APPLICATIONS
Warm-air-dryers are used for drying and pre-heating solvent-free synthetic granulates.
Advantages here are:
- enlarged plasticizing capacity
- quality improvement
- quality assurance
- improved flow behaviour
Surface humidity at granulate will be achieved with non-hygroscopic synthetics (e.g. PE, PP,PS, etc.) with unfavourable storage, large temperature differences and condensate with high air humidity. A pre-heating is necessary to remove condense humidity. Several machinery can be served by one dryer.
