G50 wood chip, any good?

[briquette_seller]

If it was mine it would all be rejected as it has far to many long shards which creates problems with most auger feeds. What sort of chipper is it and does it have a G50 screen in the chipper.

 

Looks more like output from a shredder than a chipper.

 

Really?

 

That surprises me.

I used to put stuff at least 3 times bigger through an old grain auger with no problem.

 

I thought the whole idea of these chip burners were that they burnt a multitude of stock?

Seems crazy that they are so fussy.

Not fussy just designed for woodchip of a certain spec which does not include long shards. Big difference between a grain auger going at full chat and an auger turning one revolution every two minutes.

Ok.

 

Always learning.

 

Might look at trading it in then.

The other problem with shredded chip is bridging in the delivery/ holding system. That sort of chip would bridge across walking floor elements causing a cavern you could stand up in.( if you are crazy enough to do it )

I dont think it would be very far off whats going through my boiler at the moment, but in the bottom left picture you can see a fair few shards, which tend to travel along the auger , but pop out just before it goes through the wall into the boiler house forming a sort of birds nest at that point. Im sure that if I didnt clear it out before refilling, then eventually it would stop.

The chip looks like the blades were blunt, as you say the ragged ends give the heap a negative angle of repose, a cavern will form and does under a sweep arm too.

Yes I've seen this too as the auger trough enters the square tube.

 

I'm wondering if a vibrating conveyor with 50m holes would allow in size chip to drop through and shards to carry on off the end, for manual loading or rechipping.

I'm sure if you spoke to Dean on here, he would be able to get it set up to produce a better quality of chip, maybe smaller screens or better knife configuration.

If you do decide to sell it, please drop me a pm first..

Brand new knifes, so they were sharp.

There must be something else wrong then. Mind I've had a stand up row with a fitter who swore blind he had sent out a gm1928 with fresh discs and they produced chip like this, yet with genuinely sharp disks it produced a good sample. One of the things about modern chippers is that they continue to chip and load when blunt but it increases wear and tear.

 

Having said that there is no reason that chip will not feed given suitable equipment.

I have seen shards like yours from a Heizo when the cordwood went in sideways the teeth just chew great lumps off instead of making decent chips, having decent length material and keeping the lengths going in straight makes an amazing difference
