Product Overview

Acid resistant and alkali resistant conveyor belts are specially designed industrial conveyor belts used for transporting corrosive materials under harsh chemical environments. As a professional chemical resistant conveyor belt manufacturer, we supply high-quality acid resistant conveyor belts and alkali resistant conveyor belts that offer excellent resistance to chemical corrosion, abrasion, and aging. These conveyor belts are widely applied in industries where materials contain acidic or alkaline substances, such as chemical processing, fertilizer production, mining, metallurgy, power plants, and wastewater treatment facilities.

Compared with standard rubber conveyor belts, acid and alkali resistant conveyor belts are manufactured using specially formulated rubber compounds and reinforced carcass structures. This ensures long service life, stable performance, and reduced maintenance costs even when exposed to corrosive materials and aggressive working conditions. With reliable quality and customizable specifications, chemical resistant conveyor belts provide an efficient and cost-effective conveying solution for global industrial users.

What Is an Acid and Alkali Resistant Conveyor Belt

An acid resistant and alkali resistant conveyor belt is a type of rubber conveyor belt engineered to withstand continuous contact with acidic and alkaline materials without degradation. These belts are designed to prevent swelling, cracking, hardening, or loss of strength caused by chemical reactions. By using advanced rubber formulations and optimized structural designs, chemical resistant conveyor belts maintain excellent mechanical properties and flexibility throughout their service life.

Acid resistant conveyor belts are mainly used for conveying materials containing sulfuric acid, phosphoric acid, nitric acid, or other acidic compounds. Alkali resistant conveyor belts are suitable for materials containing lime, soda ash, caustic soda, or other alkaline substances. In many industrial applications, belts are required to resist both acidic and alkaline environments, making chemical resistant conveyor belts a versatile solution.

Structure and Materials

Acid and alkali resistant conveyor belts are composed of three main components: top cover rubber, carcass reinforcement layer, and bottom cover rubber.

The top cover rubber is formulated with high chemical stability to resist acid and alkali corrosion. Depending on application requirements, the rubber compound can also offer abrasion resistance, oil resistance, and moderate heat resistance. The thickness of the top cover is selected based on material abrasiveness and chemical concentration.

The carcass reinforcement layer provides tensile strength and load-bearing capacity. It is commonly made from polyester, nylon, EP fabric, or steel cord for heavy-duty applications. High-quality adhesion between rubber and fabric layers ensures excellent flexibility and resistance to delamination.

The bottom cover rubber protects the belt from friction with conveyor rollers and structural components. It is designed to maintain flexibility and durability while ensuring smooth operation and stable tracking.

Technical Specifications and Parameters

Selecting the correct acid resistant or alkali resistant conveyor belt requires understanding key technical parameters. Common specifications include belt width, belt length, tensile strength, number of plies, cover thickness, and chemical resistance grade.

Belt width typically ranges from 400 mm to over 2000 mm and can be customized according to conveyor design. Tensile strength is available in multiple grades to meet different load requirements, ensuring stable performance in short- or long-distance conveying systems. Cover rubber thickness varies depending on material abrasiveness and chemical exposure level. Chemical resistance grade is selected based on the type and concentration of acids or alkalis being conveyed.

Additional parameters include elongation at break, adhesion strength between plies, operating temperature range, and belt weight. All acid and alkali resistant conveyor belts are manufactured under strict quality control to ensure consistent performance and compliance with industrial standards.

Types of Chemical Resistant Conveyor Belts

Chemical resistant conveyor belts can be classified into several types based on application and working conditions. Acid resistant conveyor belts are designed for acidic materials commonly found in fertilizer plants, chemical processing facilities, and mining operations. Alkali resistant conveyor belts are suitable for handling lime, alkaline powders, and chemical residues. General chemical resistant conveyor belts offer balanced resistance to both acids and alkalis and are widely used in mixed-material environments.

Some chemical resistant conveyor belts can also be combined with other properties, such as oil resistance or flame retardancy, to meet complex industrial requirements. Patterned chemical resistant conveyor belts are available for inclined conveying applications where anti-slip performance is required.

Applications of Acid and Alkali Resistant Conveyor Belts

Acid and alkali resistant conveyor belts are widely used in industries where materials are corrosive or chemically active. In the chemical industry, they are used to transport raw materials, intermediates, and finished chemical products. Fertilizer plants rely on acid resistant conveyor belts for conveying phosphates, sulfur-based materials, and chemical powders.

In mining and metallurgy, chemical resistant conveyor belts handle ores and tailings containing acidic or alkaline substances. Power plants use these belts for ash handling and waste material transportation. Environmental protection and wastewater treatment facilities apply chemical resistant conveyor belts for sludge and chemical residue conveying. Their versatility makes them suitable for both indoor and outdoor applications.

Performance Advantages

The primary advantage of acid and alkali resistant conveyor belts is their excellent chemical resistance, which significantly extends service life in corrosive environments. These belts maintain stable physical properties, preventing premature failure and reducing downtime. High abrasion resistance ensures durability when conveying sharp or abrasive materials.

Chemical resistant conveyor belts also offer good flexibility, allowing smooth operation over rollers and pulleys. Their strong carcass structure ensures reliable load-bearing capacity and resistance to impact. With proper selection and maintenance, these conveyor belts deliver consistent performance and cost-effective operation.

Installation Guidelines

Proper installation is essential for ensuring optimal performance of acid and alkali resistant conveyor belts. Before installation, the conveyor system should be inspected to ensure rollers, pulleys, and frames are aligned and free from sharp edges. Belt tension should be adjusted according to manufacturer recommendations to prevent slippage or excessive stress.

During installation, the belt should be carefully positioned to avoid twisting or uneven tension. After installation, the conveyor should be operated without load for a trial period to check tracking and alignment. Any deviation should be corrected immediately to prevent uneven wear.

Usage Instructions

During operation, chemical resistant conveyor belts should be loaded evenly to avoid localized stress and material spillage. The belt speed should match the material flow rate and conveyor design. Avoid conveying materials beyond the belt’s chemical resistance or temperature limits.

Regular inspection during operation helps identify early signs of wear, corrosion, or damage. Proper cleaning prevents chemical residue buildup, which can affect belt performance and service life.

Maintenance and Service Life

Routine maintenance is crucial for extending the service life of acid and alkali resistant conveyor belts. Regular cleaning removes corrosive residues and prevents chemical accumulation. Belt cleaners and scrapers should be adjusted correctly to avoid excessive wear.

Periodic inspection of belt splices, joints, and edges is recommended. Conveyor components such as rollers and pulleys should be maintained to ensure smooth belt movement. With proper maintenance, chemical resistant conveyor belts can operate reliably for many years even in harsh environments.
