Hammer mills are a sort of size reduction machine that is used to break down granular materials that are too large. Breaking down large materials aids in the production of feedstock with an optimal particle size distribution. In nutshell, wood hammer mill is a type of multipurpose wood crushing machine that can be used to grind small diameter materials such as corn straw, branches, herbs, and other materials with a diameter of less than 50mm and a fineness of 3-5mm after grinding. It is widely used in wood pellet plants and biomass briquette manufacturing lines because of its advanced technology, high quality, and reasonable pricing.
