Brash Chip Ratio.

[Qvatrees]

So popular opinion is somewhere between 5:1 and 8:1

 

I got loads more to work out but I think it's worth a look at making chip more valuable. Logs often make up an income in a arb business so why not try it with the chip?? I do Need to get some actual financial figures and see how it pans out tho

I don't know your situation, but if you have a chipper and store the brush, then chip it later with your own chipper (which you had all the time) you're mad!

Depends on what u chipping. I find that 3 bulk loads of coni makes about 1 load chipped and about 5 to 6 loads of oak, fruit wood, hawthorn etc make 1 load chipped

Was just wondering about storing brash then chipping it up after a few months when it's dry and lost its green. Hopefully reducing its moisture content for biomass. Any thoughts??

 

This was the idea behind brash baling, search fiberpac, basically make a long compact sausage of brash and cut it into 3metre by 0.7 diameter cylinders, forward these and transport them with conventional roundwood gear. Stack them outside the power station and chip them as and when needed.

 

In 2000 the machine only managed 80 1/2 tonne green bundles a day and with a capital cost of £250k it was uneconomic.

I do have a chipper but it's a 10year old 5" camon bought last year when I decided to turn back to arb. Nowt wrong with it but it will need replacing as soon as funds allow (and I don't do finance) so tbh it's not a huge deal towing brash from a to b instead. It's not like I've got a million quid financing a chipper to not use it

It's all about handling. You pick up a branch, maybe trim it, place it on the trailer, then you pick it up again to stack it, then you pick it up again to chip it. That's a minimum of three times. If you chip it on site you've touched it once.

It just not economic.

[Qvatrees]

I know !!!! 3 times handling vs 1 time no brainier but I'm thinking on it. It's an enigma isn't it lol. I just really want to make my chip piles profitable and it's gotta be better than burning coal

It's how some of the big yank company's role, tree team go out and stack brash at roadside and the grab wagon go's round and clears up after several teams at the end of the day then tips in the yard then something like a bandit beast comes in when full and deals with the lot in 1 go but all the handling in hydraulic and big.

Nothing worse than trying to pull a pile of mashed up brash apart then try feeding lots of little stuff into a chipper with out a feed conveyer is dangerous which then produces poor quality chip even through something with either twig brokers in or a screen so only producing power station grade stuff so low value and not worth it.

Chip the brash your little chipper will handle then keep all strate stuff over say 4" in 2m lengths that could be crane fed into say a hired in hiziohack once dry so producing good g30 chip and a possible return of £15 m 2 + if a local use for it.
