Mode of operation
THE UNIQUE WORKING PRINCIPLE
The material is fed to the UNIclean B 12 where it is picked up by special pins and passed fi ve times mechanically over the cleaning grid. During the process the raw material is guided over the integrated dust extracting filter where dust, fi ber fragments and fi ne trash particles are stripped off mechanically.
The combination of newly developed grid bars, optimized material flow and increased dedusting area guarantees an effi cient cleaning effect also at high rates of production. The cleaning process is not affected by air currents and is thus controlled and effective.
Only approx. 0,5 m3/s of dust-laden air has therefore to be removed. The trash removed drops into the waste chamber and is transferred to the waste removal system by an airlock cylinder.
Since the UNIclean B 12 occupies little space it can be incorporated easily into other manufacturers’ lines. Thus the cleaning performance of existing installations is enhanced.
Eff ective cleaning and dust extraction
CLEANING CONCEPT
The UNIfl oc supplies very small tufts of material. The
UNIclean exploits this large surface area. Located immediately downstream from the bale opener, the UNIclean removes loose trash particles, fi ber fragments and dust. It is designed for intensive cleaning. The subsequent process stages have to remove only a small fraction of the trash. At the same time the fi bers are treated gently. Results in practice have shown fi ber
yields to be up to 2% higher than when conventional blowroom lines are used. That pays off .
OPTIMUM CLEANING
High cleaning performance and low losses of good fi ber can be quickly checked by visual waste control. The quality of waste removal can also be assessed whilst the machine is in operation.
| SIMPLE AND REPRODUCIBLE SETTINGS Two independent setting parameters: cleaning intensity and relative quantity of waste, are the secrets of the selective cleaning action of the UNIclean B 12. Each of the VarioSet 110 working points corresponds to one setting of material speed and grid angle. Compared to conventional lines fiber yield is increased while effective cleaning is performed. VERY EASY OPERATION Two values are entered to the VarioSet: cleaning intensity set between 0,0 and 1,0, and relative quantity of waste set between 1 and 10. These values are entered directly into the machine itself or are loaded via the control system. The machine settings are made automatically, even whilst the machine is in operation. The settings are reproducible. This provides a high level of operating convenience when batch changes are frequent. UNIQUE MULTI-ASSORTMENT OPERATION The material-specific working point is selected automatically on the UNIclean if the UNIfl oc is opening different assortments. |
