C4 Classifier

Compact, fast setup and precise, high-quality classifying

Overview

Sand & Gravel

Aggregates

Quarrying

The C4 makes the best precision screening possible, it has a large range of interchangeable screening media available. The set up time is very fast without any support legs. Most compact classifier, available with double and
triple deck screenbox, with interchangable screen meshes on each deck. The best service access and walkways around all sides of the screenbox.
