7/23/2023 0 Comments Pressed fireplace 4kOn a basis for your self, base cost for a pellet assembly capable of compressing any type of wood is $4k for the mill ( chi com mfg) + apx $2k for a unit to reduce material to 4-6mm bits. The average tree service chipped material is a poor candidate due to foreign materials that would/could damage compression equipment same for a lot of the pallet companies or other wood working services. Switch grass requires large acreage competing with corn, cattails its a harvesting problem. Several large concerns are in production as we speak down south and out east, most of their production goes to EU.Ĭommon cattails have a very high lignin content and make an excellant stand alone base material, switch grass is another. Moisture content of base material must be closely regulated at about 8-12%. To exclude binding agent and only rely on lignin requires raising supply material to apx 190 degF. Got a fair amount of research time in this. Most common binding agent ( regardless of company hype) is corn starch. Real overall problem is that total cost of production on a small scale exceeds return revenue state side. which raise the operating cost to about the same as anything else or in some cases more. From sprayed sawdust to compressed pucks and nuggets( similar to the old coal self feeders of years gone by) Most have not succeeded to well due to regulations requiring certified boiler operators and the ever present EPA type regs. Continuous feed heating units have been installed and tried many times in various countries in EU. state side not the biggest market Europe is where 90% of all bio mass produced here is sold. *Perhaps* it could be automated and you could make firewood logs cheaper than the normal way, but without equipment costs and actually making some prototype pressed chip logs, I can't see how you could make any educated guesses on it, any big scale extrapolations.Ĭompressed wood log, on a scale that could produce for sale, start up cost from zip = about $100k ( very small production line), $60 k for a base compression unit, rest for pre and post processing. could you convince normal wood buyers to shell out the extra? OK, marketing, how many manufactured logs can you sell? Would it be competitive with normal cut and split firewood? Say it costs twice as much, but the logs are twice as good and nice and neat and uniform as regular split wood. A lot more than a regular drum chipper I guess, something that would do really large chunks. I have no idea what a decent tub grinder costs or the operating expenses with it. You get a heaping whole buncha chips fast though if ya got the branches and small trees to feed into the thing. I was using a 12" vermeer wood chipper here before it broke, that is my only experience with commercial sized chippers. I don't see a chip log reference, but sure seems doable.Īs to producing the chips as the total feedstock as opposed to using chips that are secondary to the primary wood product.no idea, never owned operated or even seen a tub grinder. It says the way they do it with sawdust is no paraffin, or with paraffin. If you can come up with a press from your splitter, just try it, see how they come out. As opposed to just waiting then having massive forest fires. I have never looked at a commercial operation for making the chip logs, nor the bio char, just read about the latter some as it seemed a good thing to do with the one billion dead pines out west from the pine beetle. If you can mash just chips together and make them stick as-is, so much the better. I have only seen those paper wrapped fireplace logs, they look like they have an added ingredient.
