Since the beginning of trash screening, polyester screen cloths have been the key factor in the process. The polyester is reliable due to its wear resistance and flexibility. About 98% of all linear screens worldwide use polyester screen cloths.
There is however an alternative, a screening process developed by Particle Separation Systems utilizes Stainless Steel Belts to improve screening accuracy and efficiency. When comparing a 600 micron polyester screen cloth with a 500 micron stainless steel belt, several key differences can be seen, the most notable are:
· Higher drainage rates
· 35 % higher open area
· More accurate apertures
· Unaffected by high or low PH
· Unaffected by high temperature
Due to the higher drainage rate and open area, screening can be slowed down dramatically which increases cleaning efficiency, and reduces/slows down all moving parts deterioration, saving on bearings and rollers and motor wear.
