Our Products

Organic Waste Separation Particle Size Reduction Dust Explosion Protection Feeders Measuring & Screening

Take Advantage of More than 66 Years of Experience

We have been developing, designing, and producing hammer mills and grinding technology in Germany since 1959. Since 2007, this has also included the processing and separation of substrates for biogas production. Complex customer requirements are our specialty: from the first contact to the delivery of the optimum system and after-sales service, we are your competent partner for the processing of your biomass.

We ensure that your resources are optimally used – worldwide
