The Ammann Single-Shaft Compulsory Mixer CEM S Elba is about efficiency and time savings in a variety of settings. The mixer, with double spiral, has a compact design that reduces the length of material movement. The shorter distance combines with an optimal tool arrangement for fast mixing times.

The mixers can provide capacities from 0.5 m³ to 2.66 m³ of compacted fresh concrete per batch. The CEM 60 S Elba, with a mixing volume of 60 liters, is ideally suited for concrete development and laboratory applications as well as for universities.

Depending on the mixer’s size, the Ammann mixer processes grain sizes up to 180 mm. Mixed materials in the single-shaft compulsory mixer are not separated by horizontal centrifugal separation.
