Application Field
Working Principle
Advantages
I. Highly Efficient Transmission System
K Series Gearbox with Cemented Teeth and Direct Connection
- Cemented teeth, high load capacity, service life 3-5 times longer than soft-surface teeth
- The K series gearbox features high transmission efficiency (≥95%), ensuring energy saving and reduced consumption
- Direct connection design without belt transmission reduces energy loss and number of failure points
- High transmission accuracy, smooth operation, low noise level
- Simple maintenance, no frequent belt tension adjustment required
II. Super Durable Wear-Resistant Protection
Full polyurethane coating of the impeller
- Polyurethane wear resistance is 5-10 times higher than ordinary steel
- Corrosion resistance, adaptation to various water environments
- Good elasticity, reduces material crushing, protects the shape of finished sand particles
- Reduces noise during operation, improves working conditions
- Easy to replace, low maintenance costs, extends overall equipment service life
III. Comprehensive Advantages
✓ High Efficiency Design with two spirals significantly increases productivity
✓ High Reliability Heavy-duty design, high-quality key components, low failure rate
✓ Low Energy Consumption Highly efficient transmission system, significant energy-saving effect
✓ Long Service Life Gearbox with cemented teeth + polyurethane protection, long service life
✓ Simple Maintenance Direct connection design simplifies maintenance, quick replacement of polyurethane impeller
✓ High Product Quality High degree of cleaning, low clay content in finished sand, good particle shape
IV. Economic Efficiency
- Short equipment investment payback period
- Low operating costs (low energy consumption + low maintenance)
- Minimal downtime, high productivity
- High adaptability, ability to process various complex materials
Summary This heavy-duty twin-spiral sand washer, thanks to three key technologies — a powerful dual-motor drive system, a highly efficient and reliable transmission with a gearbox featuring cemented teeth and direct connection, and ultra-wear-resistant polyurethane protection — achieves the perfect combination of high efficiency, high reliability, long service life, and low costs, making it the ideal choice for large sand and gravel production lines.
Working Principle
1. Raw material immersion stage: the material is evenly fed into the washing tank through the feeding device to effectively soften and preliminarily separate soil and impurities on the surface of the sand during full immersion of the flow, creating favorable conditions for subsequent cleaning operations.
2. Mixing and cleaning stage: the spiral blade rotates at a certain speed, pushing the material in the cleaning bath to continuously roll, rub, and twist to ensure the removal of surface attachments.
3. Dehydration enhancement stage: the cleaned pure material steadily rises along the inclined tank by spiral blades; during the ascent, natural dehydration is performed through gravitational effect and sieve filtration, significantly reducing the water content in the material.
4. Drainage classification stage: wastewater is discharged through a scientifically designed drainage system; fine sand is returned to the cleaning process after treatment by an efficient recovery device, realizing the recycling of water resources and fine sand resources and improving economic efficiency.

Successful Cases
A large sand and gravel plant in Guangdong Province implemented our double-spiral sand washer, and the project was a complete success. This equipment is equipped with an advanced K series reducer with direct connection and carburized teeth, and the surface of the spirals is fully covered with polyurethane protection. The process from installation and adjustment to commissioning went without delays. The equipment demonstrated excellent results: smooth and reliable operation, high productivity, excellent quality of the finished sand — high purity, low moisture content, precise granulometric composition meeting national standards, which earned high praise and unanimous recognition from industry experts and clients.
