**Comparison Between Rubberized Rollers, Anti-Slip Rubber Rollers, and Cast Rubber: How to Handle New Rubber Rollers and Avoid Premature Wear**
When comparing rubberized rollers, anti-slip rubber rollers, standard rubber rollers, and cast rubber, it's essential to understand the differences in their performance, durability, and application. Improper use or incorrect handling of newly manufactured rubber rollers can significantly reduce their lifespan. Traditional hot vulcanized rubber drums often suffer from low sulfur pressure, high sulfur content, and poor wear resistance, leading to aging and reduced adhesion to conveyor belts, which affects cleaning efficiency.
To address these issues, advanced roller lagging technology has been introduced, bringing in German innovations. This method uses high-quality materials such as wear-resistant non-slip rubber sheets, flame-retardant anti-static rubber sheets, and imported super-abrasive rubber sheets. The process involves selecting the appropriate adhesive and using a special cold-bonding technique to ensure long-term stability and performance.
**Key Features of Modern Roller Lagging:**
1. Dense material with excellent elasticity and high friction coefficient.
2. Superior wear resistance and strong tensile and tear strength.
3. Customizable for different drum sizes and technical requirements.
4. Can be patterned (e.g., diamond or chevron) to enhance surface friction, reduce belt slippage, and improve overall efficiency.
**Roller Covering vs. Cast Rubber Covering: Process Differences**
Currently, two main methods are used for roller covering: cold bonding and hot vulcanization.
- **Hot Vulcanization Process:**
The drum is completely disassembled, and the cylinder is machined to create grooves. Two layers of adhesive (metal and rubber) are applied, followed by pressing raw rubber onto the drum. It is then vulcanized at 180°C in a steam chamber. Afterward, the drum is reassembled.
- **Cold Encapsulation Process:**
The drum is cleaned, and a special adhesive is applied before the rubber sheet is directly bonded to the surface. This method does not require full disassembly, making it more efficient.
**Comparison Between Cold Vulcanization and Traditional Methods:**
- **Cold Vulcanization:**
- Adhesion force with metal drum: ~12 N/mm
- Vulcanization pressure: 50 kg/cm²
- High rubber density, excellent wear resistance, longer service life (several times that of traditional methods)
- High friction coefficient, reduces belt stress, good elasticity, and anti-adhesion properties
- **Traditional Method:**
- Adhesion force: 3–10 N/mm
- Vulcanization pressure: 6–8 kg/cm²
- Lower rubber density, poorer wear resistance, shorter lifespan
- Weaker adhesion to belt, increased tensile stress, faster aging, and potential material sticking
**How to Handle Newly Manufactured Rubber Rollers?**
After manufacturing, the internal structure of new rubber rollers may not be fully stabilized. Using them immediately can lead to premature failure. It's recommended to let the new rubber roller rest for some time, allowing it to adapt to environmental conditions—temperature and humidity. This helps increase the material’s flexibility and improves its durability over time.
**Proper Storage After Use:**
Once the rubber roller is no longer in use, clean it thoroughly and store it in a plastic film. Place it on a dedicated roller rack rather than stacking it randomly or leaning it against a wall. This prevents unnecessary deformation and maintains the quality of the rubber.
