The Yunnan-Guizhou-Sichuan region is the core production area of phosphate rock resources in China. Yellow phosphorus enterprises in this area have long faced the challenge of processing low-grade phosphate rock. The moisture content of the concentrate powder after beneficiation is high (commonly >15%), it is highly viscous and thermosensitive. 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 pain point, Zhengkuang Machinery has developed a high-efficiency and energy-saving rotary dryer specifically for phosphate concentrate powder. With the core advantages of efficient extraction of high-quality ore, cost reduction, efficiency improvement, and compliance with environmental protection standards, it helps yellow phosphorus enterprises achieve production upgrades!
Enhancing the Quality of High-Quality Ore and Increasing the Added Value of Concentrate
Precise Temperature Control + Multi-Stage Material Lifting Technology: An intelligent temperature control system is adopted to ensure that the drying temperature remains in the optimal range. Combined with the patented design of material lifting plates, the phosphate concentrate powder is evenly heated, and the moisture content is reduced to ≤6%. This effectively prevents caking, blockage, and over-burning, significantly improving the purity and fluidity of the concentrate powder to meet the requirements of high-grade raw materials for yellow phosphorus smelting.
Cost Reduction and Efficiency Improvement
Unique Composite Hot Air Circulation System: Equipped with a high-temperature resistant thermal insulation layer, the heat utilization rate exceeds 85%, reducing coal/gas consumption by 30% compared to traditional equipment and saving over one million yuan in annual fuel costs.
Intelligent Operation and Maintenance, Halving Labor Costs: The PLC automated control system monitors temperature, rotation speed, and air volume in real-time. It features one-touch start/stop and fault warning functions, reducing manual intervention and the difficulty of operation and maintenance.
The processing capacity of a single unit can reach 20-200 tons per hour, with a 30% increase in drying efficiency compared to traditional equipment, helping enterprises expand production capacity and seize market opportunities.
Compliance with Environmental Protection Standards, Ensuring Worry-Free Green Production
Ultra-Low Dust Emissions: A dual purification system combining cyclone dust removal and bag dust removal is configured, with an emission concentration <20mg/m³, far lower than national environmental protection standards, assisting enterprises in passing environmental impact assessment reviews.
Exhaust Gas Waste Heat Recovery: A waste heat recovery module is optionally available, recycling the thermal energy of exhaust gas for pre-drying processes, achieving both energy conservation and emission reduction benefits.
The Equipment's Robust Strength, Tailored for Phosphate Concentrate Powder
Anti-Sticking Design: The cylinder is equipped with multi-stage material lifting plates and chains, completely solving the problem of phosphate concentrate powder sticking to the wall and ensuring continuous operation without blockage.
Corrosion-Resistant Structure: Key components are made of high-temperature and corrosion-resistant materials, resistant to acid and alkali corrosion, and suitable for the high-humidity environment in Yunnan-Guizhou-Sichuan. The service life of the equipment is extended to more than 10 years.
Strong Adaptability
Supports various heat sources such as yellow phosphorus tail gas, natural gas, biomass, and steam, meeting the needs of enterprises of different scales. Customized installation is also available for mountainous sites.
