A Secondary Cleaner is the second stage in a multiple belt cleaner system. Its purpose is to remove residual fines that remain on the belt past the Pre-Cleaner. The mounting location of a Secondary Cleaner is typically close enough to the material trajectory that the cleanings will stay within the main material stream. These second stage cleaners are installed at the point where the belt is leaving the discharge pulley. For some applications, a third stage or Tertiary Cleaner is required for final cleaning. A Tertiary Cleaner can be the same model as the Secondary Cleaner, or of a different design which enables efficient cleaning and maintenance within the available space.
Because of space limitations, Secondary Cleaners are typically installed away from the discharge pulley, therefore they should be placed at or near a point where the belt is against a roller, or a support roller should be installed. This firm support prevents the Cleaner's tensioner pressure from raising the belt line and thereby reducing cleaning efficiency.
As you would expect, because of the significantly different characteristics of materials that are conveyed, and the type, speed and design of belt conveyors, MARTIN® offers a broad range of blade shapes, sizes, and blade-materials; frame configurations; and types of tensioners to provide the most effective solution in removing any type of carryback while protecting the belt and its splices.
