MARTIN® Belt Cleaning Systems
Martin Engineering's THINK CLEAN® Philosophy
As the world's leading developer of engineered belt cleaning systems, Martin Engineering has developed fundamental principles for cleaner design and per¬formance. This philosophy notes that:

Multiple cleaners are required for superior per¬formance.
The cleaning system should be matched to the conveyor, material, and conditions.
Cleaners should be as far forward (as close to the discharge) as pos¬sible.
Cleaners should be installed out of the mate¬rial flow.
Cleaners must minimize risk to operator, belt, splice, and cleaner itself.
Cleaners should simplify maintenance.

For Efficiency, Multiple Cleaners
For effective carryback removal without risk to the belt, splices, or the cleaning system, the best solution is a system of several cleaners.
Different Cleaners, Different Roles
A pre-cleaner is installed on the face of the discharge pulley to remove the majority of the material adhering to the belt. One or more secondary cleaners remove the fines that remain past the pre-cleaner.
Engineered to Reduce Risk
Cleaners must utilize low pressure and compatible angles of attack to prolong blade life, minimize risk of damage, and prolong the service life of belt, splice, and cleaner.

Keep the Pressure On
Martin Engineering's Belt Cleaner Tensioning Systems maintain cleaning efficiency over long intervals with minimal adjustment.
Cleaners To Match Your Needs
Martin Engineering offers the most comprehensive line of belt cleaning systems available to suit your conveyor, your material, and your budget.
Regular Service Boosts Efficiency
Maintenance is often the key to a successful cleaner installation. Martin Service Technicians (MSTs) can provide the maintenance necessary to maintain cleaning efficiency.

Urethane Blade
Provides Final Cleaning
Pliable urethane blade conforms to moving belt to remove water and pull material from imperfections in belt surface.
Water Spray Improves Performance
Recommended spray system moistens belt-borne material to improve cleaning and dust control

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.

Engineered for
Superior Performance
MARTIN® SHD Cleaner and SHD Spring Tensioner are "systemengineered" for constant pressure and consistent cleaning without needing adjustment during the life of the blade.

Secondary Cleaners

Secondary Cleaners remove the residual fines or slime that has remained on the belt past the pre-cleaner. More than one secondary cleaner may be required to reach the desired
level of cleaning.

A secondary cleaner is typically installed at the point where the belt is leaving the discharge pulley. This is typically close enough to the material trajectory that the cleanings will return to the main material stream.

Sometimes a secondary cleaner(s) must be positioned farther from the discharge point; an extended dribble chute or scavenger conveyor may be required to return the carryback to the main material stream.

Tertiary Cleaners
Additional cleaners can be installed to provide final cleaning. These cleaners can be the same model as the secondary cleaner, or of a different design to allow efficient cleaning and
maintenance within the available space.

As these cleaners are typically installed away from the pulley, they should be installed at or near a point where the belt is against a roller. Firm support will prevent cleaning pressure from raising the belt line and reducing cleaning efficiency. It may be necessary to add a roller to provide this support.

The MARTIN® SQC2™ Secondary Scraper uses individually-cushioned tungsten carbide blades for effective cleaning without risk to belt, splice or blade. Installed in the secondary cleaner position, the MARTIN® SQC2™ Secondary Scraper incorporates rubber blade buffers to cushion impact and maintain cleaning pressure.

Specialty Cleaners

MARTIN® WASHBOX™ Belt Cleaning System
Spray applies water to improve cleaning efficiency.
Installed as a secondary cleaner along the conveyor's return run, the MARTIN® WASHBOXTM Belt Cleaning System provides the ultimate in belt cleaning technology. Rather than "blasting" material from the belt, the water spray softens the carryback for effective cleaning with MARTIN® Secondary Cleaners.

Mounts and Tensioners

	Mounts & Tensioners MARTIN® TWIST™ Tensioner The patented MARTIN® TWIST™ Tensioner uses a set-resistant rubber tensioning element to supply cleaning pressure. Simple to install and set, the compact MARTIN® TWIST™Tensioner is recommended for use with most Martin Engineering Pre- and Secondary Cleaners. "Once-In-A-Lifetime" Maintenance Rubber element resists "set" better than urethane; requires adjustment only at midpoint of blade wear. No Risk to Worker Self-relieving design allows cleaner blade to pull through while tensioner releases force without external action to injure employees or damage equipment.
	Alternative MARTIN® Tensioners Tensioning systems to suit individual conditions and preferences. MARTIN® Air Tensioners Patented design uses an air spring (air bag) to store pressure. Martin Engineering recommends connecting to plant compressed air system.
	Alternative MARTIN® Tensioners MARTIN® Spring Tensioners Incorporates steel spring to provide pressure for efficient cleaning. Simple-to-adjust spring easily tensions to proper pressure.
	Alternative MARTIN® Tensioners MARTIN® Plant Air Connection Kit Used to connect air tensioner(s) to plant air system for consistent cleaning pressure while reducing maintenance requirements. (P/N 31772)
