Primary Belt Cleaner

Product Overview

ZOOMRY primary Belt Cleaners (polyurethane) are installed at the head pulley discharge zone to remove bulk material from the belt surface. They prevent carryback, reduce material spillage, extend Conveyor Belt life, and improve overall conveyor efficiency. When paired with a secondary belt cleaner, the two-stage system removes up to 95% of residual carryback material.

How to Select the Right Primary Belt Cleaner for Your Conveyor?

Choosing the right primary belt cleaner depends on three factors: belt width, material characteristics, and operating environment. The polyurethane blade offers an ideal balance of wear resistance and gentle belt contact for most mining, cement, and aggregate applications. For highly abrasive materials, consider upgrading to tungsten carbide blade tips.

Advantages

Smooth welding region – free of bubbles and imperfections, resulting in higher bearing capacity.
Improved wear resistance – polyurethane cleaner blade has no surface bubbles, enhancing durability.
Wide temperature range – operates reliably from -45°C to +60°C.
Flexible blade options – choice of cleaning blades for fixing slots and aluminum cores.
High‑strength carbon steel – manufactured using 35# high strength carbon steel.
Quick blade replacement – optional built‑in cleaner blade design allows faster changeouts, reducing downtime.

How Does a Primary Belt Cleaner Fit into a Complete Cleaning System?

A primary belt cleaner is only the first stage in an effective conveyor cleaning strategy. For best results, combine it with a secondary belt cleaner positioned further down the return run, and a V-return belt cleaner to capture debris on the non-working surface. This three-stage approach is widely used in coal handling, iron ore processing, and aggregate quarrying where carryback control directly impacts operational safety and maintenance costs.

Common Applications for Primary Belt Cleaners

ZOOMRY primary polyurethane belt cleaners are deployed across multiple heavy industries:

Mining and quarrying – cleaning abrasive ores, crushed rock, and minerals from conveyor belts at transfer points.
Cement and clinker plants – handling sticky raw meal, hot clinker, and dusty finished cement.
Coal handling and power plants – maintaining clean belts for continuous fuel supply to boilers.
Fertilizer and chemical processing – where material buildup on belts can lead to corrosion and contamination.
Ports and terminals – high-capacity belt cleaning for ship loading and unloading operations.
