Rotary Kiln: The Core of Industrial Calcination

A rotary kiln is a slowly rotating cylindrical furnace used for high-temperature processing of materials. It's the backbone of cement, metallurgy, chemical, and environmental industries.

How It Works

Material enters from the upper end, moves downward as the kiln rotates (1-4 rpm, 3-5% incline), and undergoes chemical or physical transformation at 1000-1600°C before discharge.

Simple in concept. Demanding in execution.

Key Components

• Kiln shell: Alloy steel plate with refractory lining

• Tyre & support rollers: Carry the rotating weight

• Drive system: Motor + gearbox + girth gear

• Seals: Prevent air leakage at both ends

• Burner & cooler: Heat source and product cooling

Our Manufacturing Capability

At CIC Heavy Machinery, we produce rotary kilns:

• Diameter: Φ1.6m ~ Φ6.0m
