Wire Remover-Unit

Valmet Wire Remover-Unit offers a cost-efficient, fully automatic solution for dewiring and destacking pulp bale units.

Pulp

Bleaching of chemical pulp

The key success factors in bleaching chemical pulp are effective mixing of bleaching chemicals into the pulp, well-defined retention times in bleaching reactors and barrier washing between bleaching stages. Barrier washing results in low chemical consumption, low effluent flows and the possibility to operate at zero fresh water consumption.

Bale quality system, BQS

Valmet, the global leader in pulp and paper lines, supplies the Bale quality system (BQS) as a supervisory tool designed to keep track of production data and quality parameters for bale handling. BQS is a unique system that tracks each individual bale, bale set and bale unit throughout the production line. The system uses absolute bale position tracking to ensure exceptional reliability of key data.

Fiber flash dryer

The Valmet Fiber Flash Dryer is a money saving alternative when you invest in a pulp drying line. A flash drying system for both mechanical and chemical pulp entails considerably lower investment than conventional sheet drying plants.

Valmet Headbox

One of the most important parts of a pulp drying machine is the headbox. The modern wet end features an advanced dilution controlled hydraulic headbox, which ensures an excellent web profile both in cross and machine directions.

Pulp

Creating additional value streams

Valmet has several solutions for closed circles at pulp mills and for using production side streams to create new value adding products.

OptiSizer Spray sizing

In surface sizing, the size is sprayed on nip rolls through a row of spraying nozzles. Then, the size is transferred to the web in the nip. You can control the amount of size accurately and fast, and there are no consumables due to contactless application, which leads into decreased downtime.

OptiFlo Layering Fourdrinier headbox

OptiFlo Layering Fourdrinier tackles the board makers’ challenges in combining lower basis weights, faster speeds and higher ash contents resulting from the increased use of recycled fiber. This provides excellent layer coverage, considerably lower residual variation in basis weight as well as an excellent formation.

New opportunities with Valmet sizing

The R&D work did not stop after the first OptiSizer Hard was started-up. It was seen as a good place to improve further. There have been a number of pilot trials and the results with a new application method and a new concept combining OptiSizer Hard and OptiCalender Metal Belt seem to be clear.
