A method of making a paper product can comprise making one or more sheets at least by, for each of the sheet(s), forming a web from one or more furnishes that comprise fibers dispersed in water. The fibers of the furnish(es) can comprise a plurality of first fibers that are hardwood fibers and a plurality of second fibers that include softwood fibers and surface enhanced pulp fibers (SEPF), the SEPF having a length weighted average fiber length of at least 0.20 mm. The method can comprise at least partially dewatering the web to form the sheet. The sheet(s) can be laminated and/or embossed such that a total dry tensile strength of the paper product is less than or equal to 90% of the sum of the total dry tensile strength(s) of the sheet(s).

The invention relates to a method for producing microscale and/or nanoscale fiber material. The method has at least the step of dispersing (5) dried pre-comminuted pump in a liquid. The method additionally has a step of finely comminuting (6) the pulp dispersed in the liquid such that a fine comminution mixture is produced which contains the liquid and the fiber material with the microscale and/or nanoscale fibril agglomerates.

The shear gap between a rotor and a stator in a colloid mill is adjusted by translating the stator with respect to the rotor, preferably by moving the stator along a helical path about the rotor, thereby moving the stator's surface closer to or further from the rotor's surface (and altering the shear gap therebetween). Helical slots are provided in the casing about the stator, with members extending from the stator through the slots, whereby the members can be grasped and rotated about the casing to move the stator. Channels allowing circulation of buffer fluid are provided about the stator and rotor to deter ingress of the fluid being processed into junctures between components of the colloid mill.

The present invention relates to a method for processing grass or hay as paper pulp having the steps of pre-reducing the grass or hay with a bale breaker and/or a shredder to an average fiber length between 500 mm and 10 mm, preferably between 120 mm and 10 mm, removing impurities and foreign or extraneous substances by means of a cyclone; reducing and fibrillating the grass or hay in a fiber mill, fraying the grass or hay; and screening and/or sifting the grass or hay by means of a circulating-air separator and/or a cyclone screener.

A screen cylinder includes a cylindrical screening media formed of a plurality of circumferentially spaced an axially extending wedgewire bars, which have an inflow surface facing an inflow side. The axially extending wedgewire bars have a profile shape optimized to apply a spray on wear resistant coating on their inflow surface using a spray nozzle. To apply the coating the angle of the spray nozzle is varied in the circumferential direction relative to the inflow side of the screening medium to change the spray angle of the nozzle to apply the coating sprayed on the bars.
