Talking about the Reasons for the Damage of the Conveyor Belt
Currently, the quality of corrugated rib conveyor belts produced in China varies significantly. Many base belts fail to meet the required lateral rigidity standards, while the adhesion between skirts, partitions, and the base belt is often insufficient. Additionally, manufacturers tend to neglect proper maintenance, and equipment users are often unaware of the correct usage and care. As a result, the overall quality of these ribbed conveyor belts is often worse than that of standard belts.
The production process of corrugated rib conveyor belts is highly complex, with each step from the base belt manufacturing to the final assembly playing a critical role. Any mistake at any stage can lead to significant performance issues later on.
The main production steps include:
1. **Base Belt**: Manufacturing the base belt, joining it, and attaching the skirts and partitions.
2. **Skirts**: Producing the skirts and preparing the skirt base for bonding.
3. **Partitions**: Manufacturing the partitions and preparing them for attachment.
4. **Secondary Vulcanization**: Bonding the skirts, partitions, and base strips using heat and pressure.
5. **Maintenance**: Ensuring all components are properly aligned and secured.
6. **Storage**: Storing only qualified products in appropriate conditions.
The secondary vulcanization process is particularly intricate, involving precise glue application, mold selection, and careful handling by workers. Even small errors during this phase can greatly impact the belt’s durability and performance over time.
**Common Vulnerable Parts of Corrugated Conveyor Belts:**
1. **Base Belt**
- **Edge Delamination**: Can occur due to belt misalignment, friction from guide rollers, or poor quality.
- **Non-Working Surface Scratches**: May happen during production, transportation, installation, or use.
2. **Skirts**
- **Skirt Tear**: Often caused by friction from back rollers, especially if there are no double idlers or if the base belt lacks rigidity. A small drum diameter can also contribute.
- **Skirt Base Debonding**: May result from scratches during use, improper drum size, or manufacturing defects.
3. **Partitions**
- **Separator Off**: Usually happens when the return section rubs against the roller, especially without proper idlers. Poor quality is another common cause.
- **Partition Breakage**: Can occur due to tearing from the return roller, again if double idlers are missing or the base belt is not rigid enough.
In conclusion, both the manufacturing process and the usage and maintenance of rib conveyor belts require strict attention and proper procedures. Quality is not solely the responsibility of the manufacturer or the user—it's a shared duty. By improving production standards, ensuring proper maintenance, and raising awareness among users, the performance and lifespan of these belts can be significantly enhanced.
