Roll covers for pulp drying

Long running periods with Valmet’s roll covers

Pulp drying machines are harsh chemical environments for roll covers. Reliable roll covers are needed to reach long running periods between planned shutdowns and to ensure long fabric lifetimes. Valmet’s roll covers are running and proving their performance each day in largest pulp dryers in the world.

The right, modern roll cover solution brings more benefits

Valmet has an excellent selection of rubber covers providing reliable and cost efficient operation. For cases in which traditional approach no longer provides optimal wear resistance, there are more modern materials, such as composite or polyurethane covers available for the pulp drying process. Compared to customary rubber compounds, these modern roll cover materials bring clear, long-term benefits in longer running periods and improved dewatering. 

Valmet’s roll covers such as rubber cover Press Roll Cover PT with improved wear resistance, Press Roll Cover VT, a tough composite cover that provides longer cover life, and hard coating Press Roll Cover TM  are recommended for the most demanding conditions.
