  • Pin chip recovery
    Publication number: 20090308550
    Abstract: A method is described for separating pin chips from a wood furnish of wood chips, pin chips and fines mixture. In the method, the wood chips are separated from the pin chip and fines mixture and treated with a surfactant to lower the interfacial surface tension between the pin chip and the fibers. The resulting treated pin chip and fines mixture is then mechanically separated into the individual pin chip and fines fraction.
