Acid Roasting Rotary Kiln

Product Specification

Feature

Sealing System: Combined dynamic/static ring seal with leakage ≤ ±500 Pa, or flexible packing seal to minimize air ingress. The effective sealing structure reduces moisture entry, preventing concentrated sulfuric acid from forming dilute acid, greatly reducing corrosion and extending shell service life. Kiln Shell: Made of acid-resistant material with high machining precision and minimal runout, ensuring reliable sealing and stable operation. Internal Structure: A spiral crushing device breaks up agglomerated and wall-adhered material. Multiple staggered rows of lifter plates agitate the material, prevent sliding friction damage to the shell, and improve heating uniformity. The special lifter plate angle design minimizes dust generation. Outer Jacket: Segmented construction with a special insulation structure prevents insulation wool from being blown off and disrupting production.
