May 10, 2019 For example, consider a 100 KPPH (45360 kg/hr) pulverizer which was designed for a Hardgrove Grindability Index (HGI) of 60, a surface moisture of less than 10%, and a feed size of 2.5. The 100 KPPH (45.36 T/hr) rating means that operating at those stated conditions the pulverizer product will have a fineness of 70% through a 200 mesh at a throughput of 45.36 TPH.
