|This quarry decided to use the loose fibre system for the fibre addition to the coating plant to make Stone Mastic Asphalt. The fitters devised a system which ties into the current plant controls. It eliminates the need for manual handling of fibre bags and repeated entry to the plant to add pellets. The 1 tonne bags have to be raised above the hopper before they can be untied. To ensure that no one is under a supported load, the site installed a bag support frame, which is a sturdy reinforced piece of equipment that ensures no-one risks being crushed by the bags.
