1. Overview

DPSIM Static Module represents a mineral processing circuit as a flowsheet. The flowsheet contains equipment, called unit operations, connected by streams. Each stream carries material information such as solids flowrate, water flowrate, particle-size distribution and component content. Each unit operation applies a mathematical model to transform one or more input streams into one or more output streams.

FlowsheetThe visual representation of the plant or circuit. It shows the order in which material moves through feeders, crushers, mills, classifiers, separators, dewatering units and final products.

StreamThe material connection between two units. Streams store input data for feeds and simulated data for calculated products.

Unit operationAn equipment item placed on the flowsheet. Examples include feeders, crushers, ball mills, screens, hydrocyclones, flotation cells, thickeners, filters, mixers and splitters.

ModelThe calculation method used by a unit operation. Model parameters control how the selected equipment transforms the incoming material.

The static simulator solves the steady-state material balance for the circuit. It does not describe how the plant changes second by second; instead, it calculates the operating point associated with the current feed data, model parameters and flowsheet connections.

2. First Launch and Project Files

When DPSIM Static Module opens, the main workspace displays an example flowsheet with mineral processing units, streams, recycles and product streams.

4. Project Setup

Configure the particle-size mesh and component list before entering detailed feed data or model parameters.

Particle-size mesh

The particle-size mesh defines the size intervals used by stream granulometry and by size-dependent models. Enter the size classes in descending order and keep the final pan interval at zero. Once the mesh is set, all stream size distributions use the same interval structure.

DPSIM Static Module default stream size classes dialog — The Default Stream Size Classes dialog defines the project granulometry mesh in micrometers and millimeters. The size classes should be edited in descending order.

Changing the particle-size mesh after feed data has been entered can invalidate size-distribution tables and model inputs. Set the mesh early, then keep it stable while building the simulation case.

Components

Components represent the mineral, chemical or material constituents tracked through the flowsheet. They are used for grade, assay and component-by-size calculations. Use clear names that match the plant study basis, such as Fe, SiO2, Cu, valuable mineral, gangue or other project-specific components.

Setup item	Recommendation	Reason
Size intervals	Use the same mesh as laboratory or plant PSD data when possible.	Reduces interpolation and makes model calibration easier.
Pan interval	Keep the last interval at zero.	Represents material below the finest sieve size.
Component names	Use short and consistent names.	Improves readability in stream tables and reports.
Component order	Keep the list stable after entering data.	Avoids confusion when comparing component columns across streams.

Practical setup sequence

Define the project particle-size mesh.
Define the component list.
Add feed units and enter feed stream data.
Add unit operations and connect streams.
Configure model parameters.
Run the static simulation and review results.

5. Working with the Flowsheet

The flowsheet canvas is the main workspace for building a circuit. Unit operations are added from model palettes, positioned on the canvas and connected with streams.

Adding units

Use the toolbar model categories to add equipment. The Static Module includes Feed, Comminution, Classification, Concentration, Dewatering and Auxiliary models for steady-state simulation.

Category	Typical models	Purpose
Feed	Editable Product Stream Feed, Water Feed, Density Regulator, Component PSD Feeder	Introduce solids, water, size distribution and component information into the circuit.
Comminution	Crushers, ball mills, rod mills, vertical mills, HPGR and energy-based comminution models	Represent size reduction and associated power or product-size behavior.
Classification	Screens, hydrocyclones and partition models	Split material by size or component partition behavior.
Concentration	Flotation and component recovery models	Separate valuable and non-valuable material using grade/recovery behavior.
Dewatering	Static thickener and filter models	Adjust water content and solids concentration.
Auxiliary	Mixer, splitter, static stockpile and related support units	Combine, divide or terminate streams in the flowsheet.

Connecting streams

Streams connect output ports to input ports. A unit may have one or more input/output ports depending on the model. When a stream is connected, it becomes part of the calculation path used by the static solver.

Add the upstream and downstream units to the flowsheet.
Use the available ports to create a stream connection from the upstream output to the downstream input.
Adjust the stream path if the drawing needs a cleaner route.
Run the static simulation and confirm that the calculated stream appears in the result panels.

Layout tools

Use zoom, grid display, snap to grid, label visibility and flyouts to keep the circuit readable. Lock the canvas during result review to prevent accidental movement of equipment or streams.

6. Streams and Material Data

Streams carry the material state between unit operations. Feed streams usually contain user input data. Downstream streams are calculated by the simulator after a static run.

DPSIM Static Module with a stream selected and stream data tabs visible — Selecting a stream displays stream input or simulated data in the upper inspector panel.

Stream properties

Property	Description	How to use it
Solids flowrate	Dry solids mass flow through the stream.	Use for mass-balance checks and equipment loading.
Water flowrate	Water associated with the stream.	Use for water-balance review and pulp density checks.
Pulp/slurry flow	Total stream including solids and water.	Use when comparing hydraulic loading or slurry handling.
Percent solids	Solids concentration in the stream.	Use to confirm whether process streams are realistic for the equipment.
Particle-size distribution	Mass distribution across the project size mesh.	Use to compare feed, product and classification performance.
Components	Component grades or fractions, optionally by size class.	Use for grade/recovery and metallurgical balance review.

