BIN ARRANGEMENT FOR THE COLLECTING AND DISCHARGING OF SMALLER LIGNO-CELLULOSIC MATERIAL

摘要

The invention is related to a bin arrangement(1) for collecting and discharging smaller ligno-cellulosic material. The bin includes a transition part from a circular section of the bin and downwards to a rectangular section with a long and short side of said rectangular section. The transition part could be built with few wall segments, thus needing less welding. According to the invention is a rotary pocket feeder (40) with at least one shaft extending parallel to the long side arranged directly under the rectangular section, enabling a uniform feed from the bin. The use of a rotary pocket feeder with this design directly under the bin do not destroy the even feed of material trough the bin part, which otherwise is experienced from using feed screws feeding material in a transverse direction from the bin outlet, and the bin do not need to have a complex bin design which converge to a small circular inlet to a conventional rotary pocket feeder.
