1. Why Belt Cleaner Selection Matters
In mining, cement, aggregate, and bulk material handling industries, the right conveyor belt cleaner is essential to reduce carryback, prevent belt misalignment, and extend equipment life. An optimized belt cleaning system can reduce downtime, improve safety, and cut maintenance costs. This guide covers how to choose primary, secondary, and return cleaners for wet & sticky, dusty, and corrosive materials.

2. Types of Conveyor Belt Cleaners
Belt cleaners are categorized by blade material and installation position.
By Blade Material
- Polyurethane Scraper: One-piece or segmented, belt-friendly, durable, suitable for light/medium duty.
- Tungsten Carbide Scraper (Segmented): High hardness, ideal for high-speed and heavy-duty applications.
- Ceramic Scraper: Excellent abrasion resistance and chemical stability, long service life in harsh environments.

By Installation Position
- Primary Cleaner: Removes most carryback at the head pulley.
- Secondary Cleaner: Scrapes fine residues left by the primary cleaner.
- Return Cleaner (V-Type/I-Type): V-type removes large lumps; I-type removes fine particles on the return belt.

3. Cleaner Selection by Material Type
A. Wet & Sticky Materials
Example: Clay, wet coal, bauxite.
Primary: Polyurethane scraper (one-piece)
Secondary: Segmented tungsten carbide scraper
Return: V-type cleaner
B. Dusty & Fine Powder Materials
Example: Cement, limestone, fly ash.
Primary: Polyurethane scraper (segmented)
Secondary: Ceramic scraper
Return: I-type cleaner
C. Corrosive & Chemically Aggressive Materials
Example: Fertilizers, salts, acidic ores.
Primary: Chemical-resistant polyurethane scraper
Secondary: Ceramic scraper
Return: V-type cleaner with stainless steel frame
4. Real-World Case Studies
- Wet & Sticky: A coal mine in Indonesia reduced carryback by 70% after switching to a polyurethane + tungsten carbide combination.
- Dusty: A cement plant in Vietnam extended belt life by 40% using ceramic secondary cleaners.
- Corrosive: A fertilizer plant in Saudi Arabia minimized blade replacements by using chemical-resistant polyurethane.
