The invention relates to the field of a production method and a device for crushing biomass or wood materials such as crushed wood, straws or stalks into wood chips, sawdust or wood powder. The invention provides a method and a system for crushing a wood material into wood chips and for drying the wood chips. According to the invention, when the wood material is crushed, the temperature of the material can be increased, and water can be separated, such that the water content can reach a requirement. The method comprises the steps that: in a cavity, the wood material is subjected to milling multiple times by using a crushing mechanism; and with the heat caused by friction between the wood material and the crushing mechanism and among the wood material, the temperature of the wood material is increased during milling; the wood material is delivered through the crushing mechanism multiple times, and milling and turning are continuously carried out, such that large amount of heat is produced and is sufficiently delivered to the wood chips, and the temperature of the obtained wood chips can be increased. Also, the wood chips can be heated only by using the heat caused by friction, such that no external heat source is needed. Therefore, energy is saved, and environment pollution caused by combustion is avoided.
Description
technical field [0001] The present invention relates to the field of production methods and equipment for crushing wood chips, straw or wheat straw and other biomass or woody materials into sawdust, wood chaff or wood powder, and more specifically relates to the process of crushing woody materials into wood chips and drying The method and system thereof can increase the temperature of wood chips through friction during the crushing process. Background technique [0002] After crushing biomass materials such as wood chips, straw or wheat straw into sawdust, wood bran or wood powder, they are used to press into pellets and then recycled, such as biomass gas boilers, biomass power generation, etc. A common and very important technical means. The general procedure is to roughly screen all kinds of leftover wood chips, and then place them in a wood material crushing and drying system for crushing to make wood chips, wood bran or wood powder, and then carry out further processing...
