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.
