Release Date:
2026-03-09
As the intelligent processing of non-metallic minerals continues to advance, the efficiency and quality of gypsum ore sorting directly determine the competitiveness of downstream high-value-added products in industries such as building materials, medical applications, and chemicals. As a mature piece of equipment in the field of color sorting for gypsum ore, the Guxin brand mineral color sorter has, through years of technological iteration and large-scale application validation, become the preferred solution for domestic gypsum mining companies seeking to upgrade their sorting processes and enhance product quality. With its stable and reliable intelligent sorting capabilities, it provides solid support for the industry in reducing costs, improving efficiency, and promoting green development.
As an important industrial raw material, the whiteness, purity, and impurity content of gypsum stone are the core indicators for assessing its quality. For a long time, the industry has relied on manual sorting, which is not only labor-intensive and costly but also limited by the human eye’s ability to discern subtle differences, making it difficult to precisely remove discolored impurities such as clay, limestone, and pyrite. This results in insufficient whiteness and significant grade variability in the finished product, failing to meet the demands of high-end markets. In response to the specific characteristics of gypsum stone and the operational conditions at mining sites, our company has spent years conducting research, development, and optimization to launch a dedicated mineral color sorter. This equipment is now widely deployed across major gypsum-producing regions nationwide and has become standard, replacing manual sorting and upgrading production processes. The color sorter is equipped with high-resolution linear CCD sensors and a multispectral optical system, integrated with our proprietary AI deep-learning algorithms to create a highly precise identification system. It can rapidly detect even the slightest color and texture differences between gypsum stone and impurities, enabling micron-level removal of minute contaminants. The machine features a dual-layer conveyor belt design with free-fall feeding, accommodating all particle sizes from 0.5 to 8 cm and supporting simultaneous sorting of mixed-size fractions without the need for prior grading, thereby greatly simplifying the process flow. Its millisecond-level high-frequency solenoid valves deliver precise air blasts with low carryover, minimizing loss of valuable product while maintaining sorting accuracy consistently above 99.5%. After color sorting, the whiteness of the gypsum stone is significantly enhanced, and impurity levels are reduced to industry-leading quality standards. As a mature, mass-produced model, the Guxin-brand gypsum stone color sorter excels in both stability and cost-effectiveness. The equipment features a sealed, dust- and water-proof design suitable for both dry and wet operations, coupled with an automatic self-cleaning dust-collection system that enables it to operate reliably in the humid, dusty environments typical of mining sites. It supports 24-hour continuous operation with low failure rates and simple maintenance. A single unit can replace dozens of workers, increasing sorting efficiency by more than 80% compared with traditional methods, while reducing overall energy consumption and simultaneously improving raw-material utilization and yield, delivering substantial economic benefits to mining enterprises. Thanks to its proven, reliable performance, this equipment has been widely adopted in key producing regions such as Ningxia, Hubei, and Shandong, earning a large base of long-term customers and an excellent reputation.
The company is a national high-tech enterprise with many years of deep expertise in the field of mineral color sorting, focusing on the R&D, manufacturing, and service of intelligent sorting equipment for non-metallic minerals. The Guxin brand mineral color sorter boasts exceptional versatility, capable of handling nearly 100 types of minerals, including gypsum, quartz, calcite, fluorite, and potassium feldspar. In particular, the gypsum-specific model has undergone extensive market validation over the years, demonstrating mature technology and stable performance. Leveraging proven technology, the Guxin mineral color sorter effectively addresses the key pain points in the gypsum sorting industry, driving the transformation of gypsum processing from traditional manual methods to intelligent, precision operations—aligning with the goals of green mine development and high-quality growth. Looking ahead, we will continue to optimize and upgrade our solutions, delivering even more reliable and efficient sorting systems to support the long-term development of gypsum mining enterprises and help the non-metallic minerals industry steadily advance toward new heights of intelligence and sustainability.
