Summary: A jaw crusher in France for the comminution of ROM limestone has been replaced with a new Center Sizer solution in the context of a retrofit project. Not only the comminution rolls, but also, and above all, the gearing-system solution, are worthy of note. The reason: the gearing supplier combined standard technology with individual elements.

Comminution processes play a central role in the industrial-scale preparation of primary and secondary mineral resources. Hazemag & EPR GmbH, based in Dülmen, to the south-west of Münster and possessing more than 170 years of corporate history, is one of the top addresses for high-quality comminution machines. Not only the comminution rolls, but also, and above all, the drive systems, are challenges, as is illustrated by the example of a retrofit project for limestone comminution in France. As Jochen Emmerich, responsible for Center Sizer crushers at Hazemag & EPR GmbH, affirms, “Whenever a...
