1 The drive solution supplied by Siemens corresponds to the principle of the Integrated Drive System (IDS). Fluid couplings are used to dampen impacts occurring in heavy-duty everyday use which could damage the gear and crusher rolls

2 The compact design of the H3SH helical gear from Siemens allowed a center distance of just 850 millimeters to be achieved between the rolls

Hazemag & EPR GmbH (Hazemag) based in Dülmen is among the leaders when it comes to the construction of crushing plants. For the retrofit of a limestone crushing facility in France, Hazemag developed the Hazemag Center Sizer HCS 1020 with two counter-rotating rolls. For the drive, the company used Integrated Drive Systems (IDS) including two helical gears from Siemens. The major benefit of this solution is the combination of standard components and individual elements which simplifies both maintenance and engineering, as well as cutting delivery times.

When it comes to crushing plants for the industrial treatment of primary and secondary raw materials, the specialists at Hazemag & EPR GmbH (Hazemag) based in Dülmen, southwest of Münster in Germany, can draw on experience gathered over a 170-year long company history.
