• Lifting Lug: Included for safe handling during installation.

2. Technical Specifications and Performance

• Throughput Rates: Based on Portland cement bulk density of 1.13 t/m³; actual throughput depends on proper silo design and cone fluidisation to maintain constant, even material flow.
• Limitations: Throughput may not scale proportionally with all cement types; some may cause partial or total flushing (siphoning), affecting performance.
• Performance Charts: Throughput capacity varies with screw diameter (114 mm to 323 mm) and inclination angle (5° to 50°), showing decreased capacity at higher inclinations.

3. Design Features and Benefits

• Universal Inlet Spouts: Compatible with various silo designs for versatile material intake.
• Splined Shaft Design: Ensures robust mechanical connection and simplifies maintenance.
• Modular Construction: Simplifies transport, installation, and maintenance.
• Low Maintenance: Components engineered for minimal upkeep and extended service life.

4. Quality and Certification

• WAM® holds UNI EN 9001 - 2000 certification, demonstrating commitment to quality management and continuous improvement.
• Proven track record with over 200,000 units supplied globally over 40 years.
• Recognized for technical excellence and reliability in cement feeding applications.

5. Recommendations and Best Practices

• Ensure silo and cone fluidisation systems are properly designed and maintained to achieve specified throughput rates.
• Maintain constant and even material flow to avoid non-proportional throughput and flushing issues.
• Utilize modular components to facilitate logistics, installation, and maintenance.
• Perform regular inspections via standard hatches to ensure operational integrity and longevity.
