In the feed industry, a distinction is made between the grinding of feed mixtures and individual feed components. The reason for this are the different surfaces and consistencies that can be found in the individual components of a feed mixture, while the individual feed components are largely homogeneous. For KAHL hammer mills, grinding of neither product is a challenge. This type of mill is also frequently used in grain processing. There are many reasons for this:
The hammer mill is characterised by simple operation and handling. The machine works according to the principle of crushing by multiple impact, so that the most effective crushing takes place by the direct impact of the hammer mill beater on the product. The circumferential speed of the beater tip is approx. 360 km/h. Accordingly, screen perforations, beater designs, beater arrangements and speeds can be adapted to the structure and fineness of the end product. The final size of the grain is determined by the setting of the screen hole diameter and the mill speed. The product only leaves the hammer mill when it is smaller than the screen hole diameter - in approx. 95% of cases the products are smaller than half the screen hole diameter.
