We had 2- 8 gauge industrial shotguns. They shot a quarter pound of lead. It was not uncommon to go through 4 or 5 cases at a time.(250 to a case) One shooting one loading,you could shoot out a lot of lead. If the chemistry was not exactly right it would form rings in the kiln which was 12 foot in dia. and 390 feet long,we had 3 kilns. The rings had to be shot out to allow the product to free fall as the kiln turned. I have seen balls in the kiln that formed in the back and were at least 8 foot in dia. We had to bust them up before they dropped in the cooler. Sometimes it seemed like we shot 2 or3 times a shift and sometimes we went weeks with out shooting. Our kilns were cement kilns,the lime was made into cement. The temp was different at certain parts of the kiln,over 3000 degrees,in the middle,about 1200 where it dropped in the cooler. The exhaust temps were lowered by spray water to as low as 400 degrees.
So, does this mean that the resulting cement is contaminated with lead pellets?
FWIW, my brother used to (and maybe still does) sprinkle lime in his outhouse to help keep down the smell and flies. I don't know whether it turns excrement to concrete, and I'm not interested in delving into it further.
