Yunnan, Guizhou, and Sichuan are the core production areas of phosphate resources in my country. Yellow phosphorus enterprises have long faced the problem of low-grade phosphate ore treatment: the concentrate powder after beneficiation has high moisture content (generally >15%), high viscosity, and strong heat sensitivity. Traditional drying equipment has low efficiency, high energy consumption, easy blockage, and substandard environmental protection, resulting in high production costs and restricting corporate profit margins. In response to this pain point, ZK has developed an energy-saving rotary dryer specifically for phosphate concentrate. With the core advantages of enriching ore, reducing costs, increasing efficiency, and meeting environmental standards, it helps yellow phosphorus enterprises achieve production upgrades!

Project highlights:

1. Improve the quality of rich ores and increase the added value of concentrates

Precise temperature control + multi-stage lifting technology: The intelligent temperature control system is used to ensure that the drying temperature is stable in the appropriate range. Combined with the patented lifting plate design, the phosphorus concentrate is heated evenly, and the moisture content is reduced to ≤6%, effectively avoiding agglomeration, blockage, and 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. Reduce costs and increase efficiency

The composite hot air circulation system, with a high-temperature resistant insulation layer, has a heat utilization rate of more than 85%, reducing coal/gas consumption by 30% compared with traditional equipment, and saving more than one million yuan in fuel costs annually.

Intelligent operation and maintenance, labor costs are halved: The PLC automatic control system monitors temperature, speed, and air volume in real time, starts and stops with one button, and provides fault warnings, reducing manual intervention and the difficulty of operation and maintenance.

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

3. Environmental protection meets standards, worry-free green production

Ultra-low dust emission: equipped with cyclone dust removal + bag dust removal dual purification system, emission concentration <20mg/m³, far below the national environmental protection standard, helping enterprises pass environmental impact assessment.

Waste gas waste heat recovery: optional waste heat recovery module, waste gas heat energy is reused in the pre-drying process, energy saving and emission reduction double benefits.

4. Hardcore strength of the equipment, specially designed for phosphate ore concentrate

Anti-sticking design: a multi-stage lifting plate + chain is used in the cylinder body to completely solve the problem of phosphorus concentrate sticking to the wall and ensure continuous operation without blockage.

Corrosion-resistant structure: key components are made of high-temperature and corrosion-resistant materials, acid and alkali corrosion-resistant, and are adapted to the high-humidity environment of Yunnan, Guizhou, and Sichuan, and the equipment life is extended to more than 10 years.

5. Strong adaptability

Supports multiple heat sources such as yellow phosphorus tail gas, natural gas, biomass, steam, etc., to meet the needs of enterprises of different sizes, and can also be customized for mountain sites.
