The advantages of the pelleting machine also reside in the fact that the pre-pressing stations and main pressing stations can be formed uniformly and independently from one another, and removed as a structural unit from the pelleting machine.

In other words they can be maintained at a remote place so that meanwhile they can be replaced by similar parts. This is true both for the pressing compactor manufacturer with their bearing and as an enclosed structural unit, as well also for the drive housing with the drive for the pressing roller which must be worked after being separated from the pellet machine, for the purpose of change of maintenance, an exchange of the matrix disc, cleaning or repair.

A further advantage of the above mentioned divisibility is obtained when during a dismounting of a pressing roller it is not necessary to release all electrical conductors and to remove the end switches and therefore it is not necessary to adjust again the whole pressing station. The drive housing for the pressing roller can be releasably connected with a housing of the granulator.
