an ore grinding process within a mineral processing plant. To do this, we use a simulation model of the grinding process that has been calibrated on real operational data. The model is implemented in the popular industrial simulation software Dymola [10] which is based on the Modelica [11] language.
This paper describes the simulation of the grinding process in vertical roller mills. It is based on actual experimental data obtained on a production line at the plant and from lab experiments. Sampling and experiments were also carried out in a power plant that has four ballmill circuits used for coal grinding so that different equipment ...
This work concentrates on the energy consumption and grinding energy efficiency of a laboratory vertical roller mill (VRM) under various operating parameters. For design of experiments (DOE), the response surface method (RSM) was employed with the VRM experiments to systematically investigate the influence of operating parameters on the energy consumption and grinding energy efficiency.
Fig. 6 shows the closedloop grinding circuit of the SAG mill simulation. In this closed grinding circuit simulation, a simple and crude PID control is implemented to regulate the sump level to a constant (hence to prevent the sump from overflowing) by adjusting pump out rate of the sump alone (no changes to the water addition to the sump).
A dynamic nonlinear simulation model is fitted to the grind curves of a SAG mill. •. The model captures the shortterm dynamics of the grinding mill. •. The model represents the steadystate operating conditions of the grind curves. •. It offers a simulation platform to test controllers for all operating conditions.
1.. IntroductionGrinding is an essential step in the mineral processing industries. It has been the subject of research for almost 50 years. Over these years, a number of comprehensive review papers have been written to summarize the state of knowledge relating to the grinding theory and practice (see Austin, 1997, King, 1993).In spite of its economic importance and years of research, grinding ...

A rigorous analysis of disturbance rejection performance is given with the considerations of both model mismatches and external disturbances. Simulation results demonstrate that when controlling the ball mill grinding circuit, the DOBMPC method possesses a better performance in disturbance rejection than that of the MPC method.

2. Background. The SAG grinding process has been modeled by various authors, either generating explanatory models of the grinding process, with the aim of modeling, simulating, and optimizing the individual process, as well as integrating it into aggregate processes, such as the minetomill (M2M) paradigm, a practice that has generated the capacity to analytically assess aspects of mining and ...
In this paper, COMSIM, a new simulator which runs under Excel spreadsheet will be introduced which uses a Population Balance Model (PBM) to simulate ball mills. Plitt and Nageswararao models have been used to describe the performance of hydrocyclones, which by linking to the ball mill model allow for closedcircuit simulations.

In a mining operation grinding mill power draw is an essential operating parameter since the energy spent in milling the ore contributes significantly to the cost metal production. Besides, the energy spent per ton of processed in the mill influences the degree of size reduction in the mill.
The FluentDEM cosimulation method is used for the study of the complex physical field of mill operation. The simulation shows that grinding efficiency increases with spindle speed, but the increase from 110 to 120 rev/min is not significant, so the choice of spindle speed should consider both grinding efficiency and energy consumption.
