deployed using a phased approach to minimise a massive initial capital outlay .
Becker Mining has recently upgraded its BRS-2 belt-rip detection system to enhance the productivity and safety of conveyor belts , by detecting longitudinal rips as soon as they occur . This system , which utilises inductive loops that are embedded in the belt , uses real time diagnostics to continuously monitor the status of the belt . In the event of a rip , the system stops the belt drives , which reduces any further damage and minimises downtime . Apart from the detection of belt rips , this system is designed for monitoring belt speed , the detection of belt slip and also for belt sequence control .
The high-accuracy Becker Varis Smartsense ® gas monitoring system – which can be calibrated in situ with integrated features for the detection of ambient temperature , humidity and barometric pressure , as well as gas monitoring - forms an essential part of the total belt solutions package . According to Becker Mining specialists , it is important to monitor gases emitted into the atmosphere in real time and have a reliable system to take immediate automatic action to eliminate the possibility of poisonous environments , as well as explosions .
The Smartsense system , with its integrated controller functions , operates as a ‘ black box ’ and stores important information , which could be critical in a post-incident investigation . The ‘ watchdog ’ feature alerts the user and
The Model DB belt rip detector , manufactured by Conveyor Components Company , is a mineduty and quarry-duty belt rip detector , which operates on a simple cable pull concept . When a belt flap or tear , or a foreign obstruction such as a wrench or screwdriver or piece of rebar has pierced a conveyor belt , the cable releases the activation ball from its protective socket and trips the device .
The outputs of the Model DB can control up to four separate circuits , depending on the model chosen , as either SP / DT or DP / DT microswitches are available . These alarms can include one for
maintenance teams of any system errors , for example , if the system has detected inaccurate measurements or calibration errors . This information is displayed on the large LCD display , as well communicated remotely on the supervisory platform .
Motor protection systems offer protection for cables and all types of electric motors , with reliable features for motor condition and overload monitoring , as well as phase detection and visualisation of motor operating parameters .
Becker Mining ’ s Pull Key systems are integrated with conveyor protection devices into one system , with one cable , to suit exact conveyor belt requirements . Pull Keys , which are suitable for use in IS and non-IS environments , comprise a control panel with a 4-line display unit , expandable inputs and outputs on-board , communication with SCADA and various other platforms , as well as intercom options .
Surveillance systems comprise a range of cameras and video management solutions , including explosion proof , audio and visual announcement and video analytics options . These advanced devices , which are designed with intelligent bandwidth compensation and increased storage capacity , offer tamper detection and cyber security . Thermal and radar devices allow for detection , even in low light , tough conditions .
Distributed sensing systems play an important role in the early detection of equipment failure , to improve efficiencies , prevent costly repairs and reduce downtime . These systems continually monitor frictional heat , as well as temperature and vibration , throughout the conveyor system . This sensing system detects wear and tear early and monitors the electrical infrastructure , where heat builds up on transformers , electrical connections and joints . The early leak detection system accurately detects and identifies the location of leaks along pipelines .
Dust suppression systems are an important component in Becker Mining ’ s total belt solutions and are effective in the suppression of particulate matter , which can cause health problems for workers . These dust prevention and reduction systems , which conform with Mine , Health and Safety Act requirements , are fitted with fully adjustable spray patterns , flow rates and nozzle configurations .
Fire protection and suppression systems also play a critical role in Becker Mining ’ s belt management package . A deluge valve coverage of up to 40m of the conveyor belt , allows for water to be sprayed over the entire area , which mitigates the risk that fire will spread out of the coverage area .
Becker Mining offers a technical advisory , product selection , installation and maintenance service throughout the continent . A specialised consulting , training and support facility ensures optimum efficiency of a wide range of equipment and total safety for workers .
Belt rip detector saves downtime
machinery shutdown , which minimizes further conveyor belt damage , and one for alarm .
The Model DB is a very cost-effective unit , in both design and installation , that provides similar benefit to the very expensive embedded coil devices on the market . This standard housing construction is corrosion resistant cast aluminum , with an optional polyester or black epoxy powder coating . The protective rubber boot on the cable assembly keeps the activation mechanism clean and functional , and is easily replaced if damaged .
