The bale compression increases as more material is force fed into the chamber and the bale becomes evenly firm and stable. Only relatively low power is required to compress material in this way. Softer and smaller material fragments surrenders and embeds larger and harder objects during the compression process.

Pressing
The material is fed into the baler chamber via a feed conveyor, and is force fed between the upper and lower baler chain mats. The uncompressed material is rotated around the axis of the chamber and as more material enters, the chamber compression of the material increases. The computer system monitors the compression, by measuring the hydraulic pressure in the system. The operator sets the compression level required for the baled material via the computerized system.

Netting
When full chamber pressure is reached, a net is wounded around the bale. The net is fed into the chamber by means of jet air nozzles. The net wound around the surface of the bale keeps its form and prevents the compressed material from expanding when the chamber is opened. The operator sets the required number of windings of the net and the computer system checks continuously that the net is properly fed.

Transfer bale to wrapper
The baler chamber opens and the heads of the chamber are pressed towards each circular end of the bale to hold it firmly during transfer to the wrapping unit. The net wrapping and the high bale compression minimises material loss.

Wrapping
The bale is wrapped with a thin, strong and stretchable plastic film that is airtight and water resistant. The wrapping is made by means of a sweep arm that rotates on the wrapping table to give a 50% overlap of film on the bale. While the bale is wrapped, the heads of the bale chamber turns to the baling position. The bale chamber closes and new material is fed into the baler. When wrapping is completed, the film is cut and the bale is loaded to the bale conveyor.

Unloading
The wrapped bale is tilted onto a bale conveyor for unloading to further transportation or storage. If the conveyor is equipped with a scale and a marking unit, each bale can be marked with weight, material type etc or with a bar code.

(TO BE TRANSLATED)Pressen kan ställas upp på en stationär plats eller flyttas mellan olika anläggningar. Den är försedd med lastväxlarkrok och kan enkelt flyttas med lastbil.

När pressen används på fler anläggningar är det praktiskt att bara flytta själva pressen och låta transportörerna stå kvar. Överflyttningen kräver då mindre tid och pressen kan snabbt anslutas till varje anläggningslösning.

Om upptagningsområdet är stort och det finns ett flertal platser där pressen skall användas är det en fördel att placera pressen med transportörer på en trailer. Trailern kan utrustas med en gripkloförsedd kran som används både till att mata pressen och till att stapla de färdiga balarna. En entreprenör blir då inte beroende av om en hjullastare finns tillgänglig, utan arbetar helt självständigt på de olika pressplatserna.

The mobile round baling system is especially adapted for easy transport, quick installation and quick dismantling, enabling operation of the system at different locations. The baler and conveyors are mounted on two hook lift frames and the combination conveyor is equipped with a separate hydraulic system used during installation and dismantling.
