Product Introduction

Primary PU Belt Cleaner – Polyurethane Conveyor Pre-Cleaning Solution

The Primary PU Belt Cleaner is a specialized conveyor belt scraper designed to clean the surface of conveyor belts just after the discharge point at the head pulley. Constructed using high-quality polyurethane materials, this cleaner effectively removes carryback material from the belt surface, reducing system wear and maintenance downtime. As a critical component of a comprehensive conveyor belt cleaning system, it plays a key role in maintaining the efficiency and cleanliness of industrial conveying systems.

Unlike metal scrapers, polyurethane blades offer a softer, more belt-friendly cleaning method, reducing the risk of belt damage while maintaining high cleaning performance. These scrapers are ideally suited for medium-duty applications involving sand, gravel, coal, cement, grain, and more. They are widely used in industries including mining, bulk handling, construction, ports, and agriculture.

Product Features
