What to Look for When Choosing a Rotary Kiln Manufacturer

Proven Rotary Kiln Design. Be sure to select a rotary kiln manufacturer with proven equipment. The difference between proven and unproven design may not be obvious at first, but there are things you can look for to help validate manufacturer claims. One aspect to look for is a service division; this usually means that the manufacturer’s equipment has been around long enough to require ...

Rotary Kiln Design: Sizing - FEECO International Inc.

In the FEECO design process, once we have engineered a rough design of the rotary kiln, we use several computer programs to help predict and model how the material will behave in the rotary kiln we have designed. We review the combined analyses, and if our design does not meet the appropriate criteria, we adjust accordingly. Conclusion. Rotary kilns

Ever since the first Ransome kiln (until recently) rotary kilns were turned by means of a single girth gear (known as the turning gear) surrounding the kiln. The early kilns turned very slowly, the girth gear meshing with a worm gear. Subsequently full-speed rotation of kilns in the range 0.5-1.5 rpm became standard, and the gear meshed with a pinion running at 10-20 rpm. The pinion shaft was ...
