Abstract

"PROCESSO PARA ALTERAçãO DE FIBRAS DE PAPEL OU FIBRAS DE CELULOSE EM UMA SUSPENSãO AQUOSA". A invenção se refere a um processo que serve para alteração de fibras de papel ou fibras de celulose em uma suspensão aquosa, em particular para elevar a resistência do papel produzidos a partir destas fibras. Neste caso, duas superfícies de moagem são pressionadas uma contra a outra e movimentadas de tal maneira, que uma menor possível velocidade relativa prevalece entre as superfícies de moagem e o material fibroso (F) na zona de moagem. Uma realização do processo especialmente favorável pode ser realizada com os corpos de moagem que portam uma superfície de moagem, os quais são rolados sobre o lado interno de um tambor de moagem que porta a superfície de moagem."PROCESS FOR CHANGING PAPER FIBERS OR CELLULOSE FIBERS IN A WATERY SUSPENSION". The invention relates to a process for altering paper fibers or cellulose fibers in an aqueous suspension, in particular for increasing the strength of paper produced from these fibers. In this case, two grinding surfaces are pressed together and moved in such a way that a lower possible relative speed prevails between the grinding surfaces and the fibrous material (F) in the grinding zone. An especially favorable embodiment of the process may be performed with the grinding bodies carrying a grinding surface which are rolled on the inner side of a grinding drum carrying the grinding surface.
