Middle-consistency vertical pulpers MCV are designed for a highly intensive periodical pulping of white waste paper and liquid packaging board type Tetrapak with a consistency from 10 to 15 %. The pulper output depends on the type of pulped material, way of operation and working cycle structure.

Design

All pulper types are based on the same design. Individual types differ in the tank capacity, in the size of functional elements and in motor type.

MCV-XX-W
pulping of contaminated materials (waste paper)

MCV-XX-T
pulping of Tetrapak type materials

Rotor types

HC – for medium consistency pulping

Rotor lower functional leading edges comprise of bolted blades. The primary advantage of this design arrangement lies in fast and easy replacement of worn blades.
