New Secondary Conveyor Belt Cleaner from Martin Engineering

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.

The Martin® SQC2S Orion Secondary Cleaner is appropriate for all bulk handling material applications. The unit is made up of individual 6 in. (152.5 mm) blades mounted on a square steel tube assembly. Not designed for reversing belts, it is suitable for 18 – 96 in. (457 – 2438.5 mm) belt widths, belt speeds up to 1200 fpm (6 mps), and temperatures up to 250º F (121º C).

The second level of tensioning is on the individual blade assembly. Each Orion blade assembly is attached to a steel square tube assembly which is secured a mounting plate. The square tube houses a rubber tensioner with a torsion arm bolted to each side. A specialized tungsten blade is attached to the arm. The whole system is mounted at a 90-degree angle then tensioned so each blade is vertical and perpendicular to the belt. As the belt runs, each blade assembly adjusts independently to precisely match the belt’s profile, permitting them to compensate for camber, flaws/blemishes, and stubborn material stuck to the belt’s face. To accommodate belt cupping and other uneven surfaces, the blade assemblies can be individually adjusted to match the belt profile.

The blades are specially designed for heavy-duty abrasive applications in both dry and wet environments. Tested on hard rock and slurry belts, the Orion blades offered superior cleaning results with a longer equipment life. This is due to the rugged tungsten carbide core surrounded by mild steel. Blades are also available in stainless-steel for specific corrosive materials.

The blade design features an attached deflector shield made from polypropene or rugged nylon for high temperature applications. Mounted directly to the blade in an outward scoop design, the shield ushers loosened material away from the mainframe and toward the discharge chute. This mitigates buildup on the assembly, extending the blade’s effectiveness and reducing the amount of maintenance.
