FEATURE www.rockproducts.com ROCK products • August 2019 • 85 Realizing Energy Savings Using A Ceramic Lined Rotary Valve In Place Of A Screw Pump Keith E. Kressley, Coperion K-Tron Energy saving is becoming a more and more important top- ic in the cement industry. The air supply (screw compressor) and the material feeding device into a pneumatic conveying line are the highest energy consumers of a pneumatic convey- ing system. For many decades the screw pump was the most frequently used material-feeding system, but screw pumps require extremely high electrical power. Looking on this dis- advantage of the existing technology, Coperion has adapted the well-known technology of rotary valves for the high wear application in the cement industry. This technology saves more than 95% of power compared to the screw pump. Noon – 1:00 p.m. Lunch on Show Floor 1:00 - 2:30 p.m. Sessions MSHA's Enforcement Focus on Structural Integrity at Cement Operations Bill Doran, Attorney-At-Law, Ogletree Deakins As a result of high profile accidents around the country involving structural failures, MSHA has placed a greater emphasis in its inspections on evaluating the structural integrity of silos, bins, buildings and conveyors. This has had a particular impact on cement plants. These enforcement evaluations tend to follow a familiar pattern beginning with general observations and concerns by inspectors, demands for third party examination, and moving to comprehen- sive analyses by MSHA technical support engineers. These issues can be difficult to resolve and often include requests for internal documents, allegations of unwarrantable fail- ure and failure to timely abate. This presentation will dis- cuss recent cases and offer some insight into how to effec- tively navigate the pitfall that can arise. High-End MSHA Training: Surviving an Inspection Brian Bigley, Cemex This is a high level overview of the key components of an MSHA inspection, and your role as an attendee. It will serve as a quick introductory primer for people who might have to go on, or manage an MSHA inspection, as well as a refresher for those that do them frequently. It includes discussions of your rights your company's rights, and min- er's rights and responsibilities. We will cover handling doc- ument requests, timely manner requests, the walk-around, and common problems that can arise during an inspection, along with advice on handling each aspect. Overcoming Safety Cop Culture: Practices to Move You from Enforcer to Ally Justin Ganschow and Zach Knoop, Caterpillar There is a spectrum of how safety is managed within orga- nizations, from authoritarian to democratic, and all leaders play a role in shaping that culture. Whether we wear the title of "safety" or not, how we interact with others in situations regarding safety expectations, performing assessments of work practices, or responding after an incident forms per- ception about our character. It starts with understanding the biological reflexes of reacting to challenging safety situations and then adopting cerebral, intellectual habits that are more effective solutions. This presentation will share how to over- come a "safety cop" persona, balancing leadership with col- laboration to help participants become trusted safety advi- sors and create an engaged safety culture. 2:30 – 3:00 p.m. Afternoon Break on Show Floor 3:00 - 4:00 p.m. Sessions Maximizing Conveyor Performance-Industry Standards Versus Real World Application Mike Cremeens, Shaw Almex and Dick McConnell, Flexco Contrasting industry standards with real-world applica- tions, attendees of this session will learn about conveyor belt construction, operational forces, transition distanc- es, tracking issues and other performance influences. This interactive presentation will provide the information nec- essary to better understand and troubleshoot real world belt conveyor performance issues. Both U.S. standards and International nomenclature will be covered. 1. Learn how conveyor belt construction and quality is designed to operate on a conveyor structure. 2. Understand rated tension versus operating tension and how to calculate both. 3. Know how to diagnose and resolve transition distance violations. 4. Conveyor belt splices both mechanical and vulcanized.
