how to use less cement and burn less tires.

[scemmostu]

he says the steel in the tires adds to the steel content of the material- which is a cost savings. so there goes the rust theory.

@thegaysailors The EPA and most states will not allow a permit to exist to burn tires without some sort of recovery system in place.

A Lafarge plant manager told me that the balls that grind the cement to a powder are made of Chromium (which is a toxic heavy metal). Steel can't be used because it would impart a rust in the cement.

I hope there are filters to catch the mercury and other toxic pollutants from the burning of tires.

What a great video! You guys did a great job! I'm curious: Is the feed material entering the kiln 1600 F or C? At what Temp is the clinker formed? (max-normal ops temp for kiln?) What other heat source powers the kiln besides the tires? About the ball mill: is that a continuous feed ? I'm wondering what size diameter are the balls? If the balls fill 40%, to what total percent is the mill chamber filled? I really enjoy this video and want to thank you again for posting it!
