The stamping sawdust briquetting machine produced by Gongyi Xingfa Electric Co., Ltd. adopts the spiral pre-pressing, piston pressing, secondary compression technology, and强制cooling of engine oil to ensure equipment lubrication. It solves the shortcomings of ordinary straw briquetting machines that require high moisture content in straws and fast wear of forming molds; This equipment has the characteristics of low electricity consumption, high production efficiency, long mechanical running life, and low maintenance rate. Straw briquettes can replace coal, oil and other conventional energy sources, and are widely used in industrial production, institutions, enterprises and institutions, urban residents' heating, residents' cooking, high-end fireplaces, and tobacco farmers smoking. They can also be used as power generation materials for biomass power plants.
