About Maschinenfabrik Gustav Eirich
Maschinenfabrik Gustav Eirich GmbH & Co KG is a family company founded in 1863, headquartered in Hardheim (Baden-Württemberg) and the strategic center of the EIRICH Group with 15 locations worldwide. The company develops, manufactures and sells machines and systems for processing technology: mixing technology, granulating/pelletizing, drying and fine grinding – from laboratory mixers (0.1–10 l) and small-scale mixers (40–150 l) up to large-scale mixers (250–12,000 l). Core competence is processes for the preparation of bulk solids, suspensions and slurrys; well-known brands include MaxxMill, Evactherm, Evacmix, Saponiflex, Eikorit and Eidurit. The offering also includes control and measurement technology (QualiMaster AT1, SandExpert, ProView), an in-house test center for trials with customer raw materials, service, teleservice, condition monitoring and spare parts. Applications range from building materials, ceramics, glass and foundry molding sand to battery masses, friction linings, metallurgy and fertilizers through to environmental technology. Around 550 employees work in Hardheim and Külsheim, and the group comprises approx. 1,500 employees in 12 companies in 11 countries.

Processes and Processing Technology
Mixing (intensive mixers)
Homogenizing, coating, kneading, dispersing and cooling of bulk solids, suspensions and slurrys in sizes from 0.1 to 12,000 liters.
Granulating/Pelletizing
Agglomerating and pelletizing e.g. of filter dusts, ashes and fertilizer raw materials to improve handling and recycling.
Drying (Evactherm®, Evacmix®)
Drying and conditioning of slurrys, filter cakes and lumpy materials, often without separate auxiliary units.
Fine grinding (MaxxMill)
Agitated media mill for dry and wet grinding for fine comminution in various industries.
Injection Molding Compound Preparation
Production of injection molding compounds e.g. for sintered metal, carbide and fiber-reinforced ceramics by homogenizing, coating, kneading and dispersing.
Molding Sand Preparation
Preparation of clay-bonded molding sand boxes with QualiMaster AT1 inline tester and SandExpert for stable foundry processes.
Technikum/Test Center
Trials with customer raw materials, process development, system design and rental machines for in-line or bypass tests.
