New Type Coal‑Fired Vertical Lime Kiln – Automatic Operation
Product Spotlights
Product Introduction
The new‑generation coal‑fired vertical lime kiln adopts optimized internal structure and fully automatic control system, realizing stable calcination of quicklime with coal as fuel. It features low energy consumption, high lime activity degree, low over‑burning and under‑burning rate, simple site layout and small investment. The whole production process from raw material feeding, coal proportioning, air supply, calcination to finished lime discharging can be finished under automatic monitoring. This kiln is widely used in metallurgy, chemical industry, environmental desulfurization, building materials and other fields.
