Abstract: 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.

Abstract: A particulate cellulose derivative is obtained in a process of grinding and drying a moist cellulose derivative wherein A) a cellulose derivative having a moisture content of from 60 to 95 percent, based on the total weight of the moist cellulose derivative, is provided, B) the moist cellulose derivative is dried and partially ground in a gas-swept impact mill; and C) the ground and partially dried cellulose derivative is contacted 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.

Abstract: The present invention relates to a process for the preparation of a water-moist cellulose ether composition, characterized in that water-soluble polymeric additives which contain anionic groups (WSAP), or corresponding additive mixtures, are added to the cellulose ether composition. The invention furthermore relates to water-moist cellulose ether compositions which can be prepared by such a process, and to corresponding milled and dried cellulose ether compositions. The invention also relates to the use of these WSAP or corresponding WSAP mixtures for improving the transportability of water-moist cellulose ether compositions in conveying units.

Abstract: The present invention relates to polysaccharide derivatives having an adjusted particle morphology for use in the preparation of a hydrolytically setting composition having an adjusted lump rating. The invention further relates to a method of adjusting the lump rating of a hydrolytically setting composition comprising adjusting the particle morphology of a particulate polysaccharide derivative. Furthermore, the invention is directed to a hydrolytically setting composition comprising a particulate polysaccharide derivative having an adjusted particle morphology. The invention is also directed to various uses of the particulate polysaccharide derivative having an adjusted particle morphology.
