Ferrules and finishes

A wide range of brackets for longitudinal tension ensures correct installation of PROGRESS string screens on all types of vibrating sifters and sorters. In the case of TYP-PU non-sliding bands, it is necessary to precisely determine the spacing of the supports. In other types of string screens, it is enough to specify the number and type of bands. Their adjustment takes place during assembly on the sifter.

The woven screens used in various conditions require the use of the highest quality spring and stainless steel, as well as hard wearing abrasive bands. Their immediate accessibility is ensured by our material policy, and optimal selection by the support of our Construction and Technology Department.
