A secondary conveyor belt cleaner is designed to remove residual material left on the belt after it passes the primary cleaner. By minimizing carryback, it helps protect the conveyor system, reduce maintenance costs, and keep production areas cleaner. As one of the most important conveyor belt accessories, secondary belt cleaners are widely used in cement plants, mining operations, power stations, and bulk material handling systems. In this guide, Belota explains what a secondary belt cleaner is, its key benefits, the most common types available, and how to choose the right solution for your conveyor system.

What Is a Secondary Conveyor Belt Cleaner?

A secondary conveyor belt cleaner is installed immediately after the primary belt cleaner, typically on the return side of the conveyor near the head pulley. Its main purpose is to remove the fine material, dust, and sticky residue that the primary cleaner cannot completely scrape off.

Unlike a primary cleaner, which removes the bulk of the material at the head pulley, a secondary cleaner performs the final cleaning stage. Using both cleaners together significantly reduces carryback, improves housekeeping, and extends the service life of conveyor components.

Key Benefits of a Secondary Belt Cleaner

Installed after the primary belt cleaner, a secondary cleaner provides the finishing touch by removing remaining material from the belt surface. Key benefits include:

  • Superior belt cleaning: Removes fine particles, wet material, and sticky residue left behind after the primary cleaner, keeping the belt surface clean.
  • Reduced carryback: Prevents material from falling off the return belt, improving housekeeping and reducing cleanup costs.
  • Protects conveyor components: Minimizes material build-up on rollers, pulleys, and other rotating parts, reducing wear and preventing belt tracking issues.
  • Extends conveyor belt life: A cleaner belt experiences less unnecessary abrasion, helping prolong the life of the belt and related equipment.
  • Improves operational efficiency: Reduces maintenance downtime, supports continuous production, and lowers overall operating costs.

Common Types of Secondary Belt Cleaners

Polyurethane (PU) Secondary Belt Cleaner

PU secondary belt cleaners are ideal for conveyor systems that require effective cleaning without damaging the belt surface. The scraper blade is made from high-quality polyurethane and is available in both one-piece and segmented designs to suit different operating conditions.

Its flexible blade maintains close contact with the belt, effectively removing residual material while reducing belt wear. PU cleaners are commonly used in cement plants, food processing, fertilizer production, and building materials industries.

Spring-Loaded Secondary Belt Cleaner

Unlike conventional scrapers, this design features individual PU blades combined with a torsion spring mechanism. Each blade automatically retracts when passing over mechanical belt splices or uneven belt surfaces before returning to its cleaning position.

This self-adjusting design maintains consistent blade pressure across the belt, improves cleaning efficiency, and minimizes vibration. It is particularly suitable for conveyors with mechanical fasteners or reversing belts.

Rubber & Alloy Secondary Belt Cleaner

Designed for abrasive and sticky materials, this cleaner combines wear-resistant alloy blades with a flexible rubber cushion. The rubber absorbs impact while maintaining consistent contact pressure against the belt.

Its segmented blade design allows quick replacement, while the flexible mounting system enables smooth operation over belt splices and on reversing conveyors. This type is widely used in quarrying, cement, mining, power generation, wood processing, and recycling industries.

Tungsten Carbide Secondary Belt Cleaner

For conveyors handling highly abrasive materials such as coal, ore, clinker, and aggregates, tungsten carbide belt cleaners offer outstanding wear resistance and long service life. The tungsten carbide blade maintains a sharp scraping edge even under continuous heavy-duty operation.

Available in solid-blade, segmented, and reversing-belt configurations, tungsten carbide cleaners reduce blade replacement frequency, minimize maintenance downtime, and deliver reliable cleaning performance in demanding industrial environments.

Applications of Secondary Belt Cleaners

Secondary belt cleaners are widely used across industries that handle bulk materials, including:

  • Cement plants
  • Coal handling systems
  • Mining and quarrying
  • Thermal power plants
  • Steel mills
  • Metallurgical plants
  • Building materials manufacturing
  • Bulk cargo ports and terminals
  • Crushing and screening plants
