DPSIM Models Reference

MINPRO Dynamic Simulator is a tool for process and control engineers focused on mining industry. The software combines mineral processing simulation with control features, enabling an enormous variety of applications, from static and dynamic simulations, control projects, training tools (OTS – Operators Training Simulation), etc.

The Component PSD Feeder model is a DPSIM feed source that builds the output feed stream from component-specific particle size distribution and grade parameters. The model creates an independent Rosin-Rammler-type cumulative passing curve for each project component, then combines the component curves into the final stream PSD and component-by-size matrix.

The unit receives a feed stream and regulates the output solid percentage by adding the required water flowrate.

The unit is intended to add a feed stream to the simulation through its output stream. The model has no parameter, the user should set the output stream parameters directly on stream interface.

The Available Power Comminution model is a comminution model that estimates product size distribution from the total available power applied to the feed stream. It calculates the specific energy from available power and feed solids flowrate, estimates a product P80 for each component using a generalized energy-size relationship, and then reconstructs the pro

The King Primary Crusher model estimates the product particle size distribution of primary jaw or gyratory crushers using the empirical formulation presented by R. P. King. The model is based on the crusher open-side setting and on a product type index that represents the material breakage characteristic.

This model represents the crushing through the breaking and classification functions as proposed by Whiten, W. J.; Walter, G. W.; White, M. E. (1979). A breakage function suitable for crusher models. IV Tewkesbury Symposium, Melbourne, pp. 19.1–19.3.

The Vendor Known Product Crusher model is an empirical crusher model that imposes a user-defined product size distribution on the crusher product stream. The model should be used when the crusher product PSD is known from vendor data, plant survey data, laboratory testwork, or a previously calibrated product curve.

The Modified Whiten Crusher model represents crushing through an internal classification function and a component-specific breakage matrix. The model is based on the Whiten crusher formulation originally proposed by Whiten, Walter and White in “A breakage function suitable for crusher models” Fourth Tewkesbury Symposium, Melbourne, 1979.

The Generic Matrix Crusher model represents crushing through an internal classification function and a generic breakage matrix. The model follows the matrix approach to breakage introduced by Broadbent and Callcott in “A matrix analysis of processes involving particle assemblies” Philosophical Transactions of the Royal Society of London, 1956, and uses the c

The Specific Energy Comminution model estimates the product size distribution from an imposed operating specific energy and component-specific Bond Work Index values. The model is based primarily on the Bond energy-size relationship originally proposed by Bond in “The third theory of comminution” Transactions AIME, 1952. The user-defined exponent allows the

The Known Product P80 Comminution model estimates the required power and product size distribution for a user-defined target product P80. The energy calculation is based on the Bond energy-size relationship originally proposed by Bond in “The third theory of comminution”, Transactions AIME, 1952. The product size distribution is reconstructed using a Rosin-R

The Plitt Original Hydrocyclone model represents hydrocyclone classification using the empirical model proposed by L. R. Plitt in “A Mathematical Model of the Hydrocyclone Classifier”, CIM Bulletin, December 1976. The model estimates corrected cut size, flow split, pressure drop, sharpness of separation and the particle-size partition to underflow.

The Plitt Modified Hydrocyclone Alpha is intended to provide a modified Plitt-family option to represents hydrocyclone classification using a modified empirical Plitt-family formulation. The model calculates pressure, volumetric split, corrected cut size, sharpness of separation, water bypass and the size-by-size partition to underflow.

The Plitt Hydrocyclone Bravo model represents hydrocyclone classification using an alternative Plitt-type empirical formulation. It calculates pressure, hydraulic head, volumetric split, corrected cut size, sharpness of separation, water bypass and size-by-size partition to underflow.

The Component Partition Separator model is an empirical classification model that splits a feed stream into coarse and fines products using component-specific partition curves. Each component has its own cut size, sharpness and bypass parameter.

The Ideal Size Partition model is a deterministic classification model that splits each component by a component-specific cut size. For each component, size classes coarser than the cut size report completely to the coarse stream, while size classes equal to or finer than the cut size report to the fines stream.

The Spline Partition model is an empirical component-specific separator that uses user-defined size-recovery points to build a partition curve for each component. For each component, the model fits a spline through five size-recovery points and uses the fitted curve to calculate the recovery of each size class to the concentrate stream.
