Keywords：Gu Xin Single-Layer Ore Particle Color Sorter (Suitable for Both Dry and Wet Processes)

The Guxin Single‑Stage Ore Color Sorter (dual‑mode, dry and wet) is a versatile, cost‑effective, multi‑functional ore‑sorting machine designed for mines of all sizes, ore processing plants, and sand‑and‑gravel aggregate facilities. It is engineered to handle both dry and wet feed, offering broad applicability, low capital investment, simple installation, and hassle‑free operation. The unit can be integrated into dry‑process production lines or used downstream after water‑washing and dewatering in wet‑process operations. By replacing manual sorting and outdated, rudimentary sorting equipment, it meets the basic sorting needs of entry‑level users while accommodating the flexible, multi‑condition production requirements of medium‑sized mines. As such, it stands as a high‑value, mainstream standard model for mineral processing in mining operations.

I. Core Application Scenarios

● Dry separation application scenarios: In water-scarce regions and environmentally constrained mining areas, fully dry‑process ore production lines perform particle‑level impurity removal, waste‑stone separation, and whitening/purification. After crushing quartz, feldspar, fluorite, and calcite, dry‑particle classification and color sorting are carried out. For sand and gravel aggregates, pebbles, and crushed stone, sorting is performed to separate foreign colors, impurities, and weathered material. Pre‑sorting of coarse particles in the feed stream reduces the load on downstream equipment.   
● Applications of wet separation: At the downstream end of the ore washing line, slightly moist material after dewatering is directly fed into color sorting; washed quartz sand, washed feldspar, and washed fluorite undergo purification to remove impurities. In the wet‑process mineral processing workshop, materials with trace surface moisture—without obvious pooling—are sorted under these conditions. During the rainy season, when mine‑site materials are relatively damp, no drying is required, and they can be directly fed into the processing equipment.   
● Operating environment requirements:   
Dry separation: Material moisture content ≤ 3%; suitable for both indoor mine facilities and enclosed outdoor material sheds at ambient temperature.   
Wet separation: The material surface is slightly damp, with no visible free water; moisture content ≤ 8%. The housing features a moisture-resistant sealed design, offering corrosion protection and condensation prevention.   
Temperature adaptation: -10°C to +45°C, with relative humidity ≤90% and no condensation; suitable for long-term continuous operation in dusty and humid environments.

III. Types of Ore That Can Be Separated

Non-metallic minerals: Quartz, orthoclase, albite, fluorite, calcite, dolomite, barite, talc, gypsum, wollastonite, limestone, pebbles, granite, magnesite, pebbles, perlite, and others.

Metallic ores: Metallic mineral particles, including hematite, limonite, copper oxide ore, manganese ore, tungsten ore, spodumene, molybdenum ore, and others, are separated from waste rock, gangue, and low-grade impurities.

Other materials: Industrial pellets, construction debris, color‑separated recycled aggregates, glass, brick and concrete, etc.

IV. Particle Size Range for Sorting

General standard sorting range: 0.5 mm to 50 mm; optimal stable sorting range: 10 mm to 30 mm; customizable extensions: fine particles can be sorted down to 0.3 mm, and oversized chunks can be customized up to 80 mm; suitable for all particle sizes, from fine sand to large ore blocks, and compatible with both dry and wet operating conditions—no grain-size restrictions.

V. Sorting and Recognition Dimensions

● High-definition full-color CCD visual recognition: Ultra-high-resolution line-scan camera, precisely capturing subtle differences in material color, whiteness, color deviation, and grayscale.   
● Texture + Shape Intelligent Recognition: Distinguish between ore veining, crystal forms, irregularly shaped inclusions, weathered stone, and embedded impurity particles.   
● Multi-light adaptive fill lighting: Dual dry/wet light source adjustment; automatic calibration of surface reflections on wet materials to prevent false selections caused by moisture-induced glare.   
● AI Intelligent Self-Learning Algorithm: It comes preloaded with multiple standard ore formulations, supports customizable material models, allows one-click switching between dry and wet feed modes, and automatically adapts to varying moisture levels and the specific characteristics of different ore types.   
● Full-field, dead-zone-free scanning: Single-layer, uniform-speed flat‑bed conveying ensures that materials are neither stacked nor obstructed, with highly consistent recognition performance in both dry and wet conditions.

VI. Core Competitive Advantages

● Wet and dry use: The Guxin single‑stage model features a native design that supports both dry and wet processing, requiring no machine modifications or additional attachments. It enables seamless switching between dry and slightly moist materials, making it suitable for diverse applications such as mining operations during the rainy season, wash‑plant lines, and dry‑process lines.   
● Wide compatibility with mineral types: It handles over a hundred types of non-metallic and metallic ores, with a wide particle-size range, enabling a single unit to meet the sorting requirements of multiple production lines.   
● Airframe Corrosion Protection: The unit features a sealed design that protects against dust, moisture, and condensation; the frame is coated with an anti-corrosion finish, ensuring resistance to rust in humid environments and stable electrical performance, making it ideal for long-term use in wash-down workshops.   
● High cost-performance ratio: The aircraft model features a simple, well‑proven design and is priced far below that of double‑deck or imported models. It occupies a small footprint, requires no foundation or civil engineering for installation, and can begin production immediately upon arrival on site.   
● Low failure rate: The single-layer mechanical design features fewer components and long‑lasting wear‑resistant conveyor parts; its intelligent touch‑control interface is easy to learn with minimal training, and it offers low after‑sales maintenance costs.

VII. The Tangible Value Delivered to Customers

● Reducing labor costs: It fully replaces manual sorting, with a single machine capable of substituting for 30–50 workers, ensuring consistent year-round production and addressing the challenges of labor shortages and high error rates in manual sorting.   
● Enhancing Ore Grade: It effectively removes waste rock, yellow ore, black ore, and low-grade gangue, significantly enhancing the whiteness and purity of the final product, allowing for a 10%–25% price premium per ton for ores of the same grade.   
● Flexible adaptation to operating conditions: There’s no need to purchase separate dry and wet separators; one machine serves both purposes, reducing equipment costs and saving floor space.   
● Increase the resource recovery rate: Precision sorting reduces the loss of valuable ore, lowers the carry‑over ratio, and minimizes recoverable material in the tailings, enabling higher concentrate yields from the same feed grade and directly boosting mine profitability.   
● Meets environmental protection requirements: Dry separation produces zero wastewater and meets environmental standards; wet separation is compatible with water‑washing production lines, allowing materials to be processed directly without drying or sun‑drying during the rainy season, thus ensuring continuous operation.   
● Short payback period: Equipment investment is moderate, with energy savings and reduced O&M costs; typically, the initial capital outlay can be recouped within 6 to 11 months. The equipment boasts a long service life, ensuring stable, long-term profitability.
