(PDF) Control of ball mill grinding circuit using model

Control studies have been performed by simulation for servo and regulatory problems. Limited studies for robustness of the controller have also been performed. Process descriptionThe laboratory grinding circuit consists of an overflow type ball mill (30 cm 30 cm), a sump fitted with a variable speed pump and a hydrocyclone classifier (30 mm).

operations namely cascading at a low speed of 65% and cataracting at higher speed of 75%. The higher speed generated the least pebbles. Keywords: Attainable region, semi-autogenous mill, ball mill, SABC circuit optimisation, pebbles, MODSIM

simulation as well as existing plant data to design full-scale ball mill circuits. Sosa-Blanco et al. (2000) develop a simulation model for tuning grinding circuit a with the objective of optimizing a flotation plant. Another simulation of a grinding plant is conducted in Duarte et al. (2002), in which

proposed flowsheet consists of existing SAG mill circuit followed by a new proposed ball mill in closed circuit with the existing hydrocyclone package. In all simulations, SAGT, CYCL and MILL models were selected to simulate SAG mill, Hydrocyclone packages and ball mill units. SAGT and MILL models both are based on the population balance model

In other words, the two existing parallel ball mills would be converted to an operation in series. Simulation 6 was based on the changes included in Simulation 5. Simulation 6 results showed 1050 t/h circuit throughput, yielding 0.213 mm and 0.138 mm P 80 values respectively at first and second ball milling stage discharges.

for ball mill operation based on the population balance It is our intention to explore the techniques of dy- modelling approach, with the assumption that mill namic simulation used in other industries (under the dynamics can be modelled by a number of perfect mixers MATLAB/SIMULINK environment) for development in series (see, Whiten, 1974

The grinding operation in a ball mill is widely used in comminution. This process is extremely capital and energy intensive process and at the same time it is notoriously inefficient. Therefore, simulation can be used as a convenient tool in studying the behaviour and performance of grinding circuits by facilitating the evaluation of various scenarios and identification of optimum operating

The experiment process is that the operators control the value of three grinding variables to achieve a target grinding particle size (GPS) on the ball mill grinding circuit simulator (see Figure

for a particular input and output of a ball mill. The variables for the ball mill include the ball density (in gm/cm3), ball diameter (in meter), belly length (in meter), mill diameter (in meter), volume of balls (in %), and rotation speed (in RPM). After making all the changes, the
