Abstract

The invention provides a production process of wood pellets from miscellaneous tree materials. According to different shapes, the wood materials comprise undressed lumber, crotches, branches, woodchips, and wood materials with shaped of lump, chipping or powder. Respectively employing Methods of slicing, crashing and sieving or relative combined method, processing wood materials with different shapes into chippings with particle size of 3-4mm, mixing wood materials with high lignin content with wood materials with low lignin content by mass ratio, wherein raw materials of hardwood is 60-90, various saw dust is 5-20 and various wood shavings is 8-15, after being dried, molding the mixture by granulating. The invention has rich source supply, is not limited by materials of tree species. Inexpensive materials of tree species can be chosen to collocate flexibly to meet the requirement of low-cost production. Not only the manufacture cost is reduced, but also the mechanical strength of produced wood pellets are ensured to conform to Swedish wood pellets standard.

Description

Technical field: [0001] The invention discloses a wood particle production process of miscellaneous wood raw materials, which belongs to the technical field of wood particle fuel molding processing. Background technique [0002] In recent years, the research and production of wood pellets in my country has been vigorously developed by the shortage of the European pellet fuel market. However, the production of wood pellets in many enterprises is still limited to the production of a single species of existing wood processing waste, and the amount of resources is far from enough for the market. demand, and competing with the edible fungus industry for sawdust raw materials, resulting in a sharp rise in raw material prices in some areas, resulting in a sharp increase in production costs. On the one hand, the market is in urgent need of this product, and on the other hand, the increase in raw material prices has made the company unprofitable. The production company is in a dilemma....
