How it works
The key change involves an upgraded transport mechanism. A shuttle drive motion is used, where all cross bars move forward together, and alternative lanes of newly designed 2-wide cross bars move together in the reverse stroke.
Because each cross bar covers only 2 grates instead of 4, you achieve more finite control across the width of the cooler. Furthermore, while your existing SF cooler has 6 moving and 6 stationary cross bars, the upgrade has only 6 moving cross bars along the length of a module.
In practice, this requires changing the cross bars and dividing the drive frame into 2 separate, independent drive plates. By increasing the clinker transport efficiency with the same hydraulic flow volume and with fewer strokes, you achieve greater throughput without enlarging the grate area. And since the drive now moves more slowly, the lifetime of wear parts is also extended.
