Industrial Internal & External Scraper For Belt Conveyor Supplier

Belt Cleaner

A belt cleaner is an essential device used to maintain the cleanliness and performance of conveyor belt systems. Installed at strategic points—typically at the head pulley—it effectively removes material buildup, debris, and residue from the belt surface, helping to prevent carryback and improve operational efficiency.

Belt cleaners come in various designs, including primary cleaners, secondary cleaners, and rotary brush cleaners, each serving specific cleaning needs. Primary cleaners remove the bulk of material immediately after discharge, while secondary cleaners provide a more precise cleaning result. Rotary brush cleaners are ideal for fine particles and sticky materials.

Constructed from durable materials such as polyurethane, stainless steel, and tungsten carbide, belt cleaners are built to withstand harsh industrial environments, from mining and cement to food processing and packaging industries.By maintaining a clean belt, these devices reduce downtime, minimize belt wear, and extend the life of both the conveyor and its components. They also help prevent product contamination and support safer, more hygienic operations.Easy to install and maintain, a quality belt cleaner is a smart investment for any conveyor system, improving productivity while reducing maintenance costs over time.

How Do You Clean A Conveyor Belt?

Cleaning a conveyor belt is essential to maintain hygiene, ensure efficient operation, and extend its service life. The method of cleaning depends on the type of material being conveyed, the industry, and the type of conveyor belt.

For dry debris and dust, a simple brush or vacuum cleaner can be used to remove particles from the surface. For food-grade or sanitary belts, regular cleaning with water and approved detergents is necessary. High-pressure water jets and steam cleaners are commonly used in the food, pharmaceutical, and beverage industries. These methods effectively remove residue and bacteria without damaging the belt surface.

In industrial settings, mechanical belt cleaners such as scrapers or rotary brushes may be installed to continuously remove debris during operation. In some cases, belt washing systems are integrated into the conveyor design to ensure automatic and consistent cleaning.

Before any cleaning procedure, the conveyor must be turned off and locked out to ensure worker safety. Belts should be visually inspected for buildup, wear, or damage. Cleaning frequency should match the operational needs, ranging from daily to weekly maintenance schedules.

For stubborn stains or grease, specialized degreasers or solvents may be used, but care must be taken to avoid chemicals that could degrade the belt material.

Proper cleaning not only prevents contamination and ensures product quality but also reduces the risk of belt slippage and equipment malfunction. By implementing a consistent and effective cleaning routine, companies can reduce downtime, improve efficiency, and comply with industry hygiene standards.

Which Device Is Used For Cleaning The Conveyor Belt?

Several devices are specifically designed to clean conveyor belts and maintain optimal performance. The most commonly used device is the belt cleaner, also known as a belt scraper. This tool is installed at various points along the conveyor system to remove debris, residue, or product buildup from the belt surface during or after operation.

Primary belt cleaners are typically mounted at the head pulley and are designed to remove the bulk of material stuck to the belt. Made from durable materials such as polyurethane or tungsten carbide, they effectively scrape off sticky or wet substances without damaging the belt.

Secondary belt cleaners, placed after the primary cleaner, provide additional cleaning for fine residue or stubborn material. These are often used in combination with the primary scraper for a more thorough result.

Rotary brush cleaners are another common solution, especially for belts carrying fine powders or sticky materials. These motor-driven brushes scrub the belt surface and are ideal for flat or modular belt designs.

In industries that require strict hygiene, such as food or pharmaceuticals, belt washing systems are used. These systems integrate spray bars, scrubbing rollers, and vacuum units to clean and dry the belt automatically.

Air knives or air jets may also be used to blow off loose particles, especially in dry or dusty applications.

Choosing the right conveyor belt cleaning device depends on factors like belt type, material conveyed, environmental conditions, and hygiene requirements. Proper cleaning extends the belt’s service life, ensures smooth operation, and reduces downtime caused by contamination or mechanical issues.
