DTII Belt Conveyor Impact Roller for Mining Machinery

The DTII Belt Conveyor Impact Roller is a specialized component of the DTII conveyor system, an advanced version of the TD75 standard, widely used in mining, coal, ports, and other heavy industries. Designed for the loading points of belt conveyors, these rollers absorb the shock of falling materials, such as coal, ore, or aggregates, to protect the conveyor belt from damage. Featuring rubber rings, rubber linings, or rubber coatings on a steel core, DTII impact rollers reduce impact stress, extend belt life, and ensure smooth operation in harsh mining environments.

Built to withstand abrasive, corrosive, and high-impact conditions, these rollers minimize downtime, reduce maintenance costs, and enhance conveyor reliability. This page covers what DTII impact rollers do, where they’re used, how to install them, what users say, and answers common questions, all in plain language to help you decide if they’re right for your conveyor system.

1. The conveying capacity in the table is calculated based on horizontal transportation, with a dynamic stacking angle of 20° and a roller groove angle of 35°.
2. The belt speeds of 4.5m/s and 5.6m/s in the table are non-standard values and are generally not recommended for use.

Installation Guidelines:

Installing DTII Impact Rollers is straightforward with these steps:

1. Verify Specifications

   • Ensure the roller’s diameter, length, rubber ring thickness, and frame design match your conveyor’s belt and loading point requirements.

   • Confirm the frame can support the roller’s weight and material impact loads.

2. Position the Rollers

   • Install impact rollers at loading points where materials are fed onto the belt, typically spaced 0.5-1 meter apart based on belt width and load [].

   • Use sturdy frames to secure the rollers, ensuring they align with the belt’s trough angle (20°, 35°, or 45°).

3. Align the Rollers

   • Set rollers perpendicular to the belt to ensure even support and effective shock absorption.

   • Use a laser level or string line to align rollers with adjacent idlers for consistent performance.

4. Inspect Bearings and Seals

   • Verify bearings are lubricated with lithium soap grease and triple labyrinth seals are intact.

   • Avoid disturbing seals to maintain dust and water resistance.

5. Adjust Belt Tension

   • Set tension to keep the belt taut without overloading the rollers. Use:
     [ T = \frac{P_p \cdot 1000}{v} ] where (T) is tension (Newtons), (P_p) is power (kilowatts), and (v) is belt speed (meters/second).

6. Test the System

   • Run the conveyor at low speed with a light load to check roller performance, shock absorption, and belt alignment.

   • Adjust roller positions if the belt shows uneven wear or material spillage occurs.

Installation Tips

• Use trained technicians to meet safety and industry standards.

• Document installation details for maintenance records.

• Contact [Your Company Name] for expert installation support.

Maintenance Tips

Regular care keeps DTII Impact Rollers performing well:

• Inspect Regularly: Check rubber rings, rollers, bearings, and frames every 3-6 months for wear or damage.

• Lubricate Bearings: Apply lithium soap grease every 6 months to ensure smooth rotation.

• Clean Rollers: Remove material buildup from rubber rings to maintain shock absorption.

• Check Alignment: Ensure rollers remain perpendicular to prevent belt drift.

• Use OEM Parts: Replace with DTII-compliant parts to maintain performance.

• Avoid Damage: Do not strike rollers or frames with heavy objects to prevent damage to bearings or seals.
