LB manufactures and supplies complete granulation lines for various industrial sectors, i.e. for fertlizers.
The product to be granulated is collected from an existing container to be conveyed to granulator GRC granulator by LB by means of a batching system.
The granulated product is then conveyed to the drying line and, later, to an existing or new storage system.
After the dryer, you find the sieving tower: the material above the net is re-circulated and goes into a mill crushing the bog pieces and putting them again imnto the sieving cycle. The “good” material (below the net) goes directly to the storage silos.
The compaction is made through a compacting machine (series Fyster 400/600): this machine produces a tablet broken with a “mill” with a very high crushing machine in a very limited time to get flakes and to decrease the powder produced (the powder d 97<500 micron for this type of process is considered to be waste).
