I plan to box around the unit with some 75/100 mm polystyrene foam and possibly form ply over that. The back 3m x 3m room will only have it and a compressor in it, it has 8mm thick fibro walls on 100 x 50 steel frame. I plan to stuff the walls with foam and cover with formply to lessen the noise to the neighbours.
The room will be sealed from the rest of the shed and sound insulated on that wall plus the gal iron roof.
A work in progress, not sure how it’s all going to work out in the end.
