Belt conveyor systems are the backbone of material handling in industries such as mining, agriculture, and manufacturing. A critical component of these systems is the Belt Cleaning Systems, which ensure efficient operation by removing residual material from conveyor belts. Among these systems, Primary and Secondary Belt Cleaners play distinct yet complementary roles. Understanding their differences is essential for optimizing conveyor performance, reducing maintenance costs, and extending belt life.
In this article, we delve into the technical and functional disparities between primary and secondary cleaners, explore their applications, and highlight the advantages of modern solutions like the Hanpeng HP-H1 Secondary Belt Cleaner. With a focus on innovation and durability, this article also aligns with the latest industry trends, emphasizing efficiency, sustainability, and adaptability.
Belt Cleaning Systems are engineered to address the persistent challenge of material carryback—residual particles that adhere to conveyor belts after discharge. Left unchecked, carryback causes:
Belt misalignment
Increased wear and tear
Safety hazards (e.g., slippage, material buildup)
Higher operational costs due to frequent maintenance
To mitigate these issues, Primary and Secondary Belt Cleaners work in tandem. Let’s break down their roles.
A Primary Belt Cleaner is installed at the conveyor’s head pulley, where the bulk of material is discharged. Its primary function is to remove large quantities of residual material immediately after the discharge point. Key features include:
Blade Material: Often polyurethane or tungsten carbide for durability.
Installation Angle: Positioned to scrape against the belt’s direction.
Pressure Adjustment: Ensures optimal contact without damaging the belt.
Primary cleaners excel in high-volume, coarse-material environments, such as mining or aggregate processing. However, they are less effective against fine or sticky residues, which necessitates the use of a Secondary Belt Cleaner.
The Secondary Belt Cleaner is typically installed further along the return strand of the conveyor, addressing finer particles that evade the primary cleaner. Its design focuses on precision and adaptability:
Blade Flexibility: Adjustable blades conform to belt imperfections.
Material-Specific Solutions: Tailored for sticky, wet, or abrasive residues.
Enhanced Durability: Built to withstand harsh conditions like high-speed wear and impact.
| Feature | Primary Cleaner | Secondary Belt Cleaner |
|---|---|---|
| Installation Location | Head pulley | Return strand (post-primary cleaner) |
| Target Material | Bulk, coarse residues | Fine, sticky, or adhesive residues |
| Blade Pressure | High pressure | Moderate to low pressure |
| Material Compatibility | General-purpose | Specialized (e.g., coal slurry, peat) |
With industries increasingly handling adhesive or moisture-laden materials (e.g., coal slurry, peat), Secondary Belt Cleaners have evolved to address unique challenges:
Adaptability to Harsh Conditions: Modern secondary cleaners, like the Hanpeng HP-H1, are engineered for extreme environments, including high-speed belts (up to 10m/s) and temperatures ranging from -40°C to 120°C.
Enhanced Cleaning Efficiency: Advanced blade designs and materials reduce carryback by over 90%, minimizing downtime.
Sustainability: By reducing material waste and energy consumption, secondary cleaners align with global sustainability goals.
Hanpeng’s HP-H1 Secondary Belt Cleaner exemplifies cutting-edge engineering tailored for diverse industrial needs. Below, we explore its standout features and applications.
The HP-H1 is versatile, making it ideal for:
General to Extreme Conditions:
Water-saturated environments.
Strong adhesive materials (coal slurry, peat).
High-speed wear (up to 10m/s) and impact-prone settings.
Functionality as a Primary Cleaner in bidirectional operations.
Bandwidth Compatibility: 600–2400mm (see table below).
Temperature Resilience: Effective in cold or hot vulcanized joint conveyor belts.
Each blade can be adjusted vertically to maintain optimal contact with the belt, ensuring consistent cleaning performance even as the belt wears.
The blades are crafted from tungsten carbide alloy, offering exceptional wear resistance and a lifespan up to 3x longer than conventional materials.
Every blade is supported by an independent high elastic rubber module, providing localized impact resistance and reducing stress on the blade structure.
A patented double buffer elastic compensation device allows the holder to rebound instantly after impact, enhancing overall durability in high-vibration environments.
The split main and auxiliary support structure simplifies installation. Tension is easily adjusted via support seat screws, ensuring a perfect blade-to-belt fit.
A smooth PE fender prevents material buildup around the cleaner, reducing corrosion risk and maintaining scraping efficiency.
The demand for Secondary Belt Cleaners is surging due to:
Automation: Integration with IoT for real-time pressure and wear monitoring.
Material Innovation: Development of hybrid blades for multi-condition use.
Sustainability: Cleaners that reduce energy use by minimizing belt friction.
Hanpeng’s HP-H1 addresses these trends through modularity, durability, and adaptability, making it a future-proof investment.
