Scraper

Application

A multi cleaner system (Primary & Secondary) adopted by Rexline has become a common standard for all conveyor cleaning applications

Rexline offers Segmented Sprung Elastomount Multi-Blade Scrapers with individual tips, which are self-adjusting.

Engineering

Basic factors considered for optimum performance

  • Material Abrasiveness
  • Moisture Content
  • Corrosion Characteristics of Material
  • Lump Size
  • Capacity

Cleaning Elements

  • Tungsten carbide
  • Tool steel
  • Polyurethane
  • Stainless Steel
  • Polymer
  • Rubber

Fundamental Principle

Conventional – less than 90 0- resulting in more frictional force- fast tip wear out and hence less cleaning efficiency.

Rexline – more  than  90 0- resulting in negligible frictional force-longer tip life and higher cleaning efficiency.

Type of Scrappers

Primary Scrapper

Designed for fitment on the head pulley. It breaks the material-to-material adhesion after the discharge trajectory.

Secondary Scrapper

Designed for fitment after the tangential take off point between the Head and Snub Pulley (where the flapping action would be the least). It removes the material in the form of fine particles adhering to the belt.

Reversible Scrapper

Designed for fitment on Reversible Belt Conveyors at both end pulleys after the tangential take off point.
