ball mill circuit operation simulation

Spreadsheet-based simulation of closed ball milling circuits

For example to simulate a tumbling ball mill in an open circuit, the corresponding button, No. 1, must be selected and pressed. Then, automatically another spreadsheet will be opened to enter simulation data (Figs. 2 and 3). One important question asked by the program is the number of screens used to define the particle size range.

MODELLING AND SIMULATION OF THE GRINDING CIRCUIT

The grinding operation in a ball mill is widely used in comminution. However, this process is extremely capital and energy intensive process and at the same time it is notoriously inefficient. Therefore, accurate designing of both circuit and operating parameters are important to optimise the power consumption, which can lead to substantial economic benefit. Simulation can be used as a ...
