Thanks & What about Grinders

This might form a useful substitute fuel for a power station, perhaps?

...or as a feedstock to a bioethanol plant? It's not unusual to use wood for tansportation purposes. After all, Casey_Jones did it!

biggest problem in grinding is nails that break the carbide teeth. A fair amount of ground wood might be used by mushroom growers, as they use cellulose manure and the mold eats wood.

OK, so once its ground then what?

Depending on fineness and yourlocation, wood pellets are a manufacturable product for such as you seem to be describing.

Bob - you don't say where you are and that is important because depending on what you decide to do you will be faced with the relevant legislation. I dont know about N. America but in Europe wood is easy enough to deal with and you can make wood pellets or indeed just chip it and sell it to someone for a soild fuel heating system - plenty being built right now with government grant funding. Chipboard is a bit of a problem because of the binders used in its manufacture - you would need to find out what the end user is prepared/allowed to take in that regard. I would suggest that for C&D you should think about a hammer mill rather than chippers or shredders because of the high breakage costs when hitting nails, bolts etc. They are expensive to buy and operate though.

Bob, you reflect my feelings towards CR4, right down to the knuckle head part - lots of helpful, intelligent people out there.

I work in the recycling industry, not on grinders, but know a lot about this stuff (Phd from HKU - Hard Knock University) and have many connections - Re: what works, what does not.

I Really Love this whole recycling industry - big machines, big noise, whats not to love?!

Not sure how the forum works, but would not want to plug any one grinder.

Low speed high torque seems to be a more popular choice lately. some people are pre-grinding the waste stream (concrete, rocks, rebar and all...) and then sorting it.

The sorting technology gets better all the time... trust me, I know that part.

there are so many choices. Identification of market should be foremost in your decision - what are you doing with the residue? Fuel? Mulch/Compost?

If you are in a single location, a non-mobile unit would be most economical - maybe even an old hogger from the pulp industry.

If you need to be mobile, or want to consider extra revenue (grinders are expensive) maybe a mobile unit would be best. You could "contract grind" for local municipalities, etc. to help offset the cost.

If your looking for biggest bang for the buck, and are a low volume processor, (not sure if 20-75 tph would support capital investment) you might want to consider finding a "contract grinder" in your area.

Personally I like the horizontal machines, and everyone seems happy with the units they own. Tub Grinders are much more exciting; with the potential to throw huge chunks of debris hundreds of feet... Man, that will keep you on your toes!

If your starting out, be careful of used stuff... you get what you pay for!

Hope this helps, You should post some pictures, so the CR4 family can see what this business is all about.

Good luck, Keep us posted on your venture!

First, I'd look to salvage values:
Look into sale of 'remainders` (>4' lumber an >1/4 sheet OSB & Plywd.) - Wood is pricey enough now that there may be a market among 'DIY`ers.

Then, minimum labor input:
Wood chips are commonly sold as mulch. - Check out local gardening suppliers as a market.

PLYWOOD AND PARTICLE BOARDS USE BONDING AGENTS THAT MAY BE HARMFUL TO THE ENVIRMENT. YOU MAY WANT TO CHECK THIS OUT BEFORE USING.
