A Conveyor Belt Fire Test Program was initiated in 1985 by the Approval and Certification Center Aamp;CC Mine Safety and Health Administration MSHA U.S. Department of Labor. The purpose was to evaluate the effect of entry air velocities on the burning properties of mine conveyor belts and assess fire test data from large- and small-scale tests.
A mistracking belt can contact the mainframe seriously damaging both the belt and the structure resulting in excessive spillage and even creating a potential fire hazard. News Markets
A video has emerged of the conveyor belt fire at the Cape Lambert port facility last Thursday. It is believed that the fire originated from hot work during a shutdown at the Rio Tinto JV Robe River facility. The Robe River facility separates lumps and fines that are predominantly exported to China’s coastal and North China niche steel mills.
Ampcontrol has a solid history of supplying conveyor monitoring and control systems to some of the longest conveyors in Australia. Our award winning iMAC monitoring and control system has been installed on conveyor belts measuring over 50km in length.
Analysis of the data leads to certain conditions of air velocity and sensor alarm levels that are required for early detection of conveyor belt entry fires. Two nomographs are presented which define sensor alarm levels and sensor spacings as a function of belt entry cross-sectional area and belt entry air velocity.
Aug 23 2015 Conveyor Belt Tracking Systems Reduce Hazards and Spillage. A global leader in bulk material handling solutions offers a family of responsive conveyor belt tracking systems that mitigate misalignment rather than correcting it after the fact — even on reversing belts — to promote conveyor efficiency and safety.
Aug 31 2015 To keep the belt centered in a reversing conveyor’s loading zones Martin Engineering recommends the installation of one reversing tracker at the entry and exit of each loading point.

Mar 25 2016 o Using a belt misalignment alarm to prevent rubbing and frictional heating as recommended in FM Global Datasheet 7-11 2.5.3. o Using a belt speed monitoring alarm and interlock to detect a stuck or broken conveyor belt as recommended in FM Global Datasheet 7-11 2.6.2 and required by NFPA 654 2013 184.108.40.206.
Near idlers along the belt structure. When the conveyor belt is stopped the coal fire then spreads to the conveyor belting and if the conveyor belt has poor flame-resistant properties the flame will begin to propagate along the exposed surfaces of the conveyor belt. As . the surface area of the burning conveyor belt increases so does the total
