摘要：
A particulate cellulose derivative is obtained in a process of grinding and drying a moist cellulose derivative which comprises the steps of A) providing a cellulose derivative having a moisture content of from 60 to 95 percent based on the total weight of the moist cellulose derivative B) grinding and partially drying the moist cellulose derivative in a gas swept impact mill and C) contacting the ground and partially dried cellulose derivative with an additional amount of a drying gas outside the gas swept impact mill. The obtained particulate cellulose derivative has a high untapped bulk density and a good flowability.
