Latest Patents

One of Johansson's latest patents is a rotary grinding disc for defibrating apparatus. This invention features a rotary grinding disc designed for refining fibrous pulp material. It comprises a plurality of arcuate grinding plate segments arranged annularly around the disc. These segments are supported by wedge-shaped tongues that project from the segment plates and dovetail into grooves of corresponding profile in the disc. The design allows for the wedge-shaped tongues and dovetail grooves to decrease in width from an outer radial portion toward an inner radial portion, or vice versa, effectively wedging the plate segment into the disc. Additionally, the plate segments are secured against displacement by centrifugal force during rotation, aided by a peripheral ring that engages the wedged tongues.
