GELEN screw classifiers are used for washing and dewatering sand. It is an inclined conveyor which is composed of a tank in which the sand is washed and a spiral shaft which transports the washed sand up the incline to the chute during which the dewatering happens. GELEN has both the one spiral and the two spiral designs with different length selections suitable for different output needs.

GELEN Compact Sand Plants produce low- moisture, saleable sand products with hydrocyclones and high-frequency linear motion dewatering screens that remove clay, silt, and slime using centrifugal force. Rubber- lined pumps and modular polyurethane screen decks ensure durability and easy maintenance. With capacities from 100 to 300 tons per hour, GELEN plants are ideal for industrial sand production, quarry fines optimization, and high- quality asphalt and concrete sand. Options include painted, galvanized, stainless steel, or high-performance polymer coatings. For large-scale operations, GELEN offers ultra- fines recovery, thickeners, and water treatment systems up to 4,000 short tons per hour.

GELEN Screw Classifiers, such as the HY Series, are primarily used for washing and dewatering sand. They are ideal for applications in mining, aggregates, and construction, where clean, dewatered sand is required for concrete production or other uses.
These classifiers are also effective in separating fine particles from water, making them suitable for environmental remediation and water treatment processes.
The spiral shaft in GELEN Screw Classifiers is designed to transport washed sand up an incline while simultaneously dewatering it. The rotation of the spiral creates a gentle lifting action, allowing water to drain away from the sand.
This design ensures efficient dewatering and produces clean, dry sand ready for use. The adjustable speed of the spiral shaft allows operators to optimize the process for different material types and output requirements.
The two-spiral design in GELEN Screw Classifiers offers higher capacity and improved efficiency compared to single-spiral models. It allows for greater throughput and more effective dewatering, making it ideal for large-scale operations.
The dual spirals work in tandem to handle larger volumes of material, ensuring consistent performance and reducing processing time. This design is particularly beneficial for high-output applications in mining and aggregates.
To ensure optimal performance and longevity of GELEN Screw Classifiers, regular maintenance is essential. Key practices include inspecting and replacing worn spiral blades, checking the condition of the tank and chute, and ensuring proper lubrication of the spiral shaft.
Operators should also monitor the alignment and tension of the drive system and check for any signs of wear or damage. By following a consistent maintenance schedule, you can minimize downtime, reduce repair costs, and maintain high dewatering efficiency.
GELEN Sand Processing Plants are designed for industrial sand production, quarry fines optimization, and high-quality asphalt and concrete sand production. They are also suitable for large-scale operations requiring ultra-fines recovery, thickeners, and water treatment systems.
Hydrocyclones use centrifugal force to remove clay, silt, and slime from sand, while high-frequency linear motion dewatering screens ensure the sand is low in moisture and ready for sale. This combination provides efficient sand processing and high-quality output.
GELEN Sand Processing Plants offer capacities ranging from 100 to 300 tons per hour. For larger operations, GELEN provides solutions with capacities up to 4,000 short tons per hour, including ultra-fines recovery and water treatment systems.
GELEN Sand Processing Plants are available with various material options, including painted, galvanized, stainless steel, or high-performance polymer coatings. These options ensure durability and adaptability to different operational environments.
