3 Description of the product

3.1 Design and function

The Martin® DT2S secondary cleaner is primarily installed in a cleaner system consisting of pre-cleaners and secondary cleaners, but can also be used as a single cleaner.

The cleaner is installed directly behind a head pulley or tension pulley. Its slide-on blade holder enables quick and easy maintenance.

When the blades are properly selected, it can also be used on reversing conveyor belts or conveyor belts with a high return flow rate - also refer to the type description.

The cleaner can also be used in connection with mechanical joints if they are in good condition and optimally installed.

Although pre-cleaners and secondary cleaners can each be used individually, the installation of a system consisting of pre-cleaners and secondary cleaners is recommended for an optimal cleaning result.

WARNING RISK OF INJURY!

Body parts and/or clothing may get caught and pulled in by rotating parts or by the moving conveyor belt.

Shut off the power supply to the conveyor system and its accessories and secure it against unauthorised reactivation before performing any installation or maintenance work. Use warning signs!

NOTE

Figure 23 is an example of a cleaner.

Fig. 23

1. If the secondary cleaner (4, Fig. 23) raises the conveyor belt (1, Fig. 23), then a pressure roller (2, Fig. 23) must be installed above the contact point between the blade and conveyor belt at a clearance of 51 mm against the running direction (3, Fig. 23) to support the conveyor belt.

2. Remove all tools and fire protection covers from the installation site and the conveyor belt.

3. Operate the conveyor system for one hour under load.

Page 39

CAUTION RISK OF DAMAGE!

Only operate the fully loaded belt cleaner on the running and fully loaded conveyor belt.

4. Shut off the conveyor belt system after the one-hour operation under load, shut off the power supply and secure it against unauthorised reactivation.

5. Check whether all of the fastening parts are securely tightened. Tighten any loose connections.

6. Inspect the belt cleaner for the following conditions:

• Wear: minor phase-in wear is normal. This stops as soon as the blades have adjusted to the shape of the conveyor belt.

• Bulk material accumulation: No bulk materials may accumulate between the blades and return side.

7. Note the corresponding information in Section 7 "Troubleshooting" in cases of excess wear, bulk material accumulation or other problems.
