Drum coating with hot vulcanization and egments on conveyor belt systems

METHOD OF DRUM COATING

1. HOT VULCANIZATION IN THE AUTOCLAVE at the factory

Hot vulcanization

2. Segmental lining of operating, tension rollers with rubber coated metal segments is done in three ways:

2.1. DIRECT WELDING ON SEGMENTS OF THE DRUM

Direct welding of segments on the mantle roller conveyor may be assembled in the field in a very short period of time.

PREPARATION: The release of rubber roller. Removing the tape from the roll.

2.2 THE SYSTEM OF EXCHANGEABLE SEGMENTS WITH RAILS WELDED ON THE DRUM MANTLE

The system involves welding a “T” profiles on the mantle of the drum through which run rubberized metal segments. This system allows quick replacement wasted parts during operation.

The advantage of the coating roller segment relative to the hot vulcanization or cold autoclave and procedure

  • On the field in a very short period of time.
  • Time delays and losses minimized.
  • Installation is performed with a much smaller number of editors.
  • Reduced costs of assembly and disassembly of rollers from the conveyor.
  • Eliminated pasted materials (especially tensioning rollers) .
  • Doubled service life of the coating.
