Fresh branches with leaves (chipper type?)
Hello! I am new to this forum thanks for the valuable information.
We are looking for a wood chipper suitable for freshly pruned trees. Material consists of branches with many twigs and leaves. The machinery needs to be compact and efficient. What type of chipper would be appropriate for this process?
I have seen wood chips from a disc chipper and there were a lot of slivers in the final product. Not really pleased with the result, as I want it to be usable in domestic woodchip boilers.
Thanks!
EDIT: Also like to add that the maximum diameter of the larger branches is around 4"

Are you looking for a standalone shipper or one that operates off the rear pto on a tractor?
I've only used disc chippers and you're right about the slivers. There aren't many slivers in hardwoods but softwoods are another story. My guess is a drum chipper would do better but I can't say that with any authority.

Thank you for your prompt reply.
I don’t really mind if it gets power from a tractor or it has its own engine as long as I can efficiently get woodchip of uniform size.
In theory I thought that disk chippers should produce more uniformly sized chips than drum chippers. But from what I have seen (when chipping relatively small branches) the size is not really uniform.
I was thinking that maybe a hammer mill type of design could be the most appropriate for the kind of raw material I am planning to process but it is getting hard to obtain relevant information since most of the chippers in the market are designed for logs.
I would really appreciate it if I could get some feedback regarding this matter.
Thank you again

This style looks interesting. It claims "exceptionally uniform" chips that can be augered without further screening and continuously adjustable chips sizes from 1/4" to 1".

I had a promark 6" disk chipper. Not good for processing anything. Sold it. Hammermill is probably your best bet. Be careful of drum types --we call them "chuck and duck"s. A few years ago a loacl tree guy loaned his to a buddy. The buddy's 4-year-old got snagged on a branch being fed and well... The dad was basket case after that and so was the owner.

EW, why would a drum type be any worse than any other type with a hydraulic feed? The hydraulic feeds on my Bandit 12" disk chipper are relentless. Or are you talking about a drum type without hydraulic feed?
I've gotta say, after having hydraulic feed I wouldn't use anything else.

I never knew they had hammermill type chippers. Do you mean like a feed mill type hammermill with a screen under the hammers? That sounds like something that would be real loud and use up horsepower like it was free.
The power company sometimes dumps chips out back for us just to have a place to get rid of them. I'm sure it is a drum type with knives to slice the branches. The chips seem to be pretty uniform, we use them for tree mulch.

Psychro (where did that name come from?):
A wood chipper is not a paper punch. To maximize uniformity get one with a manual feed or an easily-adjustable roller-feeder, and ensure the material is fed in slowly and gradually.
If the specs are, say, a six-inch intake, that just means that size intake, not that it will chew a 6" log -- unless it's balsa wood.
You might look into renting one the first time. It's more work than you'd think feeding it, and maintaining it (which the owner does).

Kw, a drum type is basically the feed--except it can't be controlled since it's the business end. A disc has a feed usually two which does control the rate of what is being chipped. My 6" was crap and it was a commercial unit mounted on a trailer with a 10-yd self dumping chipper box. It would not pull in anything that was even a hair larger than the opening---like a y-branch. And yes it would chip a 6" log but was not fast. A drum could suck it in and chip it in a split second. But they take a lot of hp and are expensive.

| re: Fresh branches with leaves (chipper type?)
Thanks so much for all the information. I apologize for getting so long to answer. I am writing from Europe (Greece). This is the main reason I am not asking for a specific model but a type of machine, since this type of equipment is not that common in my area and getting hold of one, or even ordering is quite difficult. Most of the companies don’t even have a distributor in my country, so I will have to order from abroad.
If I understand it correctly, a chipper with some kind of controllable feed could be the best solution for my case. I recall the person chipping branches (using a disc chipper), without uniform result, telling me how fast he was able to process the raw material. Maybe that was the problem.
In case I want to chip 4” logs I should be looking for a higher specs machine. I also realize it’s a lot of hard, as well as a dangerous work, so I am thinking for an automatic feeder (maybe using a conveyor belt), but in this case I am afraid some amount of manual work will be needed too..
A drum chipper will be larger, more expensive, require more power to run and more dangerous at the same time. Does a comparable specification drum chipper have any more advantages, except the fact that it will probably work faster?
Finally I would like to ask if there is any other type of chipper that could work for chipping branches.
This is a great community with many solutions and ideas. I hope I can soon get this project going and post more news.
ps. psychro = cold (in greek). It comes from a few years ago, the time I was studying refrigeration and air conditioning using psychrometric charts
