Sawdust shredding is an essential stage in the production of pellets and briquettes. The material fed into briquetting machines and granulators must be properly prepared beforehand. In large-scale production, it is necessary to use professional, high-capacity machines for sawdust shredding. Find out which devices are used for this purpose.
What equipment is used for sawdust shredding?
Sawdust is most frequently used for pellet and briquette production and must first be cleaned and dried. This prepared raw material must then be ground into a homogeneous fraction with the correct parameters. Only thorough shredding ensures that the subsequent production stages proceed correctly. Hammer mills, also simply known as sawdust shredders, are used for this purpose. These machines are typically made of steel and feature a relatively simple design consisting of a rotor, hammers, and a screen. The sawdust is fed into the chamber via specialized conveyors. The grinding process itself occurs through the impact of the hammers against the material within the mill chamber, as well as the material striking the chamber walls. Raw material prepared in this way is ready for further processing, leading ultimately to granulation or briquetting.
What are the advantages of using hammer mills?
Thanks to hammer mills, the shredding process is fast and precise. Modern mills are cost-effective to operate, energy-efficient, highly durable, and safe. Some models are equipped with additional features. Most are capable of shredding slightly damp materials, although the machine’s efficiency is lower in such cases. Manufacturers provide throughput ranges that depend specifically on the type of material being processed. For industrial production, this typically ranges from approximately 20 to 80 m³/h. It is extremely important to ensure that the material fed into hammer mills is thoroughly cleaned, as small stones and other hard objects can damage the device or even cause an explosion. Pneumatic and magnetic separators are the most effective solutions for this purpose.
