Buffer Roller Introduction:

Buffer rollers, also known as impact rollers, are specifically designed for use in belt conveyor systems at material receiving points to mitigate the impact of material falling onto the conveyor belt. These rollers play a crucial role in protecting the belt from damage caused by the high impact forces of falling materials, thereby extending the belt's lifespan and ensuring the efficiency of the conveyor system.

Key Functions and Features:

1. Impact Absorption: The primary function of buffer rollers is to absorb and dampen the shock and impact forces that occur when heavy or bulk materials are dropped onto the conveyor belt. This helps prevent damage to the conveyor belt and minimizes spillage.

2. Construction: Buffer rollers typically feature a reinforced structure with a rubber or polyurethane coating on the roller surface. This coating acts as a buffer to cushion the impact and protect the belt and materials.

3. Reduced Material Spillage: By absorbing the impact force, buffer rollers help reduce material spillage and dust generation, improving the overall cleanliness of the conveyor system.

4. Extended Belt Life: The use of buffer rollers can significantly extend the life of the conveyor belt by reducing the wear and tear caused by frequent impacts.

5. Load Support: In addition to absorbing impacts, buffer rollers also provide the necessary support for the conveyor belt and the conveyed load. They help distribute the load evenly across the width of the belt.

6. Various Configurations: Buffer rollers come in different configurations, including troughing impact rollers (for carrying the material) and flat impact rollers (for impact zones with low material heights). They can also be used in combination with standard carrying rollers.

7. Material and Durability: Buffer rollers are made from materials such as steel, rubber, or polyethylene, each offering unique strengths in terms of durability and efficiency. The roller body and seals are often made of polymer materials, which are corrosion-resistant and have good wear resistance and self-lubricating properties, which do not harm the belt.

8. Applications: Buffer rollers are widely used in industries such as mining, coal washing plants, coking plants, and chemical plants, where they are exposed to corrosive environments. They are also used in environmental reclamation projects and agriculture for soil compaction and land leveling.

In summary, buffer rollers are an essential component in conveyor systems, particularly in harsh industrial environments where materials are loaded onto the conveyor belt from a height. Their design and material selection are tailored to provide shock absorption, reduce wear and tear on the conveyor belt, and ensure the reliable operation of the conveyor system
