First of all, if you are going to buy coal like that, expect prices to be not so cheap because you are going to have to compete with China. Rumor has it that they keep buying all the coal on the ground, and I am told that is why coal prices are higher. The other thing is, if your idea is to buy someone elses raw coal and run it thru your own beaker or gravel machine, how much profit do you expect to make doing that? All the hard work of mining it and getting it out of the ground is already done. Running it thru a breaker is easy. You can't charge much just for that, and I really don't think that you are going to be able to buy raw coal from the miners cheap enough for you to jack up the price after cleaning, sorting and breaking it and still stay competitive with your prices. I just don't see how it would be worth your time. If you want to get into the coal business, get your own mining machines and get a permit. Then you could sell to China yourself!
