thanks catweazel, interesting thoughts and considerations. actually i meant really a biomass boiler, rather than pellet burner, but your points are still spot on. ive recently been looking at wood chip boilers, and i wondered what the difference was ( v biomass), perhaps they cover the issues you mention. also i still need to improve the grade, unfortunately on the m300, it looks like i need shims to move the blades and anvil (or counterblade as jobeau call it) closer together, so thats my next job

I will sort out the anvil then, and see what i can achieve... simple enough. thanks for the help.

thanks for such quick responses, good to hear that it sounds like i could be getting better chips out of it directly. I will check the gap of the anvil - I did not realise it was adjustable, probably because the manual is in Spanish, and my Spanish is not too hot at present. Will try to work it out/find a copy of the manual in English. Feed to fast.... okay, being a bit dumb here... isnt the feed controller by the throttle of the motor? i.e run fast, the drum is rotated quicker = faster feed, or is it not that simple? Im usually run the engine at around 2/3 throttle (its honda 13hp engine) and crank it up, if needed due to thicker branches. Slightly concerned if I slow it down, it will snag due to hardness of wood, as I assume a certain speed/power was needed for cutting. fyi, the almond branches are on average 2-5cm diameter on the main branch, but obviously i still have attached the rest of the 'pruning', so theres a fair amount of 5mm or so twigs attached still thanks again for the help

hi, Ive got a JoBeau M300H which im generally very happy with, and is serving me well, im using it to chip almond tree cuttings (so hardwood) but have a couple of questions I wonder if anyone can help me with... (not sure if its a specific to jo beau or not really) a) the output chips, are quite large (1-2cm), and it sometimes throws whole twigs through (i.e. unshredded), though only when small diameter (say 3mm ish) Ideally, id like to get these down to a smaller size, and with no twigs.... (so chips could be fed into a pellet burner) is it possible to adjust the chipper, or do i need to process with another machine? if so do you have any recommendations? b) I have new blades on the machine, but would like to get some spares... are there any recommendations? in particular to deal with almond wood given its so hard thanks for any thoughts and suggestions Mark
