Belt scrapers are essential components in conveyor belt systems, used in various sectors to ensure efficient and clean operation. Here’s a breakdown of the different types of belt scrapers, their applications in different sectors, and the features and benefits that make them important:

What are the different types of belt scrapers?

Primary Belt Scrapers:

These belt scrapers are positioned against the belt immediately after the material discharge point. They feature rigid blades for effective scraping used for the initial removal of material adhering to conveyor belt surfaces.

Secondary Belt Scrapers:

Secondary scrapers are located further down the conveyor system. They feature softer, more flexible blades and are designed to remove finer particles that the primary scraper missed.

Tertiary Scrapers:

Employed in situations where extremely clean belts are required and often used in conjunction with secondary scrapers. This is to ensure almost all residual material is removed.

Motorised Belt Scrapers:

Utilise brush-like structures for gentle scraping. Ideal for delicate materials or belts that require a softer touch. Prevents material getting stuck to return belt and material build-up on return rollers.

V-Plow Scrapers:

Positioned at the tail pulley to clean the underside of the belt. It prevents material buildup that could damage the belt or pulleys.

Features and Benefits:

Efficiency
– Improve operational efficiency by reducing material carryback.

Belt Protection
– Reduce wear and tear on the conveyor belt by removing abrasive materials.

Reduced Maintenance Costs
– Decrease downtime and maintenance requirements.

Enhanced Safety
– Minimise risks associated with material buildup and spillage.

Improved Cleanliness
– Keep the work environment cleaner and reduce material loss.

Versatility
– Suitable for various materials and environmental conditions.

Importance of Conveyor Belt Scrapers

Prevent Material Buildup: This is critical for avoiding material buildup that can cause belt misalignment and damage.
Maintain Efficiency: Ensure smooth operation and prevent blockages or slowdowns.
Prolong Belt Life: Removing abrasive materials prolongs the lifespan of the conveyor belt.
In some industries, cleanliness and material handling are regulated for health, safety and environmental reasons.
Cost-Effectiveness: They represent a cost-effective solution to maintain the high performance of conveyor systems.

In summary, conveyor scrapers are crucial for the efficient, clean, and safe operation of conveyor systems across various industries. Their ability to remove residual material from belts not only protects the conveyor system but also maintains operational efficiency and safety standards.
