Title:
HAMMER MILL ROTOR
Document Type and Number:
WIPO Patent Application WO2001051211
Kind Code:
A3
Abstract:
For the grinding of grain in the agricultural sector it is known to use hammer mills with a hammer carrying rotor construction made as a row of shaft mounted discs, which are kept interspaced by means of smaller shims in such a manner that the interspaces can accommodate outwardly projecting hammers cooperating with a surrounding mill screen being pivotally held on shaft elements extending between the shims near the peripheries thereof. In connection with the invention the spacer shims are changed into ordinary, hammer carrying discs which are only provided with local recesses (6) for receiving the inner ends of the hammers (10), while in places angularly offset from these recesses they carry shafts for hammers mounted outside of each of the adjacent discs, which are at these places provided with corresponding recesses. Accordingly it is possible to provide such a rotor with simple, axially closely juxtaposed hammers all over the length of the rotor, whereby a high efficiency of the mill is achievable.
