Conveyor Belt Scraper Types in Conveyor Scrapers

Primary Conveyor Belt Scraper

The primary conveyor belt scraper is a critical component of conveyor scrapers, designed for aggressive cleaning action right at the point where material is discharged from the conveyor belt. Positioned at the head pulley, the primary scraper is the first line of defense against material carryback. Its main function is to remove the bulk of the material that sticks to the belt, ensuring that the conveyor system operates efficiently and without interruption.

The design of primary conveyor belt scrapers typically involves durable blades made from materials like polyurethane or carbide. These blades are engineered to withstand the abrasive nature of bulk materials commonly transported in industries such as mining, cement, and aggregate. For example, the Martin Engineering Primary Belt Cleaner is known for its robust construction and high efficiency in removing carryback. It features a heavy-duty blade that can endure the harsh conditions of industrial applications, thereby reducing maintenance needs and prolonging the lifespan of the conveyor belt.

Primary scrapers are also adjustable to maintain optimal tension against the belt, ensuring consistent cleaning performance. This adjustability is crucial for accommodating wear on the scraper blade over time, maintaining effective cleaning without damaging the belt. Companies like Flexco provide primary scrapers with easy-to-adjust tensioning systems that enhance their operational efficiency and longevity.

Secondary Belt Scraper

Secondary belt scrapers are an essential part of conveyor scrapers, positioned further down the conveyor system, typically after the head pulley. Their primary role is to remove any remaining material that was not cleared by the primary scraper. Secondary scrapers are generally designed to be less aggressive than primary scrapers, using lighter blades to ensure thorough cleaning without causing excessive wear to the conveyor belt.

The function of secondary belt scrapers is to provide a finishing touch to the cleaning process, ensuring that the conveyor belt is as clean as possible before it returns to the loading point. For instance, the Flexco Secondary Belt Cleaner is renowned for its precision cleaning capabilities. It employs a variety of blade materials, including polyurethane and carbide, to suit different applications and material types. The use of secondary scrapers is particularly important in environments where even small amounts of carryback can cause significant problems, such as in food processing or chemical manufacturing.

One of the key features of secondary scrapers is their ability to self-adjust to the belt’s surface, ensuring consistent contact and cleaning performance. This self-adjusting mechanism helps maintain effective cleaning throughout the scraper’s lifespan, reducing the need for frequent manual adjustments and maintenance.

Specialty Scrapers

In addition to primary and secondary scrapers, there are various specialty scrapers designed to address specific cleaning challenges and environments. These specialty conveyor scrapers are tailored to meet the unique requirements of particular industries or materials, ensuring optimal cleaning performance in even the most challenging conditions.

Belt cleaners mitigate this issue by scraping off the residual materials, thereby keeping the belts clean and functional. Companies such as Flexco and Martin Engineering specialize in producing high-quality belt cleaners that are designed to handle the rigorous demands of these industries.

Types of Belt Cleaners

There are various types of belt cleaners used in conveyor scrapers, each designed for specific functions and cleaning needs. The two main categories are primary and secondary belt cleaners.

Primary Belt Cleaners

Primary belt cleaners are positioned at the head pulley of the conveyor system. Their main function is to remove the bulk of the material that adheres to the belt after the discharge point. These cleaners are typically more aggressive, using sturdy blades made from materials like polyurethane or carbide to effectively scrape off the material. For example, Flexco’s EZP1 Precleaner is designed for primary cleaning and is known for its robust construction and high efficiency in removing large amounts of carryback material.

Secondary Belt Cleaners

Secondary belt cleaners are installed further down the conveyor line, typically beyond the head pulley. Their role is to remove any remaining material that was not cleared by the primary cleaner. Secondary cleaners are generally less aggressive and use lighter blades to ensure thorough cleaning without damaging the belt. Martin Engineering’s SQC2 Secondary Cleaner is a popular choice for secondary cleaning, offering precision cleaning and easy maintenance, which enhances the overall efficiency of the conveyor system.

Benefits of Belt Cleaners

The use of belt cleaners in conveyor scrapers provides numerous benefits that significantly enhance the performance and longevity of conveyor systems.

Reduced Material Carryback

One of the primary benefits of using belt cleaners is the substantial reduction in material carryback. Carryback refers to the residual material that remains on the conveyor belt after it has discharged its load. This material can accumulate over time, leading to belt misalignment, increased wear, and potential damage to the conveyor system. By effectively removing carryback, belt cleaners help maintain a clean belt surface, ensuring smooth and efficient operation.

Lower Maintenance Costs

Another significant advantage of using belt cleaners is the reduction in maintenance costs. Clean conveyor belts experience less wear and tear, which translates to fewer repairs and replacements. For example, a study conducted by West River Conveyors showed that the implementation of high-quality belt cleaners reduced maintenance costs by up to 20%, as the belts required less frequent servicing and had a longer operational lifespan.

Improved Conveyor Belt Lifespan

The lifespan of a conveyor belt is directly impacted by the presence of residual material. Accumulated material can cause abrasive wear on the belt surface, leading to premature aging and frequent replacements. Belt cleaners, as part of conveyor scrapers, help extend the lifespan of the belt by maintaining a clean surface, reducing friction, and minimizing wear. This not only enhances the durability of the belt but also ensures consistent performance over time.

Real-World Applications and Examples

The benefits of belt cleaners in conveyor scrapers are evident in various real-world applications. In the mining industry, for example, conveyor belts are used to transport large quantities of ore and other materials. The harsh conditions and abrasive nature of these materials make belt cleaners essential for maintaining the efficiency and reliability of the conveyor systems. Companies like Flexco and Martin Engineering have developed specialized belt cleaners that can withstand the demanding conditions of mining operations, providing effective cleaning and reducing downtime.

Similarly, in the food processing industry, hygiene and cleanliness are of utmost importance.
