Metallurgical Rotary Kiln

Product Overview

The metallurgical rotary kiln, a cornerstone in the industry, leverages its high-temperature roasting capabilities to facilitate the physical and chemical transformation of metal ores. This accelerates the metal refining and material preparation processes.

The working process includes precise raw material feeding, dynamic roasting at high temperatures, and timely output of finished products. It spans the entire industry chain from steel, non-ferrous metals, and rare metals to non-metallic minerals, and plays a crucial role in waste treatment and resource recycling.

Structure and Components

Robust Kiln Body Construction

Welded from high-quality steel plates, featuring high-performance refractory bricks, and precision support and drive components for accurate rotation.

Multi-functional Burner Configuration

Located at the kiln head or tail, capable of using various fuels such as coal, natural gas, and heavy oil to generate high-temperature flames, meeting diverse roasting requirements.

Intelligent Drive System

Integrates motor, reducer, and gear systems to ensure stable kiln operation and provide continuous production power.

Sealed Facilities

Specially designed for the kiln head and tail to effectively isolate heat and material loss, maintaining a clean and safe production environment.

Efficient Cooling Solutions

Employs either a grate or rotary cooler to rapidly cool the finished material, creating favorable conditions for subsequent processing.

Working Principle

Precision Feeding Mechanism

Raw materials are introduced into the kiln through a customized feeding system, marking the beginning of their transformation process.

Dynamic Roasting Process

Driven by the kiln’s rotation, the materials tumble along the kiln wall, continuously exposed to high-temperature flames and hot gas flows. This exposure induces deep chemical and physical reactions, such as ore decomposition, oxidation, or reduction.

Efficient Discharge System

Once roasting is complete, the finished material is transferred through an optimized discharge port to either the next processing stage or directly into the cooling phase.
