Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Continuous improvements are a key aspect of driving an industrial process plant at a profitable state. The performance of the crushing plant is driven by each equipment’s (crusher, screen conveyors, bin, etc.) operation, raw material properties, operational strategies, control system, maintenance, and so on. To bring improvements for full-scale industrial units, a thorough investigation is needed. In the considered case study, a need was posed by the industry operating coarse and fine comminution circuit to investigate the opportunities for upscaling and downscaling of the plant capacity along with evaluating the performance of the existing circuit. The need is driven by the change in ore characteristics from the mining segment. As the decision’s in the industry is driven by the cost, it is important to find opportunities which will increase the profitability and produces a viable solution(s). The paper presents a methodological approach for evaluating the performance of the crushing plant by carrying out: • Physical investigation and observation • Experimental survey and laboratory data analysis • Evaluating historical production data • Simulation configuration and calibration in Plantsmith process simulator • Evaluating alternative concepts using Plantsmith process simulator The evaluation presents possible improvements in the existing plants, and alternative concepts with their opportunities and pitfalls. The results show that a methodological approach can bring a wide understanding of the plant operations and simulation tool is useful for evaluating operational scenarios. Also, multiple practical aspects are presented concerning the investigation process.

- A comminution process is a material size reduction and separation process which is primarily used in the aggregates and the minerals processing industry. Knowledge related to equipment’s operation, raw material properties, operational strategies, control system, maintenance, etc. is needed to design a capable plant. New needs are arising from the industry for existing operational crushing plants such as investigation for improvements, upscaling, and downscaling of the capacity. The paper presents an application of simulation-driven development for a crushing plant in an existing gold processing plant. Due to the change in ore characteristics and the need for optimizing the cost of operation, it is required to investigate the opportunities for improvement and alternative options for downscaling the capacity of the plant. A systematic process for configuring, developing, and evaluating alternative concepts using a process simulation tool is presented. The results show the process of generating knowledge for alternative crushing plant operation settings and how the choices can be selected and eliminated using boundary conditions. The evaluation presents possible improvements and alternative concepts with their opportunities and pitfalls.
