Dust-free spreading of binding agents

Dust-free construction processes with the integrated ‘S-Pack’ binding agent spreader module

The purpose of the ‘S-Pack’ (Spreader Pack) module factory-installed in WR 240(i) or WR 250(i) machines, or integrated as an optional extra in other models, is to enable dust-free spreading of binding agents during cold recycling and soil stabilisation. It spreads lime or cement directly in front of the milling and mixing rotor in a microprocessor-controlled process. ‘S-Pack’ stands for reliable and as good as dust-free spreading of binding agents, which is particularly important on motorways, on industrial estates with strict emission requirements, in residential areas or in nature reserves.

Precise metering systems for binder addition

Precise and almost dust-free spreading of binding agents, regardless of wind and weather conditions.

The spreader can be filled to capacity in less than five minutes. The ‘S-Pack’ can get through the full load of a standard 27-tonne silo semi-trailer within the space of two hours. The standard control panel in the machine operator’s cabin enables intuitive control and monitoring of the spreading process.
