  • PROCESS FOR PRODUCTION OF MICRO FIBRILLATED CELLULOSE
    Publication number: 20150090412
    Abstract: A method for producing micro fibrillated cellulosic material from pulp in which a pulp feed material is pre-treated by passing through a high consistency refiner a single time, followed by dilution and multiple passes through low consistency refiners.
