The Western Michigan University pilot coater can be viewed by its individual pieces in this diagram allowing for a better understanding of our coating services.
Roll size limit 72" (1820 mm) diameter and/or 8,000 lbs (3630 kg)
On machine, use with or without coater
Default set-up two-nip hot-soft, one-nip steel-to-steel, or both Four hot-soft nips are also available
Nip pressure to 2500 PLI (438 kN/m) using hot-soft and to 1500 PLI (263 kN/m) using steel-to-steel
Temperature ambient to 480F (250C)
Roll heating by hot oil internally and induction externally
Variations in temperature require 3掳F/minute to cool or heat steel roll.
To translate K眉sters calender set up to a specific mill calender condition, provide mill roll diameter, durometer, load, temperature, speed, and width. Conversion factors may require running calender separately from coater if speed to match to mill calendering conditions is slower than nominal coating speed.
Water and steam to add moisture into the sheet before the calender.
Measures moisture and basis weight.
