the market - in terms of upfront investment, technical design and long-term cost of ownership. The FL Smidth Cross-Bar cooler replaces previous Cross-Bar cooler version to become FL Smidth's one cooler offering for both new installations and upgrades. Benefits of the FL Smidth Cross-Bar cooler The cooler uniquely provides a number of key benefits - something that no other cooler on the market today can fully demonstrate all at the same time. • Consistently high thermal efficiency • High reliability and availability • Fast, low cost installation • Low, predictable maintenance The features that support above benefits are: • Separate clinker conveying and cooling systems - Crossbars effectively convey, mix and shear the clinker. Wear of crossbars has no effect on thermal efficiency of cooler • A stationary, sealed grate line ensures no fall through and no requirement of under grate clinker conveying system • Self-adjusting mechanical flow regulators (MFRs) maintains constant air fl ow through air distribution plane and clinker bed without operator intervention results in stable cooler operation and high thermal efficiency • Horizontal design with optimized transport method. • Modular concept: The FL Smidth Cross-Bar Cooler can be supplied for new coolers as well as to upgrade exiting coolers. Each unit measures 1.2 or 1.8 metres in width and 3.0 or 4.2 metres in length. Standard units are preassembled in workshop to ensure high quality and swift and simple installation. To form a whole cooler, a number of units are put together length-wise and width wise and the moveable frames are connected along the length of the cooler. • Cooler drive Fast and low cost installation as hydraulic cylinders is integral to CB units. Each movable frame operated by two or four hydraulic chamber. No hydraulic components in first under grate chamber. Each drive has a separate motor and pump unit in closed loop system. FL Smidth's innovative and technological leadership is again demonstrated with the introduction of the new FL Smidth Cross-Bar cooler. Should one lane be taken out of operation, remaining movable frames can be kept in operation without stopping the cooler. • The cooler is erected on simple horizontal line foundation/support structure. • Access passages FL Smidth Cross-Bar cooler has standard above-ground access passage across the cooler width which helps in monitoring under grate components during operation and provided outside access to the bearing lubrication points. • Maintenance The cooler has very few wear parts for easy and economical maintenance. 19
