Endothermic Processes | Hazen Research

Roasting processes use elevated temperature and controlled furnace atmospheres to effect desired chemical reactions in the furnace charge; roasting reactions may be either endothermic or exothermic. Although many furnace technologies exist, current industrial practice favors the rotary kiln and the fluidized-bed reactor for these applications.

Rotary kiln - Wikipedia

The mass of a typical 6 x 60 m kiln, including refractories and feed, is around 1100 tonnes, and would be carried on three tyres and sets of rollers, spaced along the length of the kiln. The longest kilns may have 8 sets of rollers, while very short kilns may have only two. Kilns usually rotate at 0.5 to 2 rpm, but sometimes as fast as 5 rpm.
