If you use jet mills for the production of ultra-fine powders, you can save energy costs by cleverly utilising heat from the compressed air. KAESER has expanded the range of options for its oil-free screw compressors in the CSG, DSG and FSG series for this purpose.
Besides stream, jet mills are mostly operated with compressed air or with nitrogen in the circuit. When converting the energy in the grinding nozzles, not only the pressure but also to a rlage extent the heat stored in the compressed air can be used for the grinding process. This waste heat is generated during the production of compressed air and is accordingly available free of charge.
