Pre-Cleaners

As the first stage in a multiple cleaner system, the pre-cleaner removes the majority of materi­al adhered to the belt, leaving only a thin layer of sticky fines.

Pre-cleaners are generally ten­sioned at low pressure-roughly 2 psi (13.8 kPa)-against the belt. Low blade-to-belt pressure allows the pre-cleaner to be positioned at a peeling angle against the belt. The use of higher pressure at this angle would endanger the belt, splice, or cleaner itself.

Pre-Cleaners are typically installed on the face of the head pulley, just below the material trajectory. Cleaner should be constructed to avoid material buildup, and installed so it is out of the material stream.

MARTIN® High-Performance Urethanes
Martin Engineering is the leader in the development of high-performance urethanes for specialized applications. These color-coded urethanes can be supplied in blades for any MARTIN® Pre-Cleaner, as well as any pre-cleaner supplied by another manufacturer.
To specify a high-performance urethane, add the appropriate suffix (shown below under the blade color in parenthesis) to the part number of the cleaner assembly or replacement blade.
