Self Cleaning Conveyor Belt is a specialized industrial conveyor belt designed to automatically remove residual material from its surface during operation. By leveraging the unique chemical composition of its low-surface-energy cover rubber and/or a specially designed, non-damaging mechanical cleaning system, it addresses industry-wide challenges such as material buildup on the belt surface, dust recirculation, and material carryover during transport. It is widely used in applications involving the conveyance of powders, granules, and wet or sticky materials across industries such as mining, cement and building materials, port bulk cargo, chemicals, food processing, and agriculture.

Advantage of self cleaning conveyor belt

The issue of material "carryover" faced by traditional conveyor belts is not only a source of dust pollution for production lines and surrounding areas but can also lead to material buildup on idlers and drums, causing abnormal belt deviation and excessive wear, which in turn creates long-term operational and maintenance burdens. In recent years, the trend toward deeply integrating intelligent monitoring technology with self-cleaning systems has been accelerating. By using sensors to detect the extent of material buildup on the belt in real time and adaptively controlling cleaning parameters, these systems ensure effective cleaning while minimizing mechanical wear to the greatest extent possible.

Conticlean from Contitech of Continental, with unique rubber formulation, this self cleaning conveyor belt significantly reduces issues such as material carryover and spillage when transporting materials - such as coal and ore with high moisture content - that tend to stick to the belt's cover. This keeps the worksite clean and orderly, prevents the conveyor from drifting off course, and extends the belt's service life.

We offer a wide range of self cleaning conveyor belt, including steel-cord conveyor belts, layered fabric-cord conveyor belts, tubular conveyor belts, and patterned sidewall conveyor belts.

Industries	Typical Materials Handled and On-Site Challenges	Core Technology for Anti-Adhesive Self Clean	Customer Value
Mining (coal, iron, copper, gold, etc.)	Wet coal/coal slurry/iron concentrate/copper concentrate	EPDM/NR Blended Long-Lasting Anti-Sticking Covering Compound	Reduce material buildup and associated waste caused by return-conveyor material, prevent belt misalignment and tearing
Cement quarry Building Materials Plant	Limestone powder/slag powder/wet clay/dried recycled material	Cleaning of Ultra-High Molecular Weight Polyethylene-Coated Rubber Scrapers	Ensure the feeding accuracy of the bucket elevator station and the batching station, as well as the stability of the mixing ratios, to prevent wet, sticky soil from clogging the hoppers during the rainy season.
Ports, terminals, and thermal power plants	Wet coal/coal return/mixed coal types at power plants	Cleaning using a spray system and weather-resistant rubber squeegees	Comply with the strictest environmental protection and explosion-proof regulations to minimize coal spillage and dust dispersion along the conveyor bridge from the grab terminal and material transfer station sections
Tunnel and Water Conservancy Sand, Gravel, and Concrete Batching Plants	High-moisture graded crushed stone, sand, and concrete aggregates during the rainy season	Coated with a wear-resistant ultra-high molecular weight polyester anti-adhesive layer; fully sealed recirculating feed system	Improve the stability of sand and gravel moisture content corrections, reduce material waste, and ensure accurate weighing of raw materials for high-strength concrete
Chemicals and Fertilizers	Fertilizer raw materials/phosphate-potassium compound fertilizers/sulfate minerals	Preferred acid- and alkali-resistant grease-resistant cover rubber, PTFE (polytetrafluoroethylene) anti-adhesive base layer	Designed to address issues such as clumping and sticking to walls caused by moisture in fertilizer storage silos, as well as dust from fine powders like ammonium sulfite, this system significantly reduces corrosion and extends the service life of the conveyor belt.
The optimal configuration of the cleaning system, combined with advanced anti-adhesion technology, significantly reduces friction and physical damage between the cleaner and the belt surface, thereby extending the service life of both the conveyor belt and the entire machine.

FAQ

Q1: Under what circumstances is it necessary or best to use a self-cleaning conveyor belt?

A: When conveying materials that are moist and have high plastic viscosity (such as wet coal, clay, phosphogypsum, dewatered sludge cakes, high-moisture concentrate powder, high-sugar content materials, and fermentation products), and when the material tends to stick to standard surfaces and is gradually dragged back along the return section of the belt, self-cleaning conveyor belts are virtually indispensable. They are not necessarily required for dry bulk materials or applications with minimal back-dragging.

Q2: How long does the anti-adhesion effect last? Why does it perform better than standard conveyor belts?

A: With advances in materials technology, long-lasting, high-performance anti-adhesion belts can extend the effective anti-adhesion period from the original three months to two to three years or more. This duration can be further extended with periodic silicone spraying. Eco-friendly polymers optimize the substrate's polarity and incorporate maleic anhydride-grafted monomers to control the rate of leaching. These polymers chemically cross-link with the reinforcement layer to inhibit migration, significantly delaying the failure of the anti-adhesion layer, whereas standard belts often lose their hydrophobicity much more quickly.

Q3: Will installing a self-cleaning device damage the conveyor belt's cover rubber?

A: Hard metal scrapers can tear the rubber, creating initial damage that leads to cracking and premature failure over time. In contrast, the ContiClean series of custom-fit polyurethane/rubber low-friction scrapers from ContiTech (used in conjunction with tension limit sensors) minimizes wear to a negligible level, leaving the rubber surface virtually unchanged.

Q4: Why does the food industry prefer TPU fully-covered easy-clean belt solutions?

A: The easy-clean belt is manufactured through a one-piece extrusion process with a seamless, integrated edge, resulting in a surface free of any pores or voids. This prevents the growth of pathogenic bacteria or mold. Made from FDA-grade materials with zero migration risk, it even meets the requirements for metal detector inspection on meat processing lines. Cleaning and disinfection times are significantly shorter compared to stainless steel belts.

Q5: Can self-cleaning and corrosion resistance be achieved simultaneously in the high-humidity, high-salt operating environments of ports and docks?

A: Yes. By selecting self-cleaning belts with a moisture-resistant and wear-resistant UPE/PTFE (polytetrafluoroethylene) surface layer and a corrosion-resistant steel-cord core with a halogenated butyl rubber or neoprene formulation in the base compound, these belts can effectively resist corrosion over the long term in high-salt-fog conditions during the loading and unloading of coal, ore, and other dusty materials at coastal facilities, thereby minimizing the risk of environmental fines for dust emissions.
