Abstract

Se describe un derivado de celulosa particulado que se obtiene en un proceso de molienda y de secado de un derivado de celulosa húmedo que comprende las etapas de A) proporcionar un derivado de celulosa que tiene un contenido de agua de 60 a 95 por ciento, con base en el peso total del derivado de celulosa húmedo, B) moler y parcialmente secar el derivado de celulosa húmedo en un molino de impacto con barrido de gas; y C) poner en contacto el derivado de celulosa molido y parcialmente secado con una cantidad adicional de un gas de secado fuera del molino de impacto con barrido de gas. El derivado de celulosa particulado obtenido tiene una alta densidad aparente no compactada y una buena fluidez.
