Rotary kilns are used in various processing materials through high-temperature reactions. The cylindrical vessels rotate slowly on their axis, allowing materials to move through the kiln while being exposed to heat. Rotary kilns have applications in cement production, lime calcination, mineral processing, and waste incineration, among others. Here’s what you should know about rotary kilns and how to find rotary kiln expertise including for kiln thrust rollers.
Different Types of Rotary Kilns
Rotary kilns can be classified based on several criteria:
Length-to-Diameter Ratio
Short kilns have a ratio of less than 16 (dry kilns), while long kilns have a ratio of 30-40 (wet kilns). Spray kilns fall in between.
Feeding Method
Dry kilns process materials with low moisture content, while wet kilns handle materials with higher moisture, using either the inflow or injection method.
Cooling Method
Some kilns incorporate multiple cooling cylinders at the hot end (multi-cylinder cooler kilns), while others have separate cooling systems.
Kiln Type
Based on geometry, kilns can be straight barrel, cold end expanded, hot end expanded, firing zone expanded, or both ends expanded.
Transmission Type
Common types include girth gear-pinion drive and friction drive rotary kilns.
Heating Method
Most kilns are internally heated, but external heating is used for processing toxic or high-purity materials.
Function
Kilns are either used for material processing or waste incineration.
