Martin Engineering’s new HD belt cleaner
By Andrew Macklin
September 23, 2015 – Martin Engineering’s newest line of primary conveyor belt cleaners has been engineered 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 10 feet (305 cm) wide – with speeds as high as 2,000 FPM (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 42 square inches (271 sq. cm) of wear surface – more than seven times the wearable surface of standard cleaner designs. 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. The durable construction helps eliminate carryback, reduce emergency outages and minimize unscheduled downtime.
The SHD 1200 Series Cleaner is built for high-speed conveyors with a head pulley larger than 48 inches (122 cm) in diameter and belt widths from 42-120 inches (107-305 cm). With blades up to 12 inches (30.5 cm) tall, a heavy structural steel frame prevents bending, even with high tonnages and large lumps. The SHD 1200 Series Cleaner was designed in tandem with its tensioner system 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 -30 to 300°F (-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 48 inches (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 product family is finding utility in a variety of industries, wherever applications involve large high-speed belts.
