Scrap metal would then adhere to the steel components of the separator belt, wedge underneath the cleats, tear the cleats from the belt and damage the belt surface. The downtime required for belt repair seriously compromised productivity. Installing non-magnetic components was quickly identi- fied as a long-term solution for the separator belt. Flexco recommended HD2 Tatch-A-Cleat mechanical belt cleats constructed from a durable SBR compound for high ten- sile strength and flexibility. Flexco Everdur 375 bolt-hinged fasteners constructed from non-magnetic stainless steel were also selected. As a result of the Tatch-A-Cleat installation, separation now continues virtually uninterrupted. The HD2 Tatch-A- Cleat measures just 2 in. high, so if scrap material wedges between the cleat and the belt, the easy-to-reinstall cleat is likely to detach cleanly. And because Tatch-A-Cleats can be quickly replaced – especially when compared to time required for belt repair – downtime is minimized and pro- ductivity maximized. www.flexco.com 4. Conveyor Solutions Monarch Cement needed assistance in increasing the sub- stitution rates of a challenging fuel: high-moisture petro- leum coke. The fuel's 50 percent moisture content made it difficult to handle and transport. The fuel needed grinding prior to firing in a kiln or calciner. It was agreed to dose the high-moisture petroleum coke with a FLSmidth Pipe Conveyor to the existing vertical coal mill. The pipe conveyor is a fully enclosed conveyor system that allows spillage-free conveyance of material, thereby reducing maintenance costs. Today, Monarch Cement substitutes up to 60 percent of its fuel with the high-moisture fuel. The system delivers the material to the coal mill at the rate the customer needs to have a very short payback. www.flsmidth.com/en-us/industries/cement 5. Drive Solutions In cement plants, drive solutions represent the link between electrical and me- chanical systems and it is therefore necessary to plan the drive system design to meet mechanical require- ments. As these mechanical modules usually originate from more than one suppli- er, their technical demands and specifications vary. Siemens SICEMENT Drive Solutions stand out because of their availability, energy efficiency, simple operation and ease of maintenance. Siemens standardized systems al- low simple integration for different requirement. Whether for the raw mill, kiln, belt conveyer or fine mill- ing, it is important to select the correct drive model and dimensioning to achieve uninterrupted and energy-effi- cient operation. The SICEMENT Drive Solutions portfolio includes specific drive solutions for all normal cement production processes. Despite the wide power spectrum, standardization allows them to be completely incorporat- ed into an integrated power supply network and control system. This is vital to guarantee safe and transparent operation of processes throughout the cement plant. www.industry.siemens.com 6. Replacement Parts Do you need more durable replacement parts? Replace- ment wear parts from Columbia Steel such as tires, grind- ing ring segments, armor rings and spindle shields are cast from high chromium alloy irons and fully heat treated for optimum mechanical properties.
