Kinds and properties of the milled wood intended for bin storage

The review proves the necessity of studying the process of the expiration of crushed wood from bins. Modern technologies of wood raw materials processing lead to the formation of waste in the form of crushed wood. The introduction of non-waste production technologies leads to the involvement of these wastes in further processing. In the pulp and paper industry, manufacturing of wood chips is the most important stage of the technological process. Chips for the production of pulp and wood pulp, wood dust, sawdust must be stored. The storage conditions should be such that the quality of raw materials does not decrease, the environment is not damaged, and fire safety requirements are observed. For these purposes, closed storages are used - bins. Types of crushed wood stored in bins are considered. It is established that at present the main types of raw materials stored in bins are chips, shavings, sawdust, screenings. When storing loose materials in closed warehouses and transporting in bulk, loose materials cake, adhere to the walls of containers and form vaults. The existing methods of combating pivot formation are either dangerous or energy-intensive. The actual direction of research in this area is the development of such bins, which do not require the use of manual labor and special devices. Their design should ensure uninterrupted unloading of the crushed material. The process of feeding loose material from the bunker is poorly understood. The available data describing them as loose materials are analyzed. Areas of research are outlined.
