Acid Alkali Conveyor Belt

Qingdao Best Friend Rubber & Plastic Co., Ltd. is one of the most reliable manufacturers and suppliers of acid alkali conveyor belt in China, also supports customized service. If you're going to buy high quality acid alkali conveyor belt made in China, welcome to get more information from our factory.

 

Acid Alkali Conveyor Belt is specially engineered for conveying materials exposed to acidic, alkaline, and chemically aggressive environments. Unlike standard rubber conveyor belts that may suffer from swelling, cracking, and performance degradation, this belt uses specially formulated rubber compounds to provide enhanced resistance against chemical corrosion.

It is designed for industries where conveyor reliability is critical, helping reduce unexpected downtime, frequent belt replacement, and maintenance costs caused by chemical exposure.

1. Reinforcement Properties

Made of high-tensile steel cords and various cover grades (see below). A typical carcass with 7 x 7 hot-galvanised steel cords provides a tensile strength of up to 2,000 N/mm. Also available as 7 x 19 for higher tensile strength (10 000 N/mm). Standard cords have an elongation of 0.22 - 0.28%. High structural strength and pull-out strength ensure good resistance against fatigue. The open cross-lay design of the cords and the chemical adhesive system ensure that the core rubber penetrates thoroughly, bonds well and protects against corrosion for long-term integrity.

 

2. Cover Grades

The belts come with various cover grades, all made of high-quality rubber with extremely high resistance to abrasion, cutting and impact and with excellent ageing properties. The choice of cover grade will depend on the application and will also determine the working life of the belt. Matching the right belt to your application means generating less waste in the long run - helping you to reach your sustainability targets.

 

3. Wear-resistant

Available in X, Y, W grades (and similar) for heavy-wear conveying applications such as bulky, sharp materials like heavy, abrasive rocks. High-quality cover grades are recommended to offer the best protection to the belt carcass.

 

4. Heat-resistant

Different types of grades are available for high-temperature applications (T120 and T200) such as clinker, coke, foundry sand and slag. Can be used for transporting material at continuous temperatures of up to 190 °C, with peaks of up to 200 °C.

 

5. Flame-resistant

Available in flame-resistant grade K to comply with ISO 340. Can be used in tunnel projects but not underground applications.

 

 

In fertilizer plants, corrosive materials such as ammonium phosphate and potassium fertilizer can accelerate rubber degradation. Acid Alkali Conveyor Belt provides chemical-resistant performance to maintain stable conveying and reduce replacement frequency.

 

Chemical Raw Material Handling

Typical materials include: Acid-containing powders,Alkali compounds,Chemical additives,Industrial salts

During continuous operation, these materials may accelerate rubber aging and cause conventional conveyor belts to crack or lose strength.

Our Acid Alkali Conveyor Belt uses specially formulated rubber compounds to provide improved resistance against chemical attack, helping maintain stable conveying performance and reduce unexpected downtime.

 

Fertilizer Production Lines

Typical materials include: Ammonium phosphate,Potassium fertilizer,Compound fertilizer

Acid Alkali Conveyor Belt provides:

✔ Chemical resistance
✔ Stable mechanical strength
✔ Reduced maintenance frequency

 

Mineral Processing Applications

Mineral processing operations often involve chemical treatment processes such as flotation and acid leaching, where conveyor belts may contact chemically active materials and moisture.

Acid Alkali Conveyor Belt is suitable for transporting mineral concentrates, treated ores, and processing residues. Its chemical-resistant rubber cover helps protect the belt structure from degradation, providing reliable performance in demanding mining environments.

Suitable for: Mining plants, mineral recovery systems, and ore processing facilities.

 

Industrial Waste Treatment

Industrial waste treatment systems often require conveyor belts to handle materials containing chemical residues, moisture, and abrasive particles.

Standard belts may experience accelerated aging and surface damage under these harsh conditions. Acid Alkali Conveyor Belt provides improved corrosion resistance and durability, helping waste processing facilities achieve more reliable material handling with lower maintenance requirements.

Suitable for: Waste treatment plants, recycling facilities, and industrial disposal systems.
