Upgrading the Ramilya plant only required a change in cross bars and the hydraulic system – a simple and quick process. With the upgraded transport mechanism, a shuttle drive motion is used that makes all of the cross bars move forward together while alternative lanes of newly designed two-wide cross bars move together in the reverse stroke. Each cross bar covers only two grates instead of four, making it possible to achieve more finite control across the width of the cooler. And while the SF cooler normally has six moving and six stationary cross bars, the upgrade has only six moving cross bars along the length of a module.

The result: increased clinker transport efficiency, allowing greater throughput and more control of the clinker bed under heavily loaded conditions – all with fewer wear parts.
