1 Scope

This standard specifies the terminology and definition of the test method for the application of the vertical mill, the test conditions, the test system equipment and the apparatus, the test content And procedures, test system calibration and test report, to provide the basis for vertical mill selection. This standard applies to grinding cement raw materials, cement clinker and granulated slag grinding mill system.

2 terms and definitions

The following terms and definitions apply to this document. 2.1 Test yield GP The quality of the product obtained with the determined particle size or specific surface area obtained during the unit time. Note. The unit is kilograms per hour (kg/h). 2.2 Test stand-alone production power consumption experimentalmilproductpowerconsumption Test the power consumed by the mill at the unit mass (at the coupling end). Note. The unit is kWh per ton (kW · h/t). 2.3 Relative Grindability Index relativegrindabilityfactor KM The ratio of the unit power output of the test piece to the standard material unit productivity. The value is large, indicating that the material is easy to grind. 2.4 Wear wearsswearandconsumption Quality of the unit consumes the quality of the wear of the wear piece (disc liner and roller set). Note. The unit is grams per ton (g/t).