Input data versus simulated data

Use the input data tabs to define feed streams. The simulated data tabs show calculated values after a static run. If a downstream stream has no results, check the upstream data, model parameters and stream connections.

Graph views

Stream graphs help compare size-distribution curves. Use them to check whether comminution, screening, hydrocyclone or partition behavior is producing a plausible product. If a graph appears blank, verify that the stream has simulated size-distribution data and that the graph series are visible.

DPSIM Static Module stream size distribution graph window — The stream size-distribution graph compares selected granulometry curves and can be used to inspect feed, product and intermediate streams.

7. Unit Operation Models

Every process unit uses a model to convert input streams into output streams. Configure and review the model in its equipment panel; equations and model-specific assumptions are documented in the DPSIM Models Reference.

DPSIM Static Module with equipment selected and model parameters visible — When equipment is selected, the lower inspector panel shows model parameters, calculated parameters and detailed output tabs.

Model panel tabs

Tab or area	Purpose	Review practice
Model parameters	User-controlled model inputs.	Check units, default values and calibration basis before running scenarios.
Calculated parameters	Values derived from user inputs or the current simulation.	Use to check intermediate calculations such as power, split or capacity-related values.
Detailed output	Model-specific calculated tables or diagnostics.	Use when reviewing why a unit produced a particular result.
Reports/export tabs	Model documentation, validation and calculation details where available.	Use for engineering review or for documenting assumptions.

Configuration examples

A comminution model typically needs parameters that describe the equipment size, operating condition, energy input or breakage behavior. A classification model typically needs parameters for cut size, efficiency or partition behavior. Auxiliary models such as mixers and splitters handle stream combination, stream division and flowsheet routing.

Check parameter definitions, equations and model-specific assumptions in the Models Reference before interpreting results.

Equipment report views

The report preview windows summarize equipment configuration and calculated values. Use them to check model setup or transfer model information to an engineering note.

Pre-run checklist

The particle-size mesh and component list are defined.
Feed streams contain solids, water, size distribution and component data as required.
All intended equipment is connected by streams.
Each unit operation has a suitable model and realistic parameter values.
Recycle or split/mix structures are connected intentionally.
Static simulation iteration count is appropriate for the circuit complexity.

Iteration settings

The Static Simulation Iterations setting controls how many calculation passes the solver may perform. Simple circuits may solve quickly with a small number of iterations. Circuits with recycles or stronger interdependencies may need a larger limit, such as 100 or 1000 iterations.

DPSIM Static Module settings dialog showing static simulation iterations — The Settings dialog includes the Static simulation iterations control used by the static solver.

After the run

After a successful run, inspect the stream data, calculated equipment parameters and Results Sheet. For unexpected results, review the feed data first, followed by the connections and model parameters.

9. Results and Engineering Review

Review stream data, equipment results and the overall mass balance together. A single stream or graph is not sufficient to assess the flowsheet.

Stream Results Sheet

The Stream Results Sheet is a spreadsheet-style review window. It can load stream results, run the static simulation and load results, export CSV, copy data to the clipboard, select all, clear the grid and customize displayed lines and columns.

11. Example Tutorial Using the Startup Circuit

Use the startup circuit as a guided example of data flow through DPSIM. Its values are illustrative and require calibration before use in an engineering decision.

Open DPSIM Static Module and review the startup flowsheet.
Identify the feed units, comminution section, classification section, recirculating streams and final product streams.
Select a feed stream and review solids flow, water flow, size distribution and component data.
Select a crusher or mill and review the model parameters.
Select a screen, hydrocyclone or partition unit and review classification parameters.
Run the static simulation.
Open the Stream Results Sheet and load all streams.
Compare the main feed, circulating load, product and tailings streams.
Check whether the product size distribution and component grades are plausible for the intended example.
Save a copy before changing parameters for scenario comparison.

After the walkthrough, change one operating parameter at a time, rerun the static simulation and compare the Results Sheet to observe its effect on the circuit balance.

12. Troubleshooting and Best Practices

Symptom	Likely cause	Action
No result appears for a stream.	The stream is not connected, the upstream unit has missing data, or the simulation has not been run.	Check connections, feed data and model parameters, then rerun the static simulation.
Size-distribution graph is blank.	The stream has no simulated granulometry or graph series visibility is not enabled.	Select the relevant stream, confirm simulated size data exists and review graph series settings.
Results look physically unrealistic.	Feed data, water data, component data or model parameters may be inconsistent.	Start from feed streams and work downstream, checking one unit at a time.
Circuit is hard to read.	Equipment and streams are not aligned or labels/flyouts are cluttered.	Use grid, snap to grid, zoom, label visibility and alignment tools.
Changing project mesh caused data loss.	Project mesh changes affect all streams.	Set mesh before detailed data entry and save a backup before changing it.
Simulation does not stabilize as expected.	Recycle structure or model settings may require more iterations or better initial data.	Increase static iteration count and inspect recycle-connected units for unrealistic parameters.

Best practices

Keep project files organized by scenario.
Use clear stream and equipment names.
Document assumptions outside the model when preparing engineering deliverables.
Review both stream-level and unit-level results.
Use the Models Reference whenever a parameter meaning is not obvious.
