Vortiscreen 3 Series

TT VS-3.
The Toscotec Vortiscreen TT VS-3 can be installed as the only coarse screen in converting broke lines or as the last tail screening stage for the treatment of the rejects coming from drilled Toscotec Superscreens in recycled paper processing lines.

The unit and the holes sizes are chosen according to the line concept and the contamination level of the pulp.
Screening consistency can range from 1% to 5% depending on application.
This machine characteristics allow it to perform an efficient screening with minimal fiber losses without breaking down impurities. The Toscotec Vortiscreen TT VS-3 is designed to work in batch mode and can be supplied with all the valves necessary to automatically manage the working and washing/discharge cycles from the DCS.

The stock is axially fed to the end of unit through the central feeding pipe. The impeller forces the accepted fibres through the filtering plate.

Its design prevents any stringing and allows the maximum dryness of the rejects.

In addition, the rotor shape ensures high deflaking effect even with cured wet strength broke. The contaminants are accumulated in the vat and are discharged together with the washing water and eventually sent to central reject de-watering equipment.

Its natural pumping effect means no pump is required to feed or discharge the TT VS-3.
In order to optimize the performance of the TT VS-3, it is possible to set the duration of each sequence phase on the DCS.

This unit is completely manufactured in stainless steel with a wear-protected rotor and wear stripes on the filtering plate. This makes the Toscotec Vortiscreen TT VS-3 highly resistant to wear and ensures a very long life.

The design of the Toscotec Vortiscreen TT VS-3 reflects the long term experience of Toscotec in recycled paper treatment and its ability to manufacture simple but effective equipment that is easy to maintain.

Cleaning and Screening Systems

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.

Superscreen

TT SS. The Toscotec Superscreen TT SS is a horizontal screen with basket and rotor designed to be installed as a coarse or fine screen in recycled paper stock preparation plants. It is optimal to treat stock up to a working consistency of 5%.

Vortiscreen 1 Series

TT VS-1. The Toscotec Vortiscreen TT VS-1 is used in recycled paper stock preparation plants mainly for the detrashing of the continuous TM Pulpers and as a dumping machine of high consistency batch pulpers.

Vortiscreen 3 Series

TT VS-3. The Toscotec Vortiscreen TT VS-3 can be installed as the only coarse screen in converting broke lines or as the last tail screening stage for the treatment of the rejects coming from drilled Toscotec Superscreens in recycled paper processing lines.

Turbo Separator

TT TMC. The Toscotec Turboseparator TT TMC is installed in recycled paper stock preparation lines as primary screen to treat the accept stream of the Toscotec Low Density Pulper.

Broke Pulper

TT MBP. The Toscotec Broke Pulper TT MBP is designed to be installed under machine both in tissue, paper and board applications.

Rotating Screen

TT RS. The Toscotec Rotating Screen TT RS is used in recycled paper stock preparation plants to de-water the coarse rejects coming from upstream cleaning equipment.

Ragger

TT RG. For the proper performance of a continuous pulper working with recycled paper (Toscotec Low Density Pulper), a cleaning unit such as the ragger TT RG is required to be installed.

Low Density Pulper

TT TM. Optimized to work with heavily contaminated recycled paper or with rewinder trims, the Toscotec Low Density Pulper TT TM is designed to perform an extremely efficient and low energy slushing in continuous mode and to remove rejects without breaking them.

Medium Density Pulper

TT VP. Suitable to work both with virgin pulp, broke, recycled paper and non-wood fibers, the Toscotec Medium Density pulper TT VP is designed to perform an extremely efficient and low energy slushing in discontinuous mode.

Turbo Separator

TT TMC. The Toscotec Turboseparator TT TMC is installed in recycled paper stock preparation lines as primary screen to treat the accept stream of the Toscotec Low Density Pulper.

Vortiscreen 3 Series

TT VS-3. The Toscotec Vortiscreen TT VS-3 can be installed as the only coarse screen in converting broke lines or as the last tail screening stage for the treatment of the rejects coming from drilled Toscotec Superscreens in recycled paper processing lines.

Thickening Screw

TT CA. The Toscotec Thickening Screw TT CA is an inclined screw thickener; it can be configured as a Single Unit or as Combined Units (up to 3 Units on a single stand and with only one feeding headbox) for higher capacity and reduced footprint.

Wire Washer

TT CW. The Toscotec Wire Washer TT CW is used to obtain an efficient removal of ashes, inks, glues, and fines by means of low consistency stock washing and consequent thickening.

Short Approach Flow System

TT SAF. Toscotec Short Approach Flow TT SAF, patented by Toscotec since 2012, allows every mill, new or existing one, to reduce energy consumptions and installation space, without compromises in terms of performances.

Vibrating Screen

TT V. The Toscotec Vibrating Screen TT V can be used as final stage for rejects de-watering after other screens such as vortiscreens, superscreens and pressure screens.

Pressure Screen

TT AFS. The Toscotec Pressure Screen TT AFS is designed to be installed in the approach flow system as final protection of the headbox.
