Annual Processing Capacity 1 Million Tons of Lump Ore Drying System (Anhui, China)

The Yunnan-Guizhou-Sichuan region is the core area of phosphorus mineral resources in China. For a long time, yellow phosphorus enterprises have been facing difficulties in processing low-grade phosphorus ores: the fine ore powder after beneficiation has a high moisture content (generally > 15%), is highly viscous and has strong heat sensitivity. Traditional drying equipment has low efficiency, high energy consumption, is prone to blockage, and fails to meet environmental protection standards, resulting in high production costs and restricting the profit margins of enterprises. To address this issue, our company has specially developed an energy-saving rotary dryer for phosphorus ore fines. With the core advantages of rich ore opening, cost reduction and efficiency improvement, and environmental protection compliance, this dryer helps yellow phosphorus enterprises achieve production upgrades!

Project Highlights:Precise temperature control + multi-level material lifting technology: Utilizing an intelligent temperature control system to ensure that the drying temperature remains stable within an appropriate range. Combined with the patented material lifting plate design, the phosphorus concentrate powder is heated evenly, with moisture reduced to ≤ 6%. This effectively prevents caking, blockage, over-burning, significantly improving the purity and fluidity of the concentrate powder, and meeting the high-grade raw material requirements for yellow phosphorus smelting.

2. Cost reduction and efficiency improvement

The combined hot air circulation system, combined with high-temperature resistant insulation layers, achieves a heat utilization rate of over 85%. Compared to traditional equipment, it reduces coal/gas consumption by 30%, and saves over one million yuan in fuel costs annually.

Intelligent operation and maintenance, halving of labor costs: The PLC automated control system can monitor temperature, rotational speed and air volume in real time. It supports one-click start and stop, as well as fault warning, reducing the need for manual intervention and lowering the difficulty of operation and maintenance.

The processing capacity of a single unit can reach 20 to 200 tons per hour. The drying efficiency is 30% higher than that of traditional equipment, helping enterprises expand production capacity and seize market opportunities.

3. Meet environmental standards, worry-free green production

Ultra-low dust emission: Equipped with a dual purification system of cyclone dust removal and bag dust removal, the emission concentration is less than 20mg/m³, which is far below the environmental protection standards. This helps enterprises pass the environmental assessment.

Exhaust gas heat recovery: An optional heat recovery module can be equipped to reuse the heat energy from the exhaust gas in the pre-drying process, achieving both energy conservation and emission reduction benefits.

4. Robust equipment capabilities, specially designed for phosphorus ore concentrate powder production

Anti-sticking design: The cylinder body is equipped with multiple levels of material-discharging plates and chains, which completely resolves the problem of phosphorus concentrate powder adhering to the walls, and ensures continuous operation without material blockages.

Corrosion-resistant structure: Key components are made of materials that are resistant to high temperatures and corrosion. They can withstand acid and alkali corrosion and are suitable for the high-humidity environment in Yunnan, Guizhou and Sichuan. The service life of the equipment is extended to over 10 years.

5. Strong adaptability

It supports various heat sources such as yellow phosphorus exhaust gas, natural gas, biomass, and steam, meeting the needs of enterprises of different scales. Customized installation can also be carried out in mountainous areas.
