Factors when Choosing Screen - Part 2 Mesh Size

In a previous article we discussed the RDW weave patterns and how the screen will behave differently depending on the weave pattern design. This is an important factor to assure consistent flow of the melt polymer through the continuous belt screen changer. However, it’s not the only factor. The mesh size also plays a crucial role in assuring consistency of the melt.

We discussed the four basic types, how they differ, and how they evolved into the RDW style which offers the combination of strength and durability required for continuous belt screen changers. However, there are other factors to consider when choosing screen. The RDW weave pattern is one of them.
