Machines that reduce the size of a material also erode the grinding elements. In general, the more abrasive the material you grind, the more quickly the internal parts wear. To ensure efficient operation and longevity of your Hammer mill, it’s crucial to regularly inspect and replace its wear parts.
These components include hammers, rods, screens, bearings, and wear plates. In this guide, we will walk you through the steps of replacing your screens or grates to ensure your hammer mill continues to operate efficiently.
