A new conveyor belt cleaner has been engineered to contain a smaller total volume of urethane, while maximizing the usable area, produced in a streamlined process. By minimizing the non-consumable portion of the blade, the heavy-duty primary belt cleaner delivers the same performance and durability as the model it replaces, while reducing the amount of urethane going to landfills.

Manufactured with Martin Engineering’s unique “CARP” (Constant Angle Radial Pressure) technology to maintain the most efficient cleaning angle throughout its service life, the QB1 Cleaner HD features a no-tool replacement process that can be performed safely by one person in less than five minutes.  

“We’ve simplified the manufacturing process and also re-engineered the blade itself,” explained global engineering manager Paul Harrison. “The new profile will be less complex to produce, and because it can be roll formed or manufactured on a press brake, it will be easier to source throughout the world from any Martin Engineering manufacturing site.”
 
The reduced weight will also facilitate easier blade replacement, and the one-pin mounting system helps reduce downtime for maintenance. To replace the QB1, maintenance personnel simply pull the locking pin, unclamp the bracket, and slide the blade out of the mainframe. The new precut blade is slipped onto the square mainframe and clamped.  

The exclusive CARP technology is designed to keep the blade at a consistent angle and pressure against the belt. Typically set at about 2 psi for the QB1 HD, the low blade-to-belt pressure helps protect the belt, splice, and cleaner itself. As the blade wears, neither the surface area nor the angle is compromised, ensuring maximum performance throughout its life.

To introduce material back into the product flow, the QB1 HD is installed on the face of the head pulley. On a dual cleaner system, the new pre-cleaner is installed immediately in front of the secondary cleaner. For applications involving enclosed pulley chutework, Martin Engineering recommends that one of its steel inspection doors be installed.
