Abstract

The MDDA(Modified Dynamic Drainage Analyzer) was developed to evaluate the drainage at hydrofoil table roll and low vacuum devices on fourdrinier paper machine MB-former. Comparison of the results was obtained using a computer simulation system based on Taylor's equation and filtration equation and by measuring the consistency profile in a paper machine presented an agreement within 10.7% This device can evaluate the dewatering pro-file on wire for various stock properties adjust dewatering devices on fourdrinier paper machine and control the dosage of retention aids for improving paper structural properties and runnability of papermachine.
