Exterra® Primary
Belt Cleaner

Meat and Potatoes
Aggregate primary belt cleaners — also known as pre-cleaners — are designed for installation at the head pulley just past the point of material discharge from the conveyor.
Superior’s Exterra Primary Belt Cleaner, as a urethane-based cleaner, scrapes the top of the belt and forces coarse carryback material onto the stockpile or into another intended target.
Without this primary belt cleaning stage, which typically removes about 70% of carryback, fugitive material will stick to return rolls, pile up below the conveyor and create costly maintenance issues like belt mistracking and damaging spillage.
- Belt widths 18” – 72” (457 – 1,828mm)
