Phosphogypsum, a "by-product" of the phosphorus chemical industry, has an annual emission exceeding hundreds of millions of tons. Its stockpiling not only occupies vast land resources but also risks causing soil and water pollution, becoming a "persistent problem" hindering the green development of phosphorus chemical enterprises. With the advancement of the "dual carbon" goals and the tightening of environmental policies, the resource utilization of phosphogypsum is extremely urgent. In this transformation of turning solid waste into "treasure", the disc granulator independently developed by Henan Zhengzhou Mining Machinery Co., Ltd. (referred to as "Zhengzhou Mining Machinery"), with its core advantages of high efficiency, stability, and energy saving, has become "key equipment" in the phosphogypsum granulation industry, providing robust support for enterprises to establish a complete resource utilization chain.
1. Strong Technical Strength as Support
Since its establishment, Zhengzhou Mining Machinery has consistently focused on the research, development, and upgrading of equipment for the mining, chemical, and building materials sectors, accumulating over 20 years of practical experience, particularly in granulation technology. Addressing the characteristics of phosphogypsum such as "high moisture content, strong viscosity, and irregular particles," and problems like "low pelletization rate, high energy consumption, and easy clogging" in traditional granulation equipment, Zhengzhou Mining Machinery formed a dedicated R&D team. Through material property analysis, equipment structure optimization, and process parameter debugging, after hundreds of tests, they finally launched a high-efficiency and energy-saving disc granulator customized for phosphogypsum granulation, successfully breaking through the industry's technical bottlenecks.
2. Professional Design for Complex Working Conditions
High Pelletization Rate + Excellent Particle Size: By optimizing the disc inclination angle, rotation speed, and side height design, combined with a special feeding device, the pelletization rate for phosphogypsum remains stable above 90%, with particle diameter uniformly controlled between 2-8mm. This meets the requirements for subsequent deep processing like drying and calcining, avoiding product quality fluctuations caused by uneven particle size.
Anti-Adhesion/Clogging + Easy Maintenance:The disc liner uses special wear-resistant and anti-corrosion materials, with surface treatment specifically for the strong adhesion of phosphogypsum, effectively reducing material buildup on the walls. Simultaneously, the equipment structure is designed simply, allowing key components to be quickly disassembled and replaced, significantly reducing enterprise operation and maintenance costs.
3. Energy Saving and Environmental Protection, Reducing Operating Costs
Low Energy Consumption + Wide Adaptability: Through an intelligent frequency control system, the operating status can be adjusted in real-time based on parameters like phosphogypsum moisture content and particle size, reducing unit product energy consumption by 15%-20% compared to traditional equipment. Furthermore, the equipment can be flexibly adapted to different resource utilization pathways for phosphogypsum, such as producing gypsum boards, gypsum mortar, and roadbed materials, meeting the diversified production needs of enterprises.
4. Professional Service, Comprehensive Support
Henan Zhengzhou Mining Machinery Co., Ltd. not only provides high-quality equipment but also offers customers comprehensive professional services. From equipment selection, installation, and commissioning to later maintenance and technical training, the company has professional teams providing one-stop solutions. Regardless of any issues encountered during use, customers can receive timely responses and solutions from the company's professional technical personnel, ensuring a worry-free experience. The single-drum dryer from Henan Zhengzhou Mining Machinery Co., Ltd. is leading the phosphogypsum concentrate processing industry into a new stage of development characterized by high efficiency, quality, and environmental protection.
