Traditionally screen cloth was made with metal wires woven with a loom. Today woven cloth is still widely used primarily because they are less expensive than other types of screen media. Over the years different weaving techniques have been developed either to increase the open area percentage
Because impact is the primary force used in a Hammer mill to reduce the size of the particles anything that increases the chance of a collision between a hammer and a target increases the magnitude of the collision or improves material takeaway would be advantageous to particle size reduction.
Additionally some mill rotor assemblies can be reversed to adjust for specific product behavior while the rotation of the mill remains unchanged. For some hammer mills particle size is determined based on the screen size that is chosen for the mill. Modern hammer mills can reduce material size to as small as 0.2 mm to 3 mm.
We are leading manufacturer of Full Circle Hammer Mill screen translates to a larger screen open area and thus the highest possible production rates on materials that do not require initial grinding against a breaker plate.
