Frequently Asked Questions About Agitation Equipment
What is a chest agitator used for in paper mills?+
A chest agitator maintains uniform pulp consistency in storage chests, machine chests, and mixing tanks. Without agitation, pulp fibers settle and form lumps, causing inconsistent stock feed to the paper machine.
What types of agitators does Parason manufacture for paper mills?+
Parason manufactures two types: Hydro Turbulence Agitator (HTA) — CFD-optimized for large chests and towers (7.5–110 kW), and Vertical Agitator (PVAT) — top-mounted for smaller chests and tanks (5.5–75 kW).
What is the difference between a Hydro Turbulence Agitator and a Vertical Agitator?+
The HTA uses CFD-engineered blade geometry for controlled turbulent flow throughout the entire chest volume — ideal for large storage chests. The PVAT is top-mounted with an optimized impeller creating efficient downward circulation — suited for stock chests and process tanks.
Why is proper agitation important for paper machine operation?+
Insufficient agitation causes fiber settling, consistency variations, fiber lumps causing sheet defects, dead zones where stock stagnates, and inconsistent paper weight and formation. Stable agitation is essential for stable paper machine operation.
Where are agitators installed in a paper mill?+
Machine chests (before the headbox approach system), storage chests, mixing chests (where different furnish streams are blended), broke chests, and chemical mixing tanks.
