Quote from: Magicman on Yesterday at 07:24:30 AMI am assuming that they are taking manageable layers so after it is taken down to the level where the crusher is, will they begin another layer deeper. I suppose that I am wondering how deep your recoverable stone goes. Maybe to China?Yes, i have a extracting plan which was accepted from the mining ministry, so more or less i need to follow some rules and guide lines. One thing they are complaining is the first wall (the bottom hole, where the crusher is), is way too high and vertical so i need to cut another terrace. We will do all that but last year was very hectic and they needed to full fill orders. this year i will make more use of the D9 dozer (as it is payed from this firm and doesn't cost me a dime) and organize the quarry a little better. make more room, strip more overburden and make more terraces.

They used to take "dirty" chips and sawdust mixed which was a blessing for a small mill.The main problem is the mixing of dirty wood chips and sawdust. If we process them separately, we can obtain pellets of the highest quality. Chips with bark must first be crushed to the size of a broken match. When the raw material comes out of the dryer, it must be sifted to separate the sand. The ash content in raw materials is reduced from 3-4% to 0.5-0.7%. The ash content in fine screenings is 15-25%. The purified raw materials are re-crushed and processed into pellets. Here is a video where the difference in the separated contamination is noticeable even in color.
