SPIRAL SCREW CONVEYORS WITH WEAR PROTECTION OR WITH NON-STICKY LAYER
The harshest conditions, to which PURATEK spiral conveyors are exposed, require a special wear protection of the sliding insert in the conveying trough and often also a wear protection of the conveying spiral. A special wear protection has a significantly higher resistance than the synthetic material usually used for sliding inserts, such as PE1000 or similar.
Chemically aggressive, sticky, or extremely abrasive materials to be transported must be given special consideration to.
In close cooperation with a well-known manufacturer of engineering plastics, the polyurethane-based PURATEK-care® synthetic material was developed. PURATEK-care® consists of two components: Diisocyanate (hard component) and polyol (soft component). During the reaction of the two components, a number of specific additives are added, resulting in the outstanding properties of PURATEK-care® wear protection:
- High resistance to abrasion
- Non-sticky properties
- Easy to clean
- Sound insulation
- Low specific weight
- High mechanical strength
- High chemical resistance
- Good sliding properties
In a comparative test with the PURATEK-care® sliding insert, a service life of up to 8 times longer was achieved compared to the conventional PE-HD-PE sliding insert material. The excellent chemical resistance to the vast majority of substances was proven in the laboratory of our development partner.
PURATEK-care® does not only provides lasting operational reliability for your spiral conveyor, but it is also very economical.
PURATEK-care® is an investment in wear protection with a rapid payback effect. PURATEK-care® can also be retrofitted without any problems to existing conveyors.
