About GREMAC
GREMAC is a manufacturer of mobile trommel screening plants headquartered in Grasbrunn near Munich. The screening machines separate bulk materials such as soil, topsoil, compost, construction debris, recycling material, wood chips, excavated soil, asphalt, gravel, grit, cable sand, slag and plastic granulate by grain size – in a continuous work step via a rotating screening drum with an integrated conveying screw. The plants are manufactured in Germany and built with hot-dip galvanized components in a robust, modular design; they can be deployed as trailers, on hook-lift frames, with tracked undercarriage, or as stationary units. The model range extends from the compact entry-level machine eZero to the large-scale e3 plant with screening areas of 6.2 to 17 m² and capacities of under 50 to under 120 m³/h. In addition to sales and rental (daily, weekly and monthly rentals via more than 100 rental partners in the DACH region), GREMAC offers service, personal consulting, a test site at COREUM, and delivery through a Germany-wide dealer network. Its main industries of application are recycling, construction, landscaping and gardening, composting as well as demolition and bulk material processing.
