Martin Engineering introduce heavy-duty conveyor belt cleaners

SHD cleaning units specially developed for fastest and most heavily loaded belt applications

MARTIN Engineering have unveiled a range of primary conveyor belt cleaners which, they say, have been specially engineered for the world’s fastest and most heavily-loaded belts, with ‘industrial strength construction’ delivering effective cleaning, reduced maintenance and long service life, even under severe operating conditions.

Said to work on conveyor belts up to 10ft wide, with speeds as high as 2,000ft/min (10m/sec) and carrying loads up to 300,000 tonnes a day, the SHD Series cleaners are suitable for super heavy-duty applications, with structural steel components that prevent bending of the main frame.

The extremely durable construction helps eliminate carryback, reduce emergency outages and minimize unscheduled downtime. In some applications, Martin Engineering say that it has been shown to be the only design that can withstand the severe operating conditions.

‘The design can allow conveyor operators to improve maintenance planning and reduce expenses,’ said Daniel Marshall, product engineer for Martin Engineering. ‘With lower maintenance requirements, it saves money through fewer repairs and blade replacements, as well as faster service procedures. The reduced carryback also means improved working conditions and plant safety, maximized equipment life and reduced clean up.’ 

Designed with patented ‘CARP’ technology to achieve constant angle geometry to match pulley diameter accurately across all stages of service life, the huge urethane blades on the SHD cleaners deliver up to 42 square inches 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 1200 Series Cleaner is built for high-speed conveyors with a head pulley larger than 48in diameter and belt widths from 42 to 120in. With blades up to 12in high, a heavy structural steel frame prevents bending, even with high tonnages and large lumps.

The SHD 1200 unit 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 from –34 to 49°C and can be used in corrosive conditions or underground applications. 

For smaller belt applications, the SHD 600 Series cleaner is installed in the primary position, but is designed for pulleys less than 48in.  Built for tough, mine-grade cleaning, the unit ‘s durability has been proven in some of the bulk handling industry’s toughest applications.
