  • Patent number: 5203965
    Abstract: A screening system incorporated into the system of sawdust collection for paper producing pulp. An upper and lower range of the sawdust particles is designated as between smaller, strength-inhibiting size particles and larger strength-enhancing size particles. A screen is provided to screen out the smaller size particles. The screen is made out of stainless steel to avoid rusting and corroding and also to more readily pass the moistened smaller size particles. The screen is sloped and agitated to induce shuffling of the sawdust mixture, the process of which results in a separation of about 50% of the particles as rejected smaller size particles and 50% as acceptable larger size particles desirable for paper producing pulp.
