You may have too design your own wood chipper for bigger chunks- but hopefully you wont have too. though it would be saleable and useable for all the wood gas drivers.

I am thinking this way for screening. First things first, a gasifier

Im going to build a tumbler dryer much like this. The plan is the use a 55 Gal drum with removable lid. Then cut the mid section out and put expandemetal in its place. The on the lid end there will be a set of rollers ( prabably the same wheels we use on the gasifiers) to cradle that end. Then the closed side there will be spindle / shaft set up with a belt drive from windshield wiper motor. This be set on a timer
You then fill it, put the lid and turn it on. The motor will advance 90* or so every fifteen minutes or what you set the times at and just let it run until the fuel is dry. But this will also get the fines and dirt out.
I think I found where clinkers come from. The batch of charcoal I fed chips into the process and those chips were full of dirt. Ran that in the gasifier last night and she clogged right up and gas exhaust was extremely hot. So Im suspecting its full of clinkers.

Today i did my first gen run on a free gen i found on the side of the road, using my ammo can gasifier. the vid is cut down fro over an hour long task. i finally got it to run stable by adding a diy 3/4 butterfly valve. Very exciting time…

I think you missed this deal. the powered cart has the holes in it to dump chips right in and do the sorting at the same time.

Stephen Abassas(?) tried it with the small disk chipper and couldn’t get it to work. No one at the time made a small drum chipper. What I recall is he put small wedges in there because the blade has to rest on the drum. I think he actually snapped the bolts on one try. That is when he moved to the PTO version.
But the drum is what you want if you want the small chipper.
And to be quite honest the russian screw chippers are probably the best. small chunker design.

Dirt forms much slag/clinker just as you said, this was a common problem during war-time, in scandinavia it was common to make charcoal in charcoal “mounds”, stacked wood covered with dirt to control combustion air, charcoal from these gave enormous amounts of clinker, need to cleanout gasifiers atleast every day.

Do the drum type chippers just work better on their own merit or do they also have to be modified?
Also, is this one a drum type or a plate type? I would think this is drum type because the feed is perpendicular to the driveshaft of the engine.
Yeah that is drum style. Yeah the in and out feeds are oriented differently and is how you can tell what one is what. I Think this one you showed is made by the same company that makes the one I ordered. I just liked the feed hopper on the one I got better. Other than that they look pretty much the same.

Yeah this is first time Ive seen a drum style this small. This maybe a game changer for us.

drum chippers are the type that make what we in North America refer to as chips.
I don’t know if these small ones have to be modded at all or even can produce big enough chips. I haven’t seen any chips from it. It just has a better chance. There is a physical limit because of the drum size as to how big of chip it can produce.
Landworks is made in china, so I am guessing that the SuperHandy is the same one, and there might be a few more cheaper brands floating around available on other sites.

Ok tore the DXF-10 apart and installed the new eccentric reactor core and installed our grate system with actuator. This grate set up be standard instead of the bought grate. The automation and agitator motor will be sold seperatly but in standard form the arm can be used for manual opperation. Plus it will be easier to service. There is a lock collar that holds the grate in place. To drop the grate to clean out the reduction system. You just unlock the collar and slide the grate down. It will with the agitator installed as well.
One the best parts of this machine is it is really easy to work on. By far best machine as far as servicing goes.

When I inspected the layers I really did not see any real issues with the the recuction. Other than it had some dust accumulation it was not too packed. No clinkers at all here. I did find some small ones and that was due to some actual metal that made its way into the fuel. The only thing I found was at the restriction throat, it was like dust all fused together there. I have to assume its because the char in the reduction is not moving so there is an acumulation of char from the oxidation zone that has no where it can go so it just reduces and reduces and fusing together causing this restriction.
I dont have the grate actuator motor running yet but yeah manual mode its made a huge difference. I can tell it was choking out before because now my mixer valve much more open. So a manual shaker at the grate must be standard at the very minimum.

Congrats on your first test run Darrell , a couple of things that made it easier for me was to move your mixer valve closer to the carb that was adjustments are instant also saves you bending round to see what your doing while spinning the engine up maybe even move the ammo filter can close to the engine so just a short length of pipe between filter and engine .
I also noticed you trying to light the flare almost straight away while your lighting port was open , again if it was me i would once alight close off that port and only let the air in through the nozzle, if that was old charcoal in your gasifier it will take a few mins to light where as brand new fresh charcoal will light almost within 20 seconds .
good video well done .

Recieved the wheel barrow today. Yeah Cody is right that thing is handy. It comes with this rock hauler thing its pretty cool and then it can convert into a hand cart. Yeah this is one of those buys you dont regret making. And with the flip out lift plate its like it was designed for a screen. They should make a screen attachement for it. We are not the only ones that need this and it works great for this.

Yeah Ill soon be working on it again, now that warmer weather is finally here and I have room in the shop. I need to get it on its back side with our overhead crane supporting the firewall. I can then cut out the old floor boards and weld in the new one.

Look at that bad boy!! LOL Yeah so going to have to make a revision so that the restriction plate can be removed for running on pure charcoal; while retaining the leg mounts. So Im going to make brackets that bolt to the lower flange at this level and they stay with the unit when you remove the upper section. No biggy and I knew this was going to be an issue.
But I think it will make much better power on charcoal with the restriction plate removed and then the clinkers wont be an issue. You will have to service the unit every once in while to get any acumulation of those things out. Either flip it on its lid and dump em or drop the grate.
I need to tighten up the grate as well. Its just a we bit too passive but would rather it be passive than clog up. So almost got it right but not quite.
