Method, for the recovery of wood fiber from compressed fiberboard scrap |
摘要 |
The invention provides a process and apparatus for the treatment and recovery of fiberboard and particle board waste. Waste fiberboard and particle board is fed into a steam chamber and steam treated with steam under pressure from a steam generator. When the steam treatment is completed any effluent and excess steam are evacuated from the chamber and the steam treated waste is passed through a rotating trommel. Woodfibers and woodchips pass through the screens of the trommel and are collected for drying and further processing. Waste material, such as melamine coatings, passes through the trommel for collection and disposal. The collected woodfiber and woodchips can be processed for reuse in paper, cardboard or particle board manufacture or as mulch and other ground cover material.
