Following a thorough assessment of the situation, the Martin Engineering Mexico team determined that a Martin QC1 Cleaner PD (Performance Duty) should be installed at each of the seven conveyor discharge points. Integrated onto the existing mainframes, the units are comprised of a single urethane blade connected to a steel mandrel, which is turned by a heavy-duty spring tensioner, retaining a tight seal on the belt. The blade design utilizes patented Constant Angle Radial Pressure (CARP) technology to maintain an efficient cleaning angle throughout its service life, without damage to the belt or splice.

For applications involving belt speeds of up to 900 fpm (4.6 m/sec) and service temperatures of -40° to 160°F (-40° to 70°C), operators can choose between 5 different blade types to address the characteristics of specific kinds of cargo for each conveyor. Available in lengths of 18 to 96 inches (457 to 2438 mm), blades can also be ordered in 10-foot (3.05 meter) slugs, allowing operators to cut to length for increased versatility.


The unit features a no-tool replacement process that can be performed safely by a single worker who simply pulls the locking pin, unclamps the bracket and slides the blade out of the mainframe. The new blade is slipped on and clamped into position, significantly reducing maintenance and replacement time.

Immediate Results

The performance of the system with the newly installed equipment was evaluated over a 28-day period, measuring the buildup of carryback as compared to the month prior to installation. Operators reported approximately 90% less fugitive material over the entire evaluation period, resulting in a drastic reduction in labor and downtime needed for cleanup.

Plant managers predict that the upgraded belt cleaning system will extend the life of idlers and other conveyor components, minimizing unscheduled outages due to equipment failures. Moreover, operators confirmed that worker morale was greatly improved due to the easier cleanup and better working conditions.
