Super heavy-duty conveyor belt cleaners
for severe operating conditions

Martin Engineering from Neponset, IL/USA has developed a family of primary conveyor belt cleaners for the world’s fastest, most heavily-loaded belts with industrial-strength construction that delivers effective cleaning, minimal maintenance and long service life, even under punishing conditions. Martin® SHD Cleaners have been proven on belts up to 305 cm wide, with speeds as high as 10 m/sec carrying loads up to 300 000 tons per day. Designed with patented “CARP” technology to achieve constant angle geometry to match pulley diameter accurately across all stages of service life, the massive urethane blades deliver up to 271 cm² of wear surface – more than seven times the wearable surface of standard cleaner designs (Fig. 1). With a broad range of color-coded, high-performance blade choices available, the cleaners can be specified to suit a wide variety of materials and performance requirements.

The SHD Series was developed for super heavy-duty applications, with structural steel components to prevent bending of the main frame (Fig. 2). The extremely durable construction helps eliminate carryback, reduce ­emergency outages and minimize unscheduled downtime. In some applications, it has been shown to be the only design that can withstand the severe operating conditions.

“This design can allow conveyor operators to improve maintenance planning and reduce expenses,” observed Product Engineer Daniel Marshall. “With lower maintenance requirements, it saves money through fewer repairs and blade replacements, as well as faster service procedures,” he said. “The reduced carryback means improved working conditions and plant safety, maximized equipment life and reduced cleanup.”

The SHD 1200 Series Cleaner is built for high-speed conveyors with a head pulley larger than 122 cm in diameter and belt widths from 107–305 cm. With blades up to 30.5 cm tall, a heavy structural steel frame prevents bending, even with high tonnages and large lumps. The SHD 1200 was designed in tandem with its tensioner system (Fig. 3) to provide effective cleaning and reduced service requirements. Fully compatible with reversing conveyors and belts with mechanical splices, it has a service temperature range of -34 to 149 °C and can be used in corrosive conditions or underground applications.

Like its larger cousin, the SHD 600 Series Cleaner is installed in the primary position, but is designed for pulleys smaller than 120 cm. Built for tough, mine-grade cleaning, the unit ‘s durability has been proven in some of the bulk handling industry’s toughest applications.

“The SHD Series was originally designed for a severe-duty mining application, built to handle the overburden at one of the largest pit mines in the world,” Marshall continued. “Every cleaner they tried was getting destroyed by the harsh conditions. There just wasn’t anything on the market that could withstand the speed and abrasive forces, so we completely re-engineered the conventional belt cleaner design, from the I-beam frame to the huge blade segments. In fact, these cleaners are so large that we had to invent a way to properly tension them,” he said.

The SHD product family is finding utility in a variety of industries, where-ever applications involve large high-speed belts. The series is among a number of Martin Engineering products helping conveyor operators satisfy the demands for larger, faster systems that can move more material, without sacrificing safety or component longevity.
