Bald Ed I totally agree with you regarding the downtime as I said before the operation needs to be geared to the slowest item which is the chipper and then sufficient trailers to keep the operation constant. Did you notice the downtime of the chipper between grab loading again a feed system similar to a combine would improve production rates.
-
Buzz I realise what market it is intended for which is why Kesla market it for bioenergy, precisely the market we are talking about for utilising brash.
-
Obviously Kesla spend a great deal of money not listening to people Click on bioenergy kesla 4560c container http://www.kesla.com/videos/index.php?.Kansio=bioenergy&play=ok I cannot see how anybody could make this bit of kit have a reasonable output.
-
I am not blinkered just because I am looking for a better alternative to what those in "the know" have been putting forward as they openly admit the present way of brash baling is not economic for brash usage on a commercial basis. I cannot see dragging brash to the roadside to be any better as the cost of the machinery makes it uneconomic. Maybe its time to learn from the french http://www.eliatis.com/en/chaptrack.htm
-
Buzz The advantage I have is that I am also the CHP operator therefore I do not play by the normal rules
-
Brasher Quite clear to me. Quote direct from the BEIS guidance notes. Grants will not be provided for the following (the list is not exhaustive) Standard items of equipment routinely used for purposes other than bio energy production. eg chainsaws, felling machines.forklifts, JCB's standard transport lorries etc.
-
Brasher If you read the rules of the BEIS scheme you will see that all general plant and machinery costs are specifically excluded from the grant scheme.We secured grant for a wood pelleting plant and a woodchip drying plant.
-
But surely that involves double handling. loading onto the forwarder and then offloading again into the chipper. In the time it takes to load the forwarder you could have chipped the brash
-
Buzz But how do you make the brash dense enough on the forwarder to make it worth your while extracting without the use of a baler.
-
Coming from a farming background a silage machine is very similar to a woodchipper in that it is the slowest operation and the number of trailers required to support the machines continuous operation is dependent on the distance to the silage pit and the time it takes to unload. The same logic can be applied to the chipper. With regards the trailer, modifying the existing forwarding trailer would mean that a temporary top could sit on top of the IBC's attached to the existing grapple arm for ease of lifting up to remove the IBC's. Buzz It is because of the uneconomic nature of these balers that I am looking at alternative ways of extracting brash out of the forest using standard forestry equipment. Whilst I accept the extraction of roundwood to roadside for future chipping I cannot see how you can do the same for brash purely in terms of damage caused to the forest floor.

Does anybody know if plgloaders are still trading. I have tried to phone but no response on any of the phone options
-
This is the alternative approach I referred to earlier but how many chippers could you buy for the price of this machine and you still have the problem of Green brash as opposed to letting it die back for 2 months and then chipping it.
-
I never said a bulker was 20 cubic mtrs just an assumption for the size of a truck to give a practical comparison of IBC's to fill it as each IBC is approx 1 cu mtr. Why will filling a trailer be any different to filling 6 IBC's on a trailer.
-
Handfeeding you must be joking. 3 tonne tracked excavator with grapple into hopefully chipper which started this thread and our standard logging trailer modified to carry 6 IBC's at a time filled like a silage trailer
-
Filling of IBC's will be just like a silage trailer. Fill over the top of the containers and by the time you get to roadside the chip will settle into the containers. If truck carries 20 cubic mtrs then have 25 IBC's ready for loading on roadside. A good loader should load in less than 30 mins based on time needed to load a lorry load of potatoes.
-
Output depends on resources but you could go OTT like a farm silage operation with output dependent on the speed of the chipper. In reality we would want to keep the bulk tipper working to full capacity which obviously is dependent on haulage distance. As for trailers I think you will need bulkers as the material can be difficult to extract out of a walking floor.
-
We intend using the forwarder with IBC containers for extraction of woodchip from the forest to the main road then using a pallet rotation fork on a loader tip direct into artics for onward transportation. Similar technology used for handling potato boxes out of a muddy field.
-
The reason for the lightweight chipper is so that we can get into the woods with lightweight equipment and do less damage by chipping at the point of brash rather then dragging the brash out in bundles and then chipping.
-
Arran Woodfuels Depends on how you produce your woodfuel and the sort of woodchip burner. Soil contamination is not good for equipment or ash content which is why we prefer to extract without brash mats.
-
I am looking for a small woodfuel chipper that will handle brash to provide woodchip fuel of a grade suitable for a CHP plant. The Heizohack HM 4-300 seems suitable but the price on earborist is £14495 and direct from the same dealer is quoted at £17895. Can anybody advise of an alternative as I believe the dealer is taking the Michael. Is it possible to import direct and cut out the middleman.

Business wise I would have a word with your local Business Link. At the moment their seems to be more incentives by the government to reduce the number of unemployed so getting money for a business start up is becoming easier.

Converting chippings into fire bricks?
renewablejohn replied to hesslemount's topic in Firewood forum
Pelleting is not easy even with the right equipment you cannot guarantee the output. Its more akin to baking a cake. Start with the same ingredients and sometimes the pellets are good and other times you will get rubbish. Making briquettes is much more predictable but I would stick to a piston type as the screw type have a poor reputation for reliability. -
Farmers lung used to be a real problem before the days of air conditioned cabs now you have to remind workers to put a mask on when working in dusty conditions and I would include handling woodchips in this category. It should be automatic ear defenders for noise, face mask for dust and glasses to protect your precious eyes.

Deerman You may have overlooked the best woodchip boiler on the market. If you go back to the farm2000 link and look at the Refo woodchip boiler from Denmark. It is fully automatic like a gas or oil boiler so long as there is woodchip in the tank. It can automatically regulate itself down to 10% of maximum output and will increase in 10% increments depending on heat demand. Woodchip ash is non existent maybe 1 ashpan per month. It is not cheap but then it is the Rolls Royce of woodchip boilers. It will also burn other biomass fuels and grain and they will test your fuel to see whether the boiler is compatible to your fuel.

Video of the shear in action the excavator in the clip looks less than 3 tonne. [ame]http://vids.myspace.com/index.cfm?fuseaction=vids.individual&videoid=33354291[/ame]
