Effects of Blade Parameters on the Flow Field and Hindawi

The vertical roller mill is an important crushing and grading screening device widely used in many industries. Its classification efficiency and the pressure difference determine the entire producing capacity and power consumption, respectively, which makes them the two key indicators describing the mill performance. Based on the While the data were evaluated within the scope of energy-size reduction relationship for vertical roller mills, Morrell’s equation (Morrell, 2004) was based on. The K parameter for present data was back calculated and a preliminary energy-size relationship was developed to predict the grinding energy of the vertical roller mill.Predicting the grinding energy of vrm depending on material
