ClaimsThe invention claimed is:1. A process for grinding cellulose prising feeding raw cellulose material in the form of a cellulose web continuously at a controllable constant speed to a grinding unit and uniformly moistening the raw cellulose material with a prescribed amount of liquid prior to grinding wherein the amount of liquid is so measured that the dry weight content of the moistened raw cellulose material amounts to 70 to 95 % by weight and the tensile strength of the cellulose web is retained, and the grinding of the cellulose prises cutting and the cellulose is cooled by a stream of gas during the grinding operation. 2. The process as claimed in claim 1, wherein the liquid for moistening the raw cellulose material is water which evaporates during the grinding and cools the cellulose. 3. The process as claimed in claim 1, wherein the ground cellulose has a limiting viscosity number LVN of 90 to 97 % of the value of the limiting viscosity number of the unground cellulose. 4. A process as claimed in claim 1, wherein said process prises grinding cellulose material into individual fibers and said process preserves the original fiber length of the raw cellulose material. 5. A process according to claim 1, said process further prising setting the controllable constant speed so that less than 20 seconds elapses between moistening and grinding. 6. A process according to claim 1, wherein the ground cellulose is fed to a pulp cyclone and the walls of the pulp cyclone are kept higher than . C. for coniferous cellulose and higher than . C. for linters. 7. A device for carrying out the process as claimed in claim 1, which prises a moistening unit, a grinding unit, a grinding unit ventilating fan, a first conveying mechanism which conveys the raw cellulose material to the moistening unit, a second conveying mechanism which conveys the moistened raw cellulose material from the moistening unit to the grinding unit and a sieve unit wherein each of the first and second conveying mechanisms prise one or more rolls and one or more of the rolls is/are connected to a controllable drive. 8. The device as claimed in claim 7, wherein the moistening unit consists of: (a) a storage vessel for the liquid with which the cellulose web is moistened, (b) a bath which is connected to the storage vessel by a pipe, (c) a valve controlled by a level device which controls the flow of the liquid into the bath and which maintains the level of liquid at a particular constant height, (d) a driven moistening roll the length of which is equal to or longer than the width of the cellulose web to be ground and which is aligned across the cellulose web, where 30 to 80 % of the cylindrical surface of the roll is submerged in the liquid and where the upper part of the moistening roll contacts and moistens the cellulose web along a line parallel to its longitudinal axis, and (e) a drive by means of which the rotational speed of the moistening roll and also at the same time the amount of liquid transferred to the cellulose web can be controlled. 9. The device as claimed in claimed 7, which prises: (a) a storage vessel with a liquid for moistening the cellulose raw material, (b) a main pipe which is connected to the storage vessel, (c) a controllable valve in the main pipe to adjust the flow of the liquid, and (d) one or more nozzles arranged in a distribution pipe where the distribution pipe is connected to the main pipe. 10. The device as claimed in claim 7, wherein the grinding unit
