Durable Conveyor Belt Solution for Oily and Greasy Material Handling

Product Overview

Oil resistant conveyor belts are specially designed rubber conveyor belts engineered to transport materials containing oils, fats, greases, and other petroleum-based substances. In many industrial environments, conveyed materials release oil during handling, processing, or transportation. These oils can penetrate standard rubber belts, causing swelling, softening, cracking, and rapid loss of tensile strength. Oil resistant conveyor belts are developed to overcome these challenges by using advanced oil-resistant rubber compounds that maintain structural stability and mechanical performance even under prolonged oil exposure.

Widely applied in industries such as mining, recycling, food processing, agriculture, ports, metallurgy, cement plants, and waste treatment facilities, oil resistant conveyor belts ensure safe, stable, and efficient material transportation. By significantly extending belt service life and reducing maintenance frequency, they provide an economical and reliable solution for oil-related conveying applications.

What Is an Oil Resistant Conveyor Belt

An oil resistant conveyor belt is a type of industrial rubber conveyor belt designed to resist degradation caused by contact with oil-based materials. Oils can cause conventional rubber compounds to expand, lose elasticity, and break down at the molecular level. Oil resistant conveyor belts use specially formulated rubber covers that prevent oil absorption and chemical reaction, ensuring consistent performance throughout the belt’s lifespan.

These belts are particularly suitable for conveying materials such as oily ores, coal with oil additives, recycled waste, oily metal scraps, grain with vegetable oils, and industrial by-products containing lubricants or petroleum residues.

Belt Structure and Material Composition

Oil resistant conveyor belts consist of three essential components: top cover rubber, carcass reinforcement layer, and bottom cover rubber.

Top Cover Rubber

The top cover is made from oil-resistant rubber compounds designed to limit oil penetration and prevent swelling. Depending on the oil type and concentration, different rubber formulations can be selected to ensure optimal resistance. The surface maintains abrasion resistance, flexibility, and chemical stability even in continuous oily environments.

Carcass Reinforcement Layer

The carcass provides tensile strength and load-bearing capacity. Common reinforcement materials include polyester fabric, nylon fabric, EP fabric, and steel cords for heavy-duty applications. High adhesion strength between rubber and fabric ensures excellent resistance to delamination and impact damage.

Bottom Cover Rubber

The bottom cover protects the carcass from wear caused by conveyor rollers and pulleys. It is designed for flexibility, low friction, and long-term durability to ensure smooth belt operation and proper tracking.

Oil Resistance Grades and Classification

Oil resistant conveyor belts are generally classified based on oil resistance performance and oil type exposure.

  • Moderate Oil Resistant Conveyor Belts
    Suitable for materials containing small amounts of animal oil, vegetable oil, or mild industrial lubricants.

  • High Oil Resistant Conveyor Belts
    Designed for continuous exposure to petroleum-based oils, heavy greases, and industrial lubricants.

  • Special Oil Resistant Conveyor Belts
    Customized solutions for extreme oil environments, often combined with abrasion resistance or heat resistance.

Selecting the appropriate oil resistance grade ensures optimal performance and prevents premature belt failure.

Technical Parameters and Specifications

Oil resistant conveyor belts can be manufactured in a wide range of specifications to meet various conveying requirements.

Typical parameters include belt width, length, tensile strength, number of plies, and cover thickness. Belt widths commonly range from 400 mm to 2400 mm, while tensile strength varies depending on application load. Cover thickness is selected based on material abrasiveness, oil concentration, and impact conditions.

Additional technical parameters include elongation at break, adhesion strength, belt weight, operating temperature range, and oil resistance performance level. All belts are produced under strict quality control systems to ensure consistent quality and reliability.

Performance Advantages

Oil resistant conveyor belts offer several significant advantages over standard rubber conveyor belts.

The most important benefit is excellent resistance to oil penetration, which prevents swelling, softening, and cracking of the rubber surface. This maintains belt flexibility and tensile strength throughout long-term use. High abrasion resistance ensures durability when handling rough or sharp materials.

These belts also provide stable tracking performance and strong impact resistance. By reducing belt damage and downtime, oil resistant conveyor belts help improve production efficiency and reduce overall operating costs.

Application Scenarios

Oil resistant conveyor belts are widely used across multiple industries.

In mining and mineral processing, they convey ores and coal containing oil residues or lubricants. Recycling facilities rely on oil resistant conveyor belts to handle waste materials contaminated with oils and greases. In agriculture and food processing, these belts transport grains, seeds, and by-products containing vegetable oils.

Ports and logistics centers use oil resistant conveyor belts for bulk material handling, while cement plants and steel mills apply them in environments where oil contamination is common. Their adaptability makes them suitable for both indoor and outdoor conveying systems.

Environmental and Operating Conditions

Oil resistant conveyor belts are designed to operate in a wide range of environmental conditions. They can withstand moderate temperature variations, humidity, dust, and outdoor exposure. For high-temperature oily materials, special oil and heat resistant conveyor belts can be selected.

Proper belt selection based on operating environment ensures stable performance and extended service life.

Installation Guidelines

Correct installation is critical for oil resistant conveyor belt performance. Before installation, conveyor system components such as rollers, pulleys, and frames should be inspected and cleaned. Any oil accumulation on rollers should be removed to prevent slippage.

During installation, belt tension should be adjusted evenly according to manufacturer recommendations. After installation, a trial run without load is recommended to check belt tracking and system alignment.

Operating Instructions

During operation, materials should be loaded evenly across the belt width to prevent uneven wear. Sudden overloads should be avoided, as they may damage the belt carcass. Operators should ensure that the belt is used within its oil resistance and temperature limits.

Regular observation during operation helps detect abnormal conditions early and prevents unexpected downtime.

Maintenance and Cleaning

Routine maintenance significantly extends the service life of oil resistant conveyor belts. Regular cleaning removes oil residues and debris from the belt surface. Properly designed belt cleaners and scrapers help maintain cleanliness without damaging the rubber cover.

Periodic inspection of splices, joints, and belt edges is recommended. Conveyor rollers and pulleys should be maintained to ensure smooth belt movement and correct alignment.

Common Problems and Solutions

Belt Swelling
Occurs when the belt is exposed to oil beyond its resistance grade. Selecting a higher oil resistance grade resolves this issue.

Belt Slippage
Often caused by oil accumulation on pulleys or insufficient tension. Cleaning and proper tension adjustment are effective solutions.

Surface Wear
May result from abrasive materials combined with oil exposure. A thicker cover or abrasion-resistant oil resistant belt is recommended.

How to Choose the Right Oil Resistant Conveyor Belt

Choosing the correct oil resistant conveyor belt requires evaluating the type of oil, oil concentration, conveyed material properties, load capacity, conveying distance, and operating environment. Consulting with an experienced conveyor belt manufacturer ensures the most suitable solution for your application.

Quality Control and Manufacturing Process

Oil resistant conveyor belts are manufactured using advanced production equipment and strict quality control procedures. Raw materials are carefully selected to ensure consistent oil resistance performance. Each belt undergoes testing for tensile strength, adhesion, and oil resistance before delivery.
