Zhicheng polyurethane sieve nets & a mining equipment co., ltd. in kunming: working hand in hand to create a new chapter in the mining industry

Zhicheng Polyurethane Sieve Nets and a certain mining equipment company in Kunming have been collaborating closely. Based on the operating characteristics and screening requirements of different mining machinery, they custom-design suitable sieve nets for core equipment such as jaw crushers, cone crushers, and vibrating screens. At the beginning of the project, the two sides formed a joint technical team and went deep into the mine frontline to conduct several months of research and analysis on ore characteristics and equipment operating conditions. According to the collected data, Zhicheng's R & D personnel accurately calculated the optimal aperture, tension, material thickness, and other parameters required for sieve nets at different stages.

For example, when providing vibrating screens for a large open-pit copper mine, considering that the copper ore has high hardness, uneven particle size distribution, and contains certain sticky minerals, the joint team, after repeated tests, finally decided to adopt a double-layered Zhicheng polyurethane sieve net. The outer sieve net features a high-strength, large-aperture design, responsible for intercepting large pieces of waste rock and buffering the initial impact of the ore; the inner sieve net has a fine aperture range of 0.5 - 5 mm, accurately screening out fine-grained ores that meet the requirements of the flotation process. This adaptive modification enabled the ore processing capacity of a single production line to increase by 30% in the first month, and the overall operating efficiency of the equipment soared.

In the actual production environment, Zhicheng Polyurethane Sieve Nets have demonstrated astonishing durability. The special molecular structure of the polyurethane material can effectively cushion the impact kinetic energy of the ore and greatly reduce wear. According to the monitoring data from multiple project sites of [the name of the mining equipment company], compared with traditional metal sieve nets, the service life of Zhicheng sieve nets has been extended by at least 40%, and in some working conditions, it can even reach more than twice as long.

This achievement benefits from the close cooperation between the two sides in product quality control. Zhicheng Company has introduced advanced production processes and adopted multi-layer co-extrusion technology to ensure that the polyurethane sieve nets have uniform physical properties from the surface to the inner layer. Meanwhile, [the name of the mining equipment company] provides real-time feedback during the operation of the equipment to assist in optimizing the sieve net structure design. For example, after discovering that the edges of the sieve nets were prone to tearing under certain high-impact working conditions, the two sides jointly developed a reinforced edging process, seamlessly integrating the metal frame with the polyurethane sieve net to further enhance the overall strength of the sieve net. This means that mining enterprises have significantly reduced the frequency of sieve net replacement and equipment downtime. Previously, it was necessary to shut down the equipment for 2 - 3 days per month to replace the sieve nets, but now it can be extended to once every 3 - 4 months. Not only has a large amount of manpower been saved for sieve net disassembly, installation, and maintenance, but also the production continuity has been significantly enhanced, and the comprehensive operation and maintenance costs have been reduced by approximately 35%.

Zhicheng Polyurethane Sieve Nets, with their high-precision screening technology, have brought a qualitative leap in the comprehensive utilization of ore resources. In the gold ore beneficiation process, the two sides cooperated to optimize the sieve net configuration. By precisely adjusting the sieve net apertures, they were able to nearly perfectly separate the gold grains from the gangue in the ore. The technical experts of Zhicheng Company and the beneficiation engineers of [the name of the mining equipment company] worked closely together. Based on the characteristics of the gold ore grade distribution, a three-stage screening strategy was adopted.

Firstly, large-aperture sieve nets were used to remove large pieces of waste rock. Then, medium-aperture sieve nets were used to preliminarily enrich the gold grains. Finally, small-aperture, high-precision sieve nets were used for fine screening, which increased the grade of gold concentrate from about 15% to 20% and improved the recovery rate by 8 percentage points.

In the beneficiation scenarios of lead-zinc ores, iron ores, and other multiple ore types, equally remarkable results have been achieved. The precise screening ensures the uniformity of the ore quality entering the subsequent beneficiation processes, effectively avoiding impurity interference, enabling flotation, magnetic separation, and other processes to be more targeted, significantly improving the quality of concentrate output, helping mining enterprises to extract greater economic benefits from limited resources and enhancing their market competitiveness significantly.
