Product Description

The Guxin marble‑specific color sorter is custom‑designed for marble sorting applications, employing intelligent algorithms to precisely distinguish between discolored material, impurities, and substandard pieces. It operates reliably in both dry and wet environments. The machine accommodates materials of various particle sizes, boasts a high degree of automation, and delivers exceptional sorting efficiency, helping stone‑processing enterprises enhance quality and productivity while optimizing the grade of raw‑material output. Guxin’s marble‑specific sorter is tailored for the entire marble industry chain, supporting diverse applications across the full spectrum—from quarrying to advanced downstream processing.

I. Product Applications

1. Primary sorting of raw ore at the mine: crushed raw ore particles ranging from 1 to 80 mm in size. Purpose: to remove discolored material, black spots, yellow veining, and interlayered rock, thereby increasing raw material purity and reducing losses during subsequent processing.  
2. Sorting scenario prior to slab processing: rough blocks and slab blanks before cutting. Purpose: Grade by color and grain pattern to ensure uniform color within each batch, thereby increasing the yield of high-end slabs.  
3. Premium stone material purification process: Used for producing small-sized aggregates (1–30 mm) for mosaics, handicrafts, and high-end decorative applications. Function: High-precision sorting to remove minute defects and foreign-colored inclusions, ensuring product appearance and value.  
4. Dual‑mode dry/wet crushing and sorting application: handling either wet‑washed material or dry‑crushed material. Function: ensures stable operation across all operating conditions, separates reject material from qualified product, and enhances recycling recovery rates.  
5. Reuse of scrap and edge‑cut material: Edge and fragment waste generated during cutting and grinding. Function: Sorting by color and grade, converting low‑value scrap into high‑quality raw materials such as mosaic tiles and crushed stone aggregates.  
6 High-end building materials and export‑order applications: engineered panels, countertop slabs, and export orders that demand stringent color‑difference control and purity standards. Function: replace manual quality inspection, establish digital standards, ensure batch-to-batch consistency, and reduce the risk of returns.

III. Technical Advantages

1. Image Processing System: Cutting-edge DSP and FPGA processing technologies, combined with color‑ and spatial‑based multi‑mode complex algorithms, deliver “color sorting + shape sorting” capabilities tailored to various materials. With freely configurable modes, you can select from tens of thousands of material types.  
2. Camera Acquisition System: Imported high-precision camera lenses ensure clear, accurate imaging; an imported high-precision 5,400-pixel high-speed linear full-color smart CCD is employed for high-definition recognition and rapid sorting.  
3. Self-priming nozzle: Equipped with a professional high-speed air valve, it delivers rapid actuation, low power consumption, and extended service life; reduces air consumption, achieves faster response, more precise impact, lower carry‑over ratio, and higher throughput; with a service life exceeding 10 billion cycles.  
4. Light Source System: LED optical design system, with multiple light source options to accommodate various materials; addresses issues such as high temperatures, significant power loss, and shortened lifespan that arise from prolonged LED operation; ensures long-lasting durability under stable temperature conditions.  
5. Feeding System: An advanced material-feeding detection system is employed to ensure uniform material flow.  
6. Crawler Conveyor: It employs a tracked conveyor system, delivering excellent color‑sorting performance and stable material handling, which effectively improves the carry‑over ratio and sorting purity while also significantly reducing material breakage during the color‑sorting process.  
7. Wide range of applications: Corresponding operating modes have been designed for different materials, enabling a single machine to perform color sorting on various types of materials.  
8. Operating System – Simple and Easy to Use: Touchscreen displays from professional manufacturers, an intuitive human–machine interface, a clear and easy-to-read operation menu, and simplified settings enable customers to quickly master the various functions of the color sorter.
