Dispersion and refining

Dispersion-and-refining-1296x412.png

Optimal dispersion technology improves pulp quality by reducing the particle size of undesirable contaminants affecting the downstream processes in recovered fiber systems. In demanding OCC processes, dispersion also improves fiber strength and machine runnability. Accurate refining provides smooth board machine running and determines quality and final product properties. Valmet’s OptiFiner family includes both conventional conical and double-disc refiners, securing stable operation and a uniform refining result.

Dispersion

Dispersion

The optimized design of the disperger fillings provides wide power adjustability, with their conical form providing a larger processing area and longer treatment time than other disperger types

Refining

Refining

Valmet’s refining experience dates back to the early 1950s, with both conventional conical and double-disc refiners.
