Program Specifications

ROCKY is currently available in three packages: Basic, Designer, and Professional. Each package contains the following features:

• Streamlined calculations
• Double precision processing
• Realistic-looking particle shapes
• Large particle size distributions (greater than 25:1)
• Wet and dry contact rheologies (sticky particles)
• Easy CAD geometry import and simulation setup
• Animated and vibrating boundaries
• Batch processing for multiple simulations
• 360° wraparound movie view transitions
• Graphical and at-a-glance wear and power data

In addition, some ROCKY packages contain the following additional features:

• Six degrees of freedom (6df) is the ability for a boundary to move in response to particle, forces and/or moments rather than following a programmed path.
• Energy spectrum is the collection of the particles' collision energy statistics (normal and tangential). This is useful for evaluating the particles' breakage/attrition rates.
• Periodic boundaries simulate infinite length conditions in one direction with a slice of geometry. This is useful for simulating mills, for example: objects pass through one side of the mill slice and reappear on the slice's opposite plane.
• Surface wear modification enables modification of a geometry's surface due to shear work applied by particles. (Requires calibration.)
• Analysis boxes provide the ability to place a box in the simulation and analyze particle parameters (mass, velocity, etc.) in this box only. Useful for counting the number of particles coming off a vibrating screen, for example.

ROCKY Simulation Types

Besides chute and mill designs, you can use ROCKY to evaluate all of the following types of materials handling systems:

• plugged chutes
• belt and apron feeders
• vibrating feeders
• bins and bunkers
• stockpile reclaims
• moving gates
• rod mills
• screw conveyors
• and much more!

Data Input Types

ROCKY enables geometry import of XGL, STL, and DXF files, which can be exported from CAD programs such as Autodesk Inventor and AutoCAD.
