    A Direct Approach Of Modeling Batch Grinding In Ball Mills

    A direct approach of modeling batch grinding in ball mills.The design and scale-up of ball mills are important issues in the mineral processing industry. Incomplete knowledge about the mechanics of charge motion often forces researchers to rely on phenomenological modeling to formulate scale-up procedures. These models predict the behavior of large industrial-scale mills using the data obtained in small laboratory-scale mills. However, the differences

    How Slurry Transport Inside A Tumbling Grinding Mills

    How Slurry Transport inside a Tumbling Grinding Mills.May 24, 2018 The transport of slurry within the ball mill depends on the peripheral velocity and porosity of the ball charge. Residence time distribution and mill hold up are often used as indicators of the mode of transport. In this work, the transport problem is tackled via direct simulation of the three dimensional motion of the ball charge.
