Sieves configuration: The sieves (or screens) of the hammer mills are usually perforated steel sheets of 2 - 3 mm. thickness, with holes whose diameter is usually equal to or less than the diameter of the pellet.Larger holes mean higher open area, and therefore increased throughout a performance, reduced specific power requirements, coarser …
Process. 71 (2003) 147–166 149 To overcome these limitations, a new energy-based model for swing hammer mills was developed at the Julius Kruttschnitt Mineral Research Centre (JKMRC). This model consists of a crusher model with dual-classification function and a mechanistic power model to determine the dynamic internal recirculating load.

The hammer mill is the best known and by far the most widely used crushing device employing the impact principle of breaking and grinding stone. Thus far we have described machines which do a portion of their work by impact, but the only machine described in which this action plays an important role was the sledging roll type and …
Overall, hammer 2 produced the best improve-ments in grinder capacity, with an average improvement of 200%. Although the hammer 1 design did not per-form as well as the baseline hammer for switchgrass, it is likely that the moisture content caused the decrease in performance rather than the hammer type.
