Cleaning
Removal of contaminants with minimal fiber loss

To minimize fiber loss, the rejects have to be processed in subsequent cleaner stages. In Voith's cleaner systems, in most cases two or three cleaner stages are required but no more than four stages.

InduraHiClean

Reliable separation of abrasive contaminants
With InduraHiClean, the separation starts in the headpiece. In order to break up existing flocks and prevent the agglomeration of fibers into new flocks, the incoming suspension is put into a vortex rotation with a high flow velocity. Without flocks blocking the way, the contaminants can be separated easily and reliably.

The BlueLine product range from Voith comprises modern machines and products for stock preparation that are characterized above all through the efficient use of energy and other raw materials and by gentle treatment of the fibers.
BlueLine Advantages
Reduced Fiber Loss
Lower Maintenance Cost
InduraPro

Separation efficiency for most stringent requirements
In the InduraPro system, two cleaners in the first stage operate with a continuous reject flow. The reject is sent via a sedimentation tank to discharge heavy containments and a booster pump into the second stage. Here, the fibers are separated from the reject and fed back into the process. Due to the small diameter of the second stage, even particles like small stones or sand can be separated, and the separation efficiency is increased significantly.

HiClean HCL5-l with EcoMizer

Maximum effectiveness and the least fiber loss
With stock consistencies of up to 3%, HiClean HCL5-I achieves the highest separation effectiveness thanks to its smooth inner surfaces and flow-optimized head piece. Cones made of plastic or wear-resistant ceramic flexibly adapt to the concentration of contaminants that are present.
Due to the high concentration of contaminants in the reject, fiber loss is low. In addition, the EcoMizer dilution and continuous overflow ensure obstruction-free and low-pulsation operation in all stages, even with the highest stock consistencies.
HiClean HCL5-I is for multi-stage fine cleaning of specific heavy contaminants from pulp suspensions in the stock preparation and approach flow systems.
Your benefits with HiClean HCL5-l
- Highest cleaning efficiency at high consistency
- Low fiber content in rejects by using EcoMizer technology
- Low stage factor and low flow at high consistency
HiClean HCL5-C with LightPlus

Combination cleaner for removal of specific lightweight contaminants
Your benefits with HiClean HCL5-C
- Low specific energy demand, as no full-stream lightweight treatment is necessary and less cleaners are required
- Reduced investment costs, as your existing equipment can be reused and investments in new equipment are minimized
Lightweight cleaner LT3

Reliable separation of lightweight contaminants
The lightweight cleaner LT3 is used in stock preparation and in the approach flow system to remove specific light contaminants from the suspension. It is also used for post-cleaning of the Combicleaner light reject and gas reduction.
Your benefits with Lightweight cleaner LT3
- No wax bleeding in final product
- Reduced Styrofoam content
- Reduced air content
