Pulp from Shredded Paper

I am so lucky to be able to get shredded paper from the print shop at our local collage
It goes into a blender , you don;t want to know how many blenders I went through in the early days . I learned it is better to not over load , to take my time making pulp It takes me almost two hours to make two buckets of pulp , roughly  120 8x10 sheets of finished paper . I usually make it a two day project , one day for pulp the second day to make paper
