Modern continuous kiln in lime

Apr 23, 2020

The potential to install new modern PFR lime shaft kilns for product category 1 at low or stagnating market growth is still substantial because today the number of modern PFR lime shaft kilns is less than 800 This means that there are still high quantities of lime being produced with outdated kiln models
