Wet end

Valmet’s pulp drying technology is based on the experience gained in manufacturing and deliveries of more than 300 machines to customers worldwide.

These include the world’s widest pulp drying machine so far with a trim width of almost 11 meters and a record capacity of close to 5000 ADmt/d. The latest machine design allows for production rates per width meter of 500 ADmt/d and minimized energy consumption.

To meet our customers’ specific needs, Valmet’s wet end technology comprises both Fourdrinier type solutions and Gap technology with two-sided dewatering and wire pressing.

In both wet end alternatives, the first open draw takes place at a dry content exceeding 40%, which guarantees running reliability especially with short fiber pulp. The embedded automation solutions feature wet end web profile control systems for process optimization. This maximizes the runnability and pulp web quality of the pulp drying machine. And, it minimizes web breaks and MD basis weight variations while protecting the wires and headbox.
