VIDEO: Will It Break?

World Coal,

Smiley Monroe’s King Rollers have been proven to reduce workplace noise on enclosed high-speed conveyors, with the potential to install the rollers at coal mines and other energy-intensive operations.

The energy-saving polymer conveyor idlers have now been put through their paces in a ‘toughness’ video, in which the idlers come face to face with a man wielding a hefty sledgehammer.

In a gladiatorial battle of man vs roller, the King Rollers were tested for strength against a steel idler – which are usually used in conveyor systems found in coal mines and operations across the world.

The polymer idler is up to 50% lighter than a steel idler, making them easy and safe to handle. The light weight might at first seem to put it at a disadvantage in a strength test, however, you can check out how the two types of idlers fared in the short ‘Will It Break Video’ below:



Smiley Monroe say that their King Rollers can reduce conveyor power consumption by an average of 14%, thereby reducing CO2 emissions and operating costs per tonne.

Man vs Roller: the results

In the man vs roller challenge, the polymer idler received only minor bruising to its shell, whereas the steel idler was clearly damaged, with its shell badly dented.
