New Secondary Conveyor Belt Cleaner designed for safety and easy maintenance
The global leader of belt conveyor accessories has announced the next generation of secondary conveyor belt cleaners engineered to reduce dusty carryback and lower maintenance time. Designed to withstand the stress of heavier loads carried on wider, thicker belts at higher speeds, the Martin® SQC2S Orion Secondary Cleaner features individually cushioned tungsten carbide blade cartridges for effective cleaning without risk to the belt or splices. A two-tiered tensioning system means minimal adjustments and monitoring throughout the life of the blade. The heavy-duty blades are mounted on a slide-in/slide-out assembly for faster and safer one-worker external servicing. The result is improved belt cleaning with less dust and maintenance for greater workplace safety at a lower cost of operation.
“We field tested the Orion over several months side-by-side with competitor designs in punishing mining environments

and found that the new design significantly outperformed the competition,” said Dave Mueller, Conveyor Products Manager for Martin Engineering. “At the end of the testing period, customer participants started the process of replacing all their heavy-duty secondary cleaners with the Orion. We now view this design as the future of our secondary cleaner line moving forward.”
Secondary cleaners play an essential role in the belt cleaning process by significantly reducing the volume of dust and fines dropped as carryback on the belt return. Primary cleaners release most of the abrasive material remaining on the belt after discharge. Located below the head pully just behind the primary, secondary cleaners scrape off the fines and dust that hide in cracks and divots in the belt. Carryback is attributed to many environmental and operational issues such as air quality violations, fouling of rolling components and machinery, and increased labor for cleanup and maintenance.
Cartridges with individual tensioning improves cleaning efficiency and effectiveness.
The mounting assembly firmly secures the secondary cleaner to the stringer.
Slick heavy duty deflector shields improve performance from wet applications that experience buildup.
