The "Nano Active Zinc Oxide Combined Calcination Process" developed by Changzhou Haomai Drying Co., Ltd. fully utilizes calcination exhaust gas, simplifying and shortening the process flow while being suitable for large-scale industrial continuous production. It is a practical equipment technology that reduces production costs and improves economic efficiency.
Introduction to Zinc Oxide Drying and Calcination:
Currently, the main types of zinc oxide produced include active zinc oxide, high-purity zinc oxide, and nano zinc oxide. The dynamic zinc oxide drying and calcination process equipment researched and designed by our company represents advanced process equipment technology.
Introduction to Zinc Oxide Drying and Calcination Products
The traditional production methods for producing zinc oxide from zinc carbonate primarily involve two approaches: one using a vertical kiln, and the other using a rotary kiln. The zinc oxide produced through these methods has low activity, high energy consumption, and causes severe environmental and material pollution and waste. By adopting our company's dynamic drying and calcination process equipment, high-activity, high-purity zinc oxide can be produced. The zinc oxide flash drying and calcination furnace offers advantages such as energy efficiency, no environmental pollution, high recovery efficiency, a small footprint, and a high degree of automation.
Working Principle of Zinc Oxide Drying and Calcination:
The exhaust gas generated from calcining materials in a dynamic calciner enters the Sted dryer. A feeder sends filter cake-like zinc carbonate with a moisture content of 30–50% into the dryer, where it is dispersed and dried to form powdered zinc carbonate. This powdered zinc carbonate then enters the dynamic calciner, where hot air produced by burning coal, natural gas, or coal gas is introduced. The hot air mixes with the zinc carbonate in the calciner for heat transfer. Heated by hot air at 400–1000°C, the zinc carbonate rapidly decomposes into zinc oxide within seconds. The decomposed zinc oxide is collected by a collector and stored in a silo.
Performance characteristics of zinc oxide drying and calcination:
1. The decomposition temperature is uniform and rapid, enabling the production of high-activity, high-purity zinc oxide, with activity >80 and purity >99.
2. Filter cake-like zinc carbonate is used to produce powdered zinc oxide in a single system.
3. The heat consumption for production is 150–200×10⁴ kcal/ton.
4. Environmentally friendly, compact footprint, easy maintenance and operation, and highly automated.
5. Recovery rate > 99%
Technical Specifications for Zinc Oxide Drying and Calcination:
Within the series of machine models, the single-unit zinc oxide production capacity is 1,000, 2,000, 3,000, and 5,000 tons per year.
