Mill Hot Gas Requirement Articles

raw mill drying problem page 1 of 2,raw mill drying problem. we have a ball mill, the average moisture of the mix is ca 4-5 but during strong raining season it comes up to 8 hot gas coming from the kiln is not enough to dry the material, we have also installed a hot gas generator (hgg) to use in case of kiln shutdown..cage mill delumps and dries materials in one step,mar 15, 2005 standard cage mills can handle temperatures up to 300f. hot air (temperatures from 100f to 1200f) is introduced with the feed material and conveys de-lumped and dried material through the uptake duct of the cage mill. use the unit with hot gas stream from within plant for tremendous fuel savings..
