Introduction Intended use Sample cleaner MLN helps in determining the total dockage (German = Besatz) associated with grain crops and grading the said crops. The cleaning process largely corresponds to that of a normal cleaning machine. The proportion of impurities (coarse particles, fine particles, aspiration discharge), that of small grains and that of quality grains can be determined with the help of a sample at the time of acceptance.
This declaration shall become null and void should any alterations be made to the machine without our approval. Kitzingen, __________________________ _________________________________________ Lothar Pfeuffer, General Manager 6 | 38 Operating instructions sample cleaner MLN | Revision 3...
