Sludge Dewatering Screw Press Unit (GNDL303)

The GNDL303 sludge dewatering screw press is a cost-effective, eco-friendly mechanical dewatering solution applicable to diverse types of sludge in municipal and industrial wastewater treatment. It adopts advanced screw extrusion technology to realize uninterrupted solid-liquid separation. During formal operation, the rotating screw propels sludge forward continuously. Along with the gradual change of internal cavity geometry, the sludge is subjected to progressive compression. The synergistic effect of increasing extrusion pressure and precise gaps between fixed and floating ring plates enables efficient water separation from sludge mass while fully intercepting solid particles. This innovative working principle realizes one-stop continuous sludge thickening and dewatering with minimal operational complexity.

To optimize dewatering efficiency, sludge is conditioned with polymeric flocculants before entering the screw press, which promotes dense and stable floc formation and facilitates internal water release from sludge structures. To match the overall operational requirements of the project, GN Separation equips this turnkey package with the self-developed GNSJY3000 chemical dosing unit, ensuring accurate, stable and automatic preparation and dosing of sludge conditioning agents.

Wastewater Flocculation Dosing Unit (GNSJY3000)

The GNSJY3000 dry powder chemical dosing system is a specialized automatic unit for polymer solution proportioning, maturation and storage. The entire equipment body is made of premium stainless steel for corrosion resistance and long service life, with a modular structural design that independently completes chemical proportioning, stirring, maturation and storage. In operation, dry polymer powder and water are accurately proportioned and fully mixed in the preparation module, followed by sufficient stirring to form a uniform preliminary solution. The solution is then transferred to the maturation zone for full curing to ensure stable flocculation activity. After maturation, the qualified polymer solution is stored in the dedicated tank and continuously and quantitatively delivered to the sludge conditioning unit via dosing pumps, maintaining consistent chemical concentration and stable sludge conditioning performance throughout the operation.

The integrated combination of GNDL303 screw press and GNSJY3000 dosing system forms a complete and systematic sludge dewatering solution. Equipped with a mature PLC automatic control system, the entire production process realizes intelligent management of core operating procedures, greatly reducing manual intervention, lowering labor costs and simplifying daily operation and equipment maintenance. Meanwhile, the compact integrated package design effectively saves floor space, simplifies cross-border transportation and on-site construction procedures. On-site installation only requires basic water, power and sludge pipeline connections, significantly improving project implementation efficiency.

Energy-saving and low-wear operation is another core advantage of the system. Different from traditional high-speed centrifugal dewatering equipment, the screw press runs at a low and stable rotation speed, which effectively cuts down overall energy consumption and reduces mechanical friction and wear, extending equipment service life while maintaining efficient and stable dewatering results. The separated filtrate can be recycled to the front-end wastewater treatment process or discharged up to standard, while the dewatered sludge with low moisture content can be continuously discharged for subsequent transportation, harmless disposal or resource utilization.

With all manufacturing processes and strict factory inspections fully completed, the integrated sludge dewatering package has entered the final shipment preparation stage for European delivery. GN Separation will provide full-process professional technical support for on-site installation, commissioning and trial operation to guarantee stable and standardized equipment operation for the client’s project.

GN Large Linear Vibrating Screen for Domestic Mining Company

GN Separation Equipment, a globally recognized expert in solid-liquid separation and intelligent screening system solutions, has recently completed the full-cycle manufacturing, strict multi-stage performance testing and formal delivery of its flagship GNLS3073 Large Linear Vibrating Screen for a leading domestic mining company. This customized heavy-duty screening unit will soon be officially deployed in the core mineral processing production line of the client, aiming to comprehensively improve the material screening and classification efficiency of the entire process, significantly enhance the long-term operational stability of the production line, and provide solid equipment support for the enterprise to achieve continuous, uninterrupted high-load operation under the extremely harsh, highly abrasive and high-impact working conditions unique to mining sites.

2026.08.05 Large linear vibrating screen

Different from the traditional circular or elliptical motion vibrating screens widely used in the early mining industry, the GN large linear vibrating screen adopts a mature and optimized pure linear motion design. During the full operation cycle, all materials on the screen deck move along a stable and uniform straight-line trajectory, which effectively avoids the problem of uneven material distribution and local accumulation on the screen surface that often occurs in non-linear motion screening equipment. The complete equipment system is composed of multiple core modules with independent intellectual property rights, including a heavy-duty imported vibration exciter with long maintenance cycle, an integrated high-rigidity screen box, a multi-stage composite vibration damping system assembled from high-elasticity rubber springs, a modular adjustable support structure and a high-efficiency energy-saving drive device. Unlike many screening products on the market that can only be installed in a fixed way, the GNLS3073 series supports both full horizontal installation and flexible layout with adjustable inclination angle within a certain range, which can be quickly adapted to different process links such as coarse ore pre-classification, concentrate dewatering, tailings desliming and dry stacking in mining production, providing extremely high application flexibility for various complex mining application scenarios.

In order to ensure that the equipment can maintain stable performance for a long time in the harsh mining environment full of high-hardness ore impact, high dust, high humidity and long-term continuous load, GN Separation Equipment has applied a large number of advanced structural design concepts and precision manufacturing technologies in the whole process from raw material selection to final assembly and testing. The side plates of the screen box are made of high-quality high-strength alloy steel plates that have undergone multiple times of flaw detection and tempering treatment, which have far better impact resistance and deformation resistance than ordinary carbon steel plates, and can still maintain the integrity of the structure after being subjected to frequent high-strength ore impact for a long time. More importantly, different from the traditional process that relies on a large number of welding to connect various components of the screen body, the main connection structure of the entire screen box adopts imported Huck rivet hydraulic assembly technology. This process completely avoids the hidden danger of structural cracking caused by welding residual stress in the long-term vibration process, and greatly improves the overall structural reliability and anti-fatigue life of the equipment.

2026.08.05 Mineral application vibrating screen

Before the official start of production, GN’s senior R&D engineering team, which has more than ten years of experience in the design of mining screening equipment, carried out a full range of finite element analysis (FEA) structural optimization for the customized GNLS3073 unit according to the specific working conditions and process parameters provided by the mining customer. The engineers simulated the stress distribution, vibration frequency and dynamic response of each key component under 24-hour continuous full-load operation, carefully adjusted the vibration parameters of the exciter and the mechanical structure size of the screen body, accurately avoided the resonance risk that may occur during long-term operation, effectively reduced the unnecessary vibration impact of the equipment on the foundation and core components, and further extended the overall service life of the complete machine on the premise of ensuring high screening efficiency.

The GNLS3073 delivered this time is also equipped with an independently optimized vibration beam structure. The supporting cross beam adopts a specially designed rectangular tube structure, which achieves ultra-high structural strength while controlling the self-weight of the equipment within a reasonable range, avoiding the common problem of excessive self-weight of the beam in similar products. All key load-bearing components such as the vibration beam have undergone professional secondary stress-relief heat treatment after welding, which eliminates the internal stress generated during the welding process to the greatest extent, ensuring that the equipment can still maintain extremely stable performance and excellent fatigue resistance even under the condition of non-stop continuous operation for several months.

This successful delivery is another important milestone for GN Separation Equipment in the field of large-scale high-reliability screening equipment for the global mining industry. After the equipment is put into operation, it will help the domestic mining customer significantly increase the screening efficiency of the production line, reduce the failure rate of the screening link by more than 30%, and effectively reduce the comprehensive operation and maintenance cost of the enterprise, creating solid and considerable economic benefits for the customer’s high-yield, low-carbon and intelligent transformation of mineral processing.
