As a major industrial solid waste from power plants, fly ash features mixed raw particles with a wide particle‑size range, resulting in limited direct utilization value. Mass stockpiling not only occupies land resources but also creates environmental pressure. Ultrafine classification serves as a key process to realize resource recovery and value‑added utilization of fly ash. The ITC‑Series Air Classifiers are specially developed for dry‑process ultrafine separation of fly ash, helping enterprises convert solid waste into high‑quality powder raw materials.

Supported by high‑speed classification wheels and a secondary‑air elution structure, the ITC‑Series Air Classifiers efficiently disperse agglomerated particles to achieve precise separation of coarse and fine fly ash. The finished product particle size can be flexibly adjusted within the range of 5‑150 μm. The produced ultrafine fly ash boasts narrow particle‑size distribution and high activity. It can be directly used as a mineral admixture for high‑performance concrete and filler for new‑type building materials, complying with production standards for Grade Ⅰ and Grade Ⅱ fly ash, and effectively improving the market value of end products. Equipped with wear‑resistant protection structures, the whole machine withstands erosion by hard fly‑ash particles, greatly reducing equipment wear and tear, and is suitable for high‑capacity continuous industrial production.

The complete ITC‑Series air classification production line operates under closed negative pressure and is fitted with a pulse dust‑removal device to prevent dust leakage. Equipped with an intelligent electric control system, it enables convenient parameter adjustment and delivers high classification efficiency with balanced capacity and energy consumption. It helps building‑material and new‑material enterprises cut costs and boost efficiency, responds to the trend of green and low‑carbon development, and provides reliable equipment solutions for the recycling of industrial solid waste.
