High Density Cleaner

High Density Cleaner

TT HDC.
Engineered to work both with virgin pulp and recycled paper, the Toscotec High Density Cleaner TT HDC is designed to reliably remove heavier than fiber contaminants, suspended in consistencies up to 6%, directly after the pulper. This will clean the stock and protect the machines downstream in the process (i.e. screens, refiners and deflakers). 

The inlet head geometry has been optimized to have high turbulence to break up existing flocks and prevent the formation of new flocks. The contaminants separation is then easily assured with minimal fiber losses by the centrifugal forces created as the pulp rotates inside the cleaner. The cone top part is made in stainless steel to have a long life, while the cone bottom part can be manufactured (for virgin pulp applications) in a transparent composite that resists wear but allows the internal vortex to be seen during operation. For heavier contaminated pulps, a stainless steel cone (with optional ceramic lining) can be used to maximize the cone life. Additionally, the heavy rejects trap is designed and automatically controlled to minimize fiber losses. It also has a sight glass to allow the process to be seen during operation. 

If installed as a first stage cleaner of a two stage system, it can be designed to have a continuous reject flow. If applied as a single stage or second stage cleaner, it is equipped with a contaminate trap that can be set as needed to automatically discharge the rejects and thoroughly flush the chamber with clean water.

The Toscotec High Density Cleaner TT HDC comes complete with a robust installation stand and all the valves necessary to operate and accurately regulate the water flow.  When used in a two-stage cleaning system, the Toscotec High Density Cleaner TT HDC can remove even small particles like small stones and sand.

All these features are achieved without a spinning rotor, which makes the Toscotec High Density Cleaner TT HDC a very easy to operate and quick to maintain essential unit. 

In addition, in case production is increased, the number of new parts required is minimal.
