Wood chips should be crushed

Wood materials are ideal raw materials of biomass pellet fuels, but how wood materials can be pressed into pellet fuels? Yes, pellet mill is the machine that is used to press pellets. But we need to know that pellet mill is usually suitable for small size of wood materials, such as sawdust. So wood chips should be crushed before entering into pellet mill, a wood hammer mill is necessary in the situation. In order to make best biomass pellet fuels, pellet mill has multiple support machines, including hammer mill, separation system, pneumatic handing system, mixture feeder, tempering system, cooling system, conveying mechanism and etc. Today let’s learn something about the crush of wood chips and GEMCO wood hammer mill.

The introduction of GEMCO wood hammer mill

GEMCO is a modern company dedicated to biomass machinery research and development, manufacture, installation and adjustment. Products sell well all over the world, exporting directly to Europe, Southeast Asia, Africa, and more than 50 countries and regions. GEMCO also has offices in the United States, Russia, Ethiopia and other places.

GEMCO wood hammer mill is a kind of advanced crushing equipment that absorbs the advantages of other hammer mills, and it is developed by making full use of impact, shear, impact, grinding and other theories. It can not only process pine, hardwood, fir, bamboo and other wood materials, but also can crush bamboo, grass, corn straw, sorghum stalk, etc. After crushing, the raw materials will become sawdust or powders, which are suitable for pressing pellets.

Operation principle of GEMCO wood hammer mill

GEMCO wood hammer mill can be driven by diesel, electric or fuel. In the crushing chamber, hammer rotates at a high speed. Wood chips are crushed by the hit of hammer and the rub of toothed plate. Through the sieve, the crushed wood materials are sucked into storage bag by centrifugal fan. When the hammer mill is working well, wood chips can be fully and effectively crushed, and the discharging is uniform. What’s more, micro grinding and micro powder separation can finish simultaneously.
