We recommend you inspect your hammer mill screens regularly. Hammer mill screen maintenance is especially important if you are running abrasive or hard materials. The decision to replace your hammer mill screens will depend on several factors including the type of material you are processing, the wear life of your screens, and the frequency of use.
Air volume in m3/min. = Screen area in dm2 x 0,70. When deciding the fan size, we should keep in mind that a hammer mill has a resistance of about 10-15 m bar. A reduction in the air flow rate leads to a reduction in mill capacity, finer product, higher specific energy consumption, greater heating during milling, greater wear, greater dust ...

This is the particle size at which 50% ...
Screen hole size. By far, the most important feature of a screen is hole size, which refers to the size of opening through which a particle will pass. The larger the hole, the larger the particle size output. Remember that a sizing screen's purpose is to provide retention time and impact surface, not to classify the material.
