Harris--A Difference You Can See

Visitors to a Harris shredder plant can see the difference. Sturdier design. Thicker plates of steel. Larger, heavier, castings. Interlocking fabrication using the most rugged bolts and fasteners on the market.

Owners of Harris shredders know that the differences go beyond appearances and into the critical operations aspects of production and output, ease of maintenance, minimization of downtime and dependability and reliability.

From the double feed roll assembly through the shredding plant and up to the technologically-advanced control booth, Harris shredders offer features that make them stand out from the rest of the market. The engineers, designers, fabricators and installers at Harris work with one goal in mind: to produce shredders that endure. Harris shredders are designed for maximum production that minimizes downtime and will provide quality scrap for years and years to come.

"We’re confident that our design reduces delays and unexpected downtime," states Harris VP Doug Sebastian. "We do it through our advanced engineering design, heavy-duty construction, large castings and overall solid construction of the machine."

To build shredders that are up to the tough daily task of turning trucks, cars, appliances and plate steel into a shredded product, Harris starts with design features and parts specifications that ensure a rugged machine is being created.

Harris engineers and fabricators work closely together to provide a complete system design that leaves nothing to chance. A system is created for each customer that suits the specific application and the scrap stream that will be encountered.

The custom design starts with the infeed conveyor and runs through to the downstream system that will identify, extract and sort materials to meet customer requirements.

The Harris difference starts with Base Weldment and spring box-mounting technology that isolates vibrations and reduces vibration-related damage to key components.

It continues with Harris’ exclusive heavy-duty double feed roller design, built with a sturdy steel plate yoke and equipped with hydraulic-actuated locks and a quick release connection to allow for easier maintenance. "It’s a terrific safety feature, providing a better way to maintain that part of the plant than previous designs," notes Javier Herrera. "We’re getting a lot of good response to this, even from operators of existing shredders who would like to have it installed."

The shredding mill itself is designed and manufactured with thicker steel, larger castings and fewer liner bolts—all working together to allow operators to shred at a lower cost per ton while taking less downtime for maintenance.

Harris-built rotors are available in disc or four-arm spider configurations and are made from specified, hardened alloys for longer wear life. Replaceable heavy-duty helmet caps further protect the spiders.

The rotor sits inside an innovative, reversible hood that has also been designed for longer component life. "The reversible hood means that after it wears on one side, you can reverse it and use it on the other side for another long stretch of shredding," says Sebastian.

Harris shredders are operated from a control booth that features a combination of the latest in operator comfort, easy-to-use controls, and an operations and output reporting system that will provide operators with the information they need to monitor the shredding process and make adjustments if necessary.

This combination of sturdy, high-strength metallurgy, innovative design, ease of maintenance, critical safety features and state-of-the-art information technology has quickly vaulted Harris shredders to the forefront of the industry, explains Sebastian.
