It’s vital that raw materials are handled, treated, and conditioned in a way that achieves optimum furnace operation. This is where SMS offers a wide variety of systems. You can choose from various setups for all the required facilities, for example:

  • Unloading stations for trucks, trains, and vessels
  • Stock yard systems, e.g. stacker reclaimer systems
  • Material preparation, such as washing, sorting, screening, drying, agglomeration, and separation
  • (Day) storage systems
  • Highly accurate batch or continuous composition of burden mix
  • Conveying systems for all facilities

Most applications in this area involve casting SAF melt into solid blocks. Then these blocks need further treatment to meet the requirements for products such as bulk or powder material in defined sizes. SMS offers a range of systems for conditioning cast products:

  • Crushing, grinding, and milling stations
  • Sorting, screening, and sizing systems
  • Blending, grain spectrum confectioning, and portioning facilities
  • Agglomeration and densification facilities
  • Packing facilities, e.g. for big bags, plastic bags, cardboard cartons
  • Loading systems for dump trucks, silo trucks, train wagons, and sea containers
