Feb 17, 2018 The empirical approach to grinding modelling and control presents also some implementation difficulties. First of all since the process model unavoidly changes with time, it must be estimated by adaptive methods such as it is in self-tuning controllers. Second the MV controller requires the knowledge of the
The simulator implements the dynamic ball mill grinding model which formulates the dynamic responses of the process variables and the product particle size
Jan 17, 2014 Modeling and Simulation of Whole Ball Mill Grinding Plant for Integrated Control. Abstract This paper introduces the development and implementation of a ball mill grinding circuit simulator, NEUSimMill. Compared to the existing simulators in this field which focus on process flowsheeting, NEUSimMill is designed to be used for the test and verification of grinding process control
The modeling results were in very good agreement with the particle size distributions obtained after grinding the feeds in a ball mill. The mechanistic approach has proven so far to be flexible and successful for simulation of the grinding process.

Aug 01, 2008 Ball mill grinding is a fundamental operation process, and in many respects the most important unit operation in a mineral processing plant. Grinding process represents almost half of the total operating costs associated with the mining operation, and the product particle size greatly influences the recovery rate of the valuable minerals and ...
Apr 17, 2018 The inferred particle size model is a key part of the grinding control system presently being used. The model, as used during the evaluation period, related the percent 65 mesh material in the cyclone overflow to three of the mill operating variables ball mill feed, mass flow of ore to the cyclones, and mass flow of water to the cyclones.
That does not mean that the preference is speed control over feed rate control. Each ore is different and each plant is different. As equipment designers, we have to provide each of the features that the operators could use to optimize their process. In my experience, SAG Mills are normally variable speed, and Ball Mills are normally fixed speed.
