Core Advantages of Industrial Conveyor Belt Cleaning System

Primary Conveyor Belt Cleaner (H-Type Head Scraper)

The primary belt cleaner is installed at the head drive pulley, serving as the first-stage heavy cleaning procedure. Equipped with thickened wear-resistant blades, it removes approximately 70% of bulk ore, hardened cement clinker, heavy slag and thick attachments on the belt surface. Featuring an adaptive automatic spring tension structure, this heavy-duty belt scraper maintains consistent blade contact with the belt surface without causing belt damage. It is highly suitable for high-capacity and continuous conveying lines in mines and cement plants.

Secondary Conveyor Belt Cleaner (P-Type Fine Scraper)

Installed at the tangent position behind the head pulley, the secondary belt cleaner focuses on fine residual materials that primary cleaners cannot remove. It thoroughly cleans fine powder, sticky slurry and tiny hardened particles left on belts after conveying cement clinker, wet aggregate and adhesive minerals, achieving an overall cleaning efficiency of over 90%. Adopting segmented high-elastic PU blades, this belt scraper operates smoothly with low noise, excellent fitting performance and aging resistance, making it an essential accessory for sticky material conveying lines.

V-Plough Return Belt Cleaner

The V-plough belt cleaner is specially designed for the non-working surface of return conveyor belts. It effectively removes floating dust, loose gravel and fallen debris attached to the inner belt side. With a unique V-shaped diversion structure, the equipment guides foreign materials toward both sides of the belt, preventing impurities from entering return idlers. It avoids common faults such as idler jamming, belt scratching, conveyor deviation and abnormal wear, acting as a necessary protective component for long-distance mining and aggregate conveying systems.

Spring & Pneumatic Tension Belt Cleaner

Our industrial belt cleaning equipment comes with two premium tension structures: automatic spring tension and precise pneumatic tension. The spring tension design realizes dynamic elastic compensation, adapting to belt vibration and slight wear to maintain continuous blade fitting without frequent manual adjustment. The pneumatic tension model is tailored for large-scale high-speed belt conveyors, supporting accurate pressure regulation to adapt to high-load, wide-belt and high-speed operating scenarios, ensuring long-term uniform and stable cleaning performance.

Polyurethane PU Belt Scraper

The polyurethane belt scraper is the most versatile and widely adopted cleaning equipment for industrial conveyor systems. Manufactured with high-elastic and wear-resistant PU material, it features low friction, strong toughness and outstanding anti-aging performance. The flexible blade fits tightly on belt surfaces without scratching rubber covers or damaging belt splice joints. Ideal for dry bulk materials, fine dust and slightly sticky materials, the PU conveyor belt cleaner has become the standard configuration for cement plants, sand yards and quarries with reliable performance and cost-effectiveness.

What is a belt cleaner?

A belt cleaner, also widely referred to as a conveyor belt cleaner or belt scraper, is a vital industrial accessory for heavy-duty belt conveyor systems. It is specially designed to remove material carryback, sticky residues, fine dust, bulk debris and leftover materials from rubber conveyor belt surfaces. A complete conveyor belt cleaning system generally includes primary belt scrapers and secondary conveyor belt cleaners, equipped with wear-resistant blades and automatic tension devices. It effectively reduces conveyor belt wear, idler damage, material spillage and unexpected downtime, ensuring stable and efficient operation for mining, cement plant and quarry bulk material conveying lines.

Do primary and secondary belt cleaners have to be used together?

It is not mandatory to use them in combination. For dry sand, ordinary stone and low-viscosity materials, a single primary head cleaner can meet basic cleaning demands. However, for high-viscosity materials such as cement clinker, wet aggregate and mineral powder, a combined primary and secondary cleaning configuration is highly recommended. It removes thick surface materials and tiny residual powder thoroughly, raising cleaning efficiency above 90% and eliminating material carryback fundamentally.

Will polyurethane scraper blades damage rubber conveyor belts?

Our high-elastic segmented polyurethane blades feature flexible fitting and low friction, which will never scratch belt surfaces or wear vulcanized belt splices. For belts with mechanical metal buckles, hard tungsten carbide and ceramic blades are forbidden to avoid structural collision and belt surface damage.

Can V-plough cleaners be used on bidirectional running belt conveyors?

Standard V-plough cleaners are only applicable to single-direction conveyor belts, serving as cost-effective return cleaning solutions. For special bidirectional reversible belt conveyors, ordinary V-plough structures cannot adapt to forward and reverse operation. Custom symmetrical bidirectional cleaning devices are required to ensure stable cleaning without jamming or material accumulation in both operating directions.

Which belt cleaner is most durable for high-temperature cement clinker conveying?

For cement clinker and hot mineral materials above 70℃, ordinary PU blades are prone to high-temperature aging, cracking and elasticity loss, leading to cleaning failure. We recommend the combined configuration of tungsten carbide primary cleaner and high-temperature resistant modified PU secondary cleaner. Carbide blades resist high-temperature scouring, while upgraded PU blades prevent thermal aging, adapting to long-term continuous high-temperature operation of cement production lines.

What is the regular replacement cycle of conveyor belt cleaner blades?

The service life depends on material abrasiveness, viscosity and daily operating hours. Under normal room-temperature conditions for limestone and sand conveying, PU blades can serve 6 to 12 months. For high-abrasion mining scenarios, the service life will be slightly shortened. Tungsten carbide and ceramic hard blades deliver excellent wear resistance, with a stable service life of 2 to 3 years under normal working conditions, greatly reducing maintenance frequency.

Will belt vibration and slight deviation affect cleaning performance?

Ordinary fixed cleaners easily generate cleaning dead angles and poor fitting due to belt vibration and slight deviation. All DARKO conveyor belt cleaners are equipped with automatic tension compensation structures. Both spring and pneumatic models adapt to belt vibration, slight deviation and natural wear, maintaining tight blade fitting continuously to ensure stable and consistent cleaning results without frequent manual adjustment.

Are there special requirements for belt cleaners in underground coal mines?

Underground coal mines belong to high-risk explosion-proof and dust-control working scenarios with strict standards for flame retardancy and static resistance. DARKO provides customized flame-retardant and anti-static belt cleaners that fully comply with underground safety specifications. Featuring excellent dust suppression performance and anti-static properties, these customized products support safe operation of all underground conveyor equipment.

How to select belt cleaners for worn old conveyor belts?

Severely worn and uneven old belts are not suitable for high-hardness alloy or ceramic blades, which will accelerate belt damage and scrapping. It is recommended to adopt high-elastic flexible PU blades with adjustable compression structures. The flexible fitting design ensures basic cleaning effects while protecting worn belt surfaces and delaying equipment scrapping.
