Guys I found this site while looking for forklift info. I entered Allis Chalmers. They have something called Ball Mill and Sag Mill. I have no idea what they are. But it says they have 3000 HP? Dont tell Shameless, he'll have one of those dang 3000 HP motors on his dang old machine, world global warming will be over. Heck he'll have the equator covered in 6' of snow.

everyone has heard of a grain mill where you grind grain... A ball mill is a TYPE of mill used to grind coal at a power plant.. You have a BIG BOWL like a soup bowl but 6 - 10 ft in diameter. You put in a dozen "balls" that look like steel bowling balls... You rotate the bowl with a motor and the balls roll around inside.. You dump crushed coal into the bowl that is 1-2-3 inches in diameter.. The balls crush the coal into powder. This all happens inside a box with a blower fan on top causing a vacuum.. The "coal dust" gets sucked out the top as more coal is added to the bowl.. Constant feed and extraction.. You can run several tons per hour thru them.. ------------- Like them all, but love the "B"s. |

| Had mills as that at the Power Company dirt burners, actually used Barrels of misc diameter steel balls all rolling in the coal to beat it into powder, that would be air blown thru ducting into the furnaces. |

They also used ball mills to grind precious metal ore. The balls could be as big as a grape fruit and small as a quarter. I hauled them out of KC to south Mo for the mines down there. The large ones were heavy as the dickens. Leon |

So, then I take it the coal dust is highly flammable? ------------- I tried to follow the science, but it was not there. I then followed the money, and that’s where I found the science. |

YES... a "coal mill" is a little different than the above movies.. The coal is ground into a very fine powder. The atmosphere inside the mill has to be maintained so it is out of the Explosive range.. There is a big exhauster fan that SUCKS the dust out of the mill and forces it thru tubes into the blast furnace ............ at a power plant....... Everything is normally computer controlled these days.. Cuts down on the explosions. ------------- Like them all, but love the "B"s. |

The coal dust is blown into boiler and the amount controls the heat output of steam to run turbine for generation . The result is also no buildup of unburned coal and just a coal s-lag is the result along with fly ash which is saved to use as a additive to cement in making concrete. (posalone) the s-lag is separated and graded as roofing shingle particles and as blasting materials for sand blasting media . ------------- Life lesson: If you’re being chased by a lion, you’re on a horse, to the left of you is a giraffe and on the right is a unicorn, what do you do?
