INTRODUCTION

Alumina Calcination Line

The alumina calcination line is a specialized high-temperature calcination system designed for producing high-purity alpha-alumina (Al₂O₃). This production line utilizes a rotary kiln calcination process, where aluminum hydroxide or alumina is calcined at high temperatures ranging from 1200°C to 1500°C to convert it into stable alpha-alumina. The produced alpha-alumina is widely used in fields such as refractory materials, ceramics, electronic substrates, and abrasive materials. The production process is intelligent, environmentally friendly, and energy-efficient, ensuring high product purity, uniform particle size, and stable activity.

FEATURES

Precise Temperature Control, Stable Product Quality

An intelligent temperature control system accurately manages the temperature curve, ensuring uniform alumina particle size, reducing impurities, and enhancing product consistency.

Eco-Friendly and Energy-Efficient Design, Reducing Energy Consumption

Equipped with waste gas recovery and waste heat utilization systems, it minimizes energy consumption and carbon emissions, complying with green production standards.

Adaptable to Various Process Requirements

Capable of producing ceramic-grade, refractory-grade, and electronic-grade alumina to meet the needs of different industries.

Fully Automated Control, Reducing Labor Costs

The intelligent DCS control system enables real-time monitoring and      automatic adjustment of the calcination process, reducing manual intervention and improving production efficiency.

Complete Industrial Chain Support, Broad Market Prospects

Paired with a large water-cooled batch ceramic ball mill, it can produce alpha-alumina micro-powder below 4 microns, widely used in high-end material manufacturing. With continuously growing market demand, it offers excellent investment returns.
