DETERMINAITON OF WATER REMOVAL BY WET PRESSES

• The objective of this procedure is to provide guidelines for press testing under production conditions . The following procedures are most appropriate for straight through presses.
• The measurement of water removal by a press section is conducted for many reasons, including:
  • To determine average sheet moisture content throughout a press section.
  • To monitor the effect of changing pressing conditions such as press loading, felt design and age, roll crown, roll cover, sheet temperature, and furnish.
  • To develop cross machine profile information.
  • To compare data on pressing efficiency with other presses.
  • Calibration and/or verification of on-line moisture sensing and measuring instruments. Standardized test procedures permit comparison of moisture data from different presses.

It Provides information on:

• Sample equipment needed.
• Preliminary organization and data gathering.
• Position identification.
• Sampling sequences.
• Press test sampling with no doctored press rolls.
• Moisture measurement.

Who will benefit:

• Engineers.
• Maintenance Manager.
• Laboratory Personal.
• Analyst.
