Schmutz + Hartmann AG
About
Schmutz + Hartmann AG, based in Ormalingen, Switzerland, is a specialized manufacturer of conveying solutions for environmental technology applications across wastewater, biogas, and waste management sectors. The company's product line centers on two core technologies: seamless spiral conveyors and custom screw conveyors. Their spiral conveyors, manufactured entirely in-house at Ormalingen, range from 30 mm to 720 mm in diameter and are available in steel and stainless steel with optional wear protection, with standard spirals ready to ship within one day. Beyond basic conveying, Schmutz + Hartmann builds press conveyors that simultaneously transport and compress biomass, and fermenter-input systems designed to feed biomass into anaerobic digesters at multiple levels. Their collector bins feature configurable spiral floors, auger floors, or sliding-ladder floors for material receiving and distribution. Custom funnels and purpose-built conveying and mixing machines are developed collaboratively with customers for specialized applications. The company provides full-lifecycle support from initial consultation through engineering design, in-house welding and production, installation and commissioning, to ongoing customer service. A rental conveyor program covers temporary or project-based needs. Their systems handle mud, sand, biomass, gravel, and powder, with specialized designs for long-fiber materials that would clog conventional equipment.
