A conveyor belt fire is not only very dangerous and fast spreading but also very costly. Conveyors are easily ignitable and a fire can develop from many places: the material being conveyed, the electromechanical components and bearings of the system, or the belt itself. Therefore, continuous conveyor belt temperature monitoring is very important.
Conveyor belt fires can present a serious hazard in the confined environment of an underground coal mine. To minimize this hazard, Federal regulations were enacted following the Federal Coal Mine Health and Safety Act of 1969 to require the use of acceptable fire-resistant conveyor belts and suitable belt slippage-sequence switches, fire warning devices, and fire suppression systems.
Material handling constitutes a major component of production and maintenance costs at mines, ports, cement plants, and iron and steel mills. Honeywell’s BeltAIS™ conveyor monitoring solutions help users maintain and optimize their conveyor belt systems, leading to enhanced overall equipment effectiveness (OEE), improved reliability and uptime, and lower maintenance costs.
Uptime and safety are critical factors for conveyor belt operators. A key focus of our system is monitoring temperature change as coal is transported along the conveyor. Given coal’s highly explosive nature, monitoring temperature increases and alerting operators, provides advanced warning so they can take action and avoid critical events.
Fire protection for conveyor belts. Automatic conveyor systems are the lifeline for many companies. They guarantee continuous flows of material and goods by transporting these items to all areas in the company, through openings in fire walls and ceilings. This is where so-called conveyor

ifm's product range for conveyor belt system monitoring covers belt drift switches, safety rope emergency stop switches, motor switches, compact speed monitors and 3D sensors. The belt drift switch is used to protect the belts from damage or destruction in case of belt
Conveyor belts represent a high risk, because they have the ability to spread a fire over long distances. Fires on belt conveyors are mostly ignited by mechanical failures like frozen idlers, which is even more dangerous in combination with coal dust. The fire safety requirements are similar for the most hard coal mining countries.
Apr 17, 2017· Fiber Optic Temperature Monitoring of Belt Conveyors on April 17, 2017 Major conveyor belt–related mining incidents are now relatively infrequent as a result of recent improvements in engineering standards and the use of fire-resistant materials.
The Mine Ventilation Society of South Africa (MVSSA) has published the results of a study where they compare different fire prevention and detection systems for mine conveyor belts. Conveyor belt fires are one of the leading risks, especially in the underground mining industry. Often combustible materials are used on and around the conveyor installation.
Dear Conveyor Belt User, The ConveyorBeltGuide is providing practical information about heavy duty conveyor belts, which normally is not found on commercial websites. It is permanently growing and improving. You are kindly invited to send your comments or questions. With your support this guide will become better and better for the benefit of all who are working with this great product.
Since the belt conveyor fire detection application performs detection in 1-meter units at least every 10 seconds, it easily identifies the source of the accident. And as a total Yokogawa solution, you can customize the monitoring system to output monitor screens and reports that mirror the needs of
Transporting coal by means of conveyor belts is common in Australian underground coal mines. Major conveyor belt–related mining incidents are now relatively infrequent as a result of recent improvements in engineering standards and the use of fire-resistant materials. However, conveyor
The conveyor belt fire models used are the 2:1 ratio due to the ability to fit them close to the pulleys. A typical installation is shown in Figure 7. As for the bearing temperature monitoring, if a temperature of 68°C is measured on the surface of a pulley, the belt is tripped and an alarm sounded.
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
Conveyor Fire Detector landinst Conveyor belts are expensive and replacements can carry long lead times maximise your belt life and plant productivity by detecting hotspots before problems occur. Key Features & Benefits Fire detection using highly accurate temperature monitoring Monitor and protect the entire conveyor even small
Off-tracking belts running into the side of conveyor equipment will cause friction, which may cause damage to the belt, and may generate heat, fire, or a dust explosion. The RB200DN is very easy to install, it will be fitted on both sides of a conveyor or elevatorbelt.
The fire alarm. There are various options of how to action a fire alarm when detected on a conveyor belt. On longer conveyor belts, the detections systems are zoned to smaller conveyor lengths, for example 20 m or 40 m this makes it easier to get to the fire.
envelop, at a net rate of not less than 10.2 (L/min)/m2, the top and bottom belt surface area, conveyor surfaces where combustible materials are likely to accumulate, the structural parts, and the idler-rolls supporting the belt. Disadvantages • Belt on fire when system is actuated, belt
Detecting moving fires on coal conveyors. To comply with certain elements of the Clean Air Act Amendments of 1990, a number of utilities operating coal fired power plants have switched to low-rank
The conveying of waste presents a seemingly endless supply of materials and substances that damage and destroy rubber conveyor belts. The often highly combustible nature of household waste in particular also means that having belts with first-class fire resistant properties is extremely important.
Jul 03, 2019· Conveyor Belt Monitoring: New Technologies for the Protection of Conveyor Belting. July 3, 2019 Marcel Droettboom Leave a comment 924 viewed. By A. van Staden In mines and many plants of the processing industry conveyor belts are the lifeline of the production system. It is, therefore, of paramount interest to keep the conveying system up
A fire condition within a conveyor system represents either a static fire — on a stationary conveyor belt or within the conveyor’s mechanism or housing — or a moving hazard: hot or burning
to glow. Especially when a belt conveyor is at a standstill, a large fire hazard can arise after just 10 to 15 minutes. By implementing fire-resistant idlers with polyurethane support rings, preventing dirt from entering the system and having the company fire department regularly monitor the entire conveyor lines during operation, it was
