A proper model is an invaluable tool for circuit optimization. Depending on your needs, a variety of software can be used for steady-state or dynamic simulation of comminution circuits. Modeling and simulation also provide information to help select the best equipment and plant layouts during new circuit …
A typical mineral comminution circuit includes a ball mill running in closed-loop with a hydrocyclone battery. The job of the grind circuit is to reduce the size of the ore such that the downstream separation process can achieve the desired mineral recovery and quality while maintaining plant throughput and cost efficiency targets.
6 Comminution circuits Energy efficient circuits – solving the puzzle To be energy efficient, a circuit needs not only to have the right equipment but have that equip-ment optimized. Even the most efficient equipment installed on the wrong application will not be energy efficient. Our expertise extends the supply of single unit
