Sawdust blower

[D6c]

I'm trying to come up with a sawdust blower setup to work with the sawmill (LT40), plus a jointer & planer.
The sawmill is set up under the open side of a building and the other machines can be put inside, just on the other side of the wall.  Would rarely be running more than one machine at a time.
It would be my intention to blow the dust into a wagon.

Not sure if it will also require a cone to spin the dust out of the air and drop it down of if I can get away with just a blower.

Something like this is about what I'm thinking, but I don't seem to find that particular one available.

Looking for recommendations on models and sizing....something that works but won't break the bank.
Thanks

We use a Timber King 5 hp to service the mill, planer, SLR and the edger, two at a time. The bare blower exhausts into a cyclone plumbed in reverse ( pressure instead of vacuum) and the sawdust and chips fall out of the down tube into a self dumping forklift hopper. Works great
We tried not using a cyclone for years but the sawdust shoots out like a snowblower, and we could barely get it to hit into a dump truck bed.

X2 on the Woodmaster unit YH speaks of. I use one for my 25" planner and 4 head moulder, the sawmill will be hooked up to the system here shortly. The moulder makes a mountain of shavings and that unit handles them with no problem. They run about $900 and use 240V 50 amp single phase.

Thanks, I'll have to talk to TK.

Don't know anything about cyclones...can anyone point me to a place to look?

I got mine from Oneida, the 8" version metal, commercial grade.  Only the cyclone itself is needed, nothing else. As a mentioned, I am running it backwards, attached to the pressure side of the blower, instead of the vacuum side.  The reverse configuration works better than I had hoped. 

Since the air and sawdust mix is being sucked into the TK blower, there are two options for capturing the sawdust when it comes out.  

Picture 1 is a straight pipe blowing the sawdust into and over a dump wagon.  Huge mess.  I also used a bigger bed on a dump truck, but still a huge mess.  Lots of sawdust in the ground.  The pipe can't be pointed directly into the catch bin because there is so much airflow, it simply blows everything out.  


This picture is when I mounted the cyclone to the exhaust pipe.  The sawdust spins out and falls out the bottom pipe like sand from an hourglass, while most of the air goes out the top.  Much better.

YH, I don't see a dust collector on Timber King's site?

The TK and Woodmaster are the same blower, apparently the two companies share the product, is what they told me.  Here's the link the the blower.

I've got the 5 hp, no bags, no nothing except the blower and the contractor switch which will save a few bucks.  Get them to put enough power cord on it so you can mount the blower outside, high up under an eave so you don't have to listen to it, and so the cyclone has room with a drop pipe into a bin, and so the switch is inside next to your tool.  
This is a heavy duty unit, we run our all day, every day, and it just keeps working.

All my sawdust except the walnut, is blown into a silage wagon with roof. At first it didn't work and I considered a cyclone. The wagon is enclosed except the upper half of the front. The trick was to keep the delivery pipe just out side the wagon.

Have your blower pipe enter the mid line of a vertically oriented 55 gallon drum (with both ends gutted) at a tangent so as to follow the peripheral wall.   Bind household window screen over the open top with a bungee cord and let bottom dump into your containment of choice.  You can taper the bottom to a convergent nozzle with tin and rebar or bed frame etc if you want.  It doesnt have to be round.  All you need is to induce a swirl that will dissipate the energy of the heavier particles so they can fall out of suspension.

Trashbags at the bottom can work if youre giving the stuff away as animal bedding or speedy dry or something like that.  KD sawdust and oil are an excellent stove starter.  I gave away a few buckets to family and friends and they all stuck with it.
