How Many Types of Scrapers Are in a Conveyor Belt?

Key Takeaway: Types of Conveyor Belt Scrapers at a Glance

Type	Purpose	Material	Best For
Primary Scraper	Removes bulk material at discharge points.	Polyurethane, Tungsten Carbide	General cleaning needs.
Secondary Scraper	Cleans residual material after the primary.	Tungsten Carbide, Rubber	Fine cleaning and high precision.
Return Belt Scraper	Cleans the underside of the belt.	Polyurethane	Underside debris removal.
Brush Scraper	Rotating brushes for specialized cleaning.	Nylon, Polypropylene	Sticky or fine materials.

Why Are Conveyor Belt Scrapers Important?

Conveyor belt scrapers are indispensable in industrial operations. They reduce carryback, a common issue where leftover material sticks to the belt and falls off at unintended locations. Carryback wastes valuable material and causes operational inefficiencies, increased cleaning costs, and safety hazards.

Industry Insight: Research suggests that without proper scrapers, up to 3% of material can be lost daily due to carryback. This loss is particularly significant in industries like mining, where throughput is high.

Types of Conveyor Belt Scrapers Explained

1. Primary Scrapers

Purpose: Remove most of the material at the discharge point.
Material Options: Polyurethane for flexibility; tungsten carbide for durability.
Best For: Heavy duty applications like mining or sand production.

2. Secondary Scrapers

Purpose: Handle residual material left by the primary scraper.
Material Options: Rubber for softer cleaning; tungsten carbide for precision.
Best For: Conveyor systems requiring high cleanliness levels.

3. Return Belt Scrapers

Purpose: Clean the underside of the conveyor belt.
Material Options: Polyurethane.
Best For: Preventing material build-up on the return rollers.

4. Brush Scrapers

Purpose: Use rotating brushes for cleaning fine or sticky materials.
Material Options: Nylon or polypropylene brushes.
Best For: Applications like food processing and fine powder handling.

Choosing the Right Scraper for Your Conveyor System

When selecting a scraper, consider the following:

Material Being Handled: Is it abrasive, sticky, or fine?
Operating Environment: Is it wet, dry, or corrosive?
Budget: Durable materials like tungsten carbide have a higher initial cost but longer lifespan.

Common Questions About Conveyor Belt Scrapers

Q1: How Often Should Scrapers Be Inspected?
Regular inspections should occur at least once a month to check for wear and alignment.
Q2: Can I Combine Scraper Types?
Yes, combining primary and secondary scrapers enhances cleaning efficiency.
Q3: What’s the Lifespan of a Scraper?
Tungsten carbide scrapers can last up to five times longer than polyurethane alternatives.
