Dirt Check on Pulping Process

—Dirt Control by Measuring It with “Dirt Counter”—

Abstract

Dirt in the material of paper has been measured by checking dirt in the sample sheet that is made only for checking dirt.
By this way, the feedback timing is very late and also, it is very troublesome to make sample sheet, out of process.
Dirt Counter solved these problems by checking dirt directly in the slurry on the process. It is quite effective and convenient equipment, not only for DIP, but also for general KP.
