36 • ROCK products • November 2017 EQUIPMENT & TECHNOLOGY MATERIAL HANDLING & CONVEYING The Model DB belt rip detector, manu- factured by Conveyor Components Co., is a mine-duty and quarry-duty belt rip detector, which operates on a simple cable pull concept. When a belt flap or tear, or a foreign obstructio 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 machinery shutdown, which minimizes further conveyor belt damage, and one for alarm. The Model DB is cost-effective in both design and installation, noted the company. 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 mecha- nism clean and functional, and is easily replaced if damaged. Conveyor Components Co., Martin Engineering Offers Conveyor Systems Tracking Technology As bulk-handling equipment suppliers continue to make use of new and evolv- ing technologies to develop "smarter" conveyor systems, Martin Engineering has introduced data tracking with QR codes on its belt cleaners. Customers benefit from regularly sched- uled inspections by factory-trained and MSHA-certified technicians, providing operators with easy access to a wealth of data on the application, operating environment, service life and condition of conveyor components, updated on every belt cleaner maintenance visit. By avoiding the common "run it until it breaks" approach, a Martin Engineer- ing proprietary smartphone app helps maximize performance and service life – while minimizing carryback and spillage – to improve safety and reduce unscheduled downtime. Currently being implemented in select markets around the world, the new tracking program captures a wide array of information to create a detailed record on all components. Date codes are imprinted on the blades during man- ufacture – very important for urethane because it has a limited shelf life – and technicians also affix tags on existing equipment to begin monitoring condi- tion and recording observations. Conceived as part of Martin Engineer- ing's factory-direct "Mr. Blade" program, technicians perform regularly-sched- uled inspections and adjustments, with an 18-point operational assessment from head pulley to tail pulley and a report for each visit. The visual inspec- tions include the condition of pulleys, belts and idlers, as well as belt tracking, sealing, support and containment. This constant vigilance contributes to greater safety, efficiency and dependability of the conveyor systems, minimizing haz- ards and unplanned outages. "Periodic reviews often reveal developing problems before they become a failure, such as worn idlers, leaking seals or excessive spillage," said Chris Schmelzer, director of the wear components business group, Martin Engineering. "The data tracking program will help us work with our customers to make better-informed decisions about what equipment to use in specific applications, more accurately predicting the expected wear life," said Schmelzer. "The goal is to help ensure that all components are properly serviced and replaced during scheduled outages, before a major break- down occurs and stops production." With the new tagging and capture abil- ity, component data can be recorded and analyzed in much greater detail than ever before. Every inspection a techni- cian makes will be logged, along with operational factors such as the mate- rial being handled, conveyor speed and remaining wear life, as well as visual observations and other info. The overall goal is to deliver more effective control of bulk material, improving predictive maintenance scheduling and contribut- ing to a lower total cost of ownership. The tagging program allows the com- pany to maintain detailed information about the product's date of manufacture, installation and service history, giving customers access to the data through a smartphone or other device. "Eventu- ally we will have enough data points to make more accurate predictions about the performance and wear life of indi- vidual blade designs and materials of construction under specific operating conditions," Schmelzer said.
