Steel Belt Tension Adjustment: Practical Handbook

Steel belt tension is one of the core parameters in roller press production. Excessive tension accelerates belt fatigue and tensioner wear, while insufficient tension causes slippage, tracking problems, and uneven product thickness. Mastering proper tension adjustment is essential for every sintered stone factory technician.

1. Basic Tension Principles

Roller press steel belt tension is typically measured in Newtons (N) or converted to percentages via tension sensors. For the SACMI PCR+ 2000, the nip zone rated tension is approximately 1,500-2,000N. The HLT HLT 1800 typically operates in the 1,800-2,200N range.

2. Five Steps for Tension Adjustment

• Confirm Baseline — Consult equipment manuals for the machine's recommended tension range
• Start Measurement — Read tension sensor values at normal operating speed
• Identify Deviation — Adjustment is needed when tension deviation exceeds ±10%
• Fine-Tune Spring or Hydraulic — Adjust no more than 5% of rated value per step, wait 30 seconds for stabilization before reading
• Record and Archive — Log pre- and post-adjustment values in equipment records

3. Common Issues and Solutions

4. Relationship Between Tension and Product Thickness

Every 10% increase in steel belt tension increases board compression rate by approximately 1.5-2%. During stable production, it is recommended to control tension fluctuations within ±5% to ensure product thickness CPK ≥1.33 quality standards.
