MODSIM™
|
MODULAR SIMULATOR
for
MINERAL PROCESSING PLANTS
MODSIM is now Open Source. Check our MODSIM GitHub repository. Be part of our development team.

USER-FRIENDLY FLOWSHEET EDITOR

Simulation starts with the definition of the
flowsheet which is drawn initially on the monitor using a specialized
graphics editor.
The graphic editor has an extensive array of icons representing all the
mineral processing unit operations encountered in practice.
The editor also allows for quick modification of the flowsheet structure and
replacement of existing units.
DATA SPECIFICATION

Data required to simulate processing plants describe
the characteristics of the material treated, the production rates targeted,
and the details of the unit operations included in the flowsheet. The
processing units are described by their physical characteristics and the
parameters of the mathematical models that describe the operation of the
physical equipment.
MODSIM™ is based on the population balance
method and is therefore capable of accounting accurately for variations in
particle size and mineral liberation characteristics together with other
critical properties such as density, mineralogical texture, elemental
composition, magnetic susceptibility, energy content, etc. Data structures
incorporate mineral and coal processing flowsheets.
INTEGRATED FLOWSHEETS

MODSIM™ simulates integrated flowsheets that
can include:
- crushing (jaw, giratory and cone
crushers, high pressure rolls)
- grinding (AG, SAG, Rod and Ball mills)
- classification (screens and hydrocyclones)
- flotation
- gravity separation (jigs, tables, cones, sluices, dense
medium vessels and cyclones, water only cyclones)
- magnetic separation (dry and wet drum separators and wet
high intensity separators)
- solid liquid separation (thickeners, dewatering screens and
filters).
MODELS

A wide array of models for the unit operations is
supplied. In most cases alternative models are available so that the user can
investigate the differences between various models of the same unit.
Most of the significant models available from the scientific literature are
included. Each model comes with a set of realistic default parameters.
User-specified models for any unit can be incorporated easily. Model
selection is fully interactive so models can be changed with a simple mouse
click.
DATA OUTPUT
 
Graphical, tabular and text outputs display simulation results quickly and
clearly. All output can be copied and pasted on most word processors for
convenient and effective report production.
Graphics can be exported as Encapsulated PostScript (.EPS) or Windows
Metafile (.WMF).

flowsheet.
MODSIM™ offers a unique and powerful ability to simulate mineral
liberation:
- Implements the complete Andrews-Mika liberation modeling in
Ball and Rod mills.
- Directly imports mineral liberation data from SEM or optical
microscopes through the MMIA™ and StereoSoft™
image analysis and stereological transformation software.
-
BENEFITS

- MODSIM™ powerful and versatile capabilities make it
the perfect computer simulation tool for quarry operators, coal
processors, base metal and industrial mineral producers, consultants and
