APPLICATIONS

Mining and manufacturing organizations all over the world are choosing Rocky DEM to evaluate their bulk materials handling systems because Rocky DEM simulations are so realistic.


MINING: MILLS AND CRUSHERS

Stirred Mills, SAG mills, Crushers, and High Pressure Grinding Rolls (HPGR) are becoming increasingly used for fine and ultra-fine grinding. This technology is still not well understood when used in the context of mineral processing, making process optimization problematic. Rocky 3D DEM simulations of grinding media flow can help engineers evaluate the relative performance of these kinds of equipment. Media flow patterns, energy absorption rates, particle breakage, energy spectra analysis, and size distributions are some of the many criteria that could be analyzed using Rocky DEM. Additionally, coherent flow structures, equipment wear, mixing efficiency, and transport efficiency are all able to be evaluated by using this tool.

MINING: TRANSFER CHUTES

Rocky DEM software is a revolutionary way to simulate how material flows through various transfer chute environments. Using 3D CAD models of the various chute components, Rocky DEM calculates how each individually customized particle interacts with each material and boundary surface, providing a realistic simulation of how the transfer point is likely to function. This powerful ability makes the often expensive step of testing and fabrication of transfer points a thing of the past. Rocky can also help engineers increase production and optimize the overall life of components by helping to reduce spillage, chute plugging, belt and liner wear, dust, and noise.


PROCESS EQUIPMENTS: SCREENING AND SORTING

Large scale industrial screens are used to separate particles by size into multiple product streams. Their performance in terms of throughput and screening efficiency is of vital economic and industrial importance and in many applications, can be a limiting factor in the overall efficiency. Rocky's Discrete Element Method (DEM) predictions of flow and separation efficiency can help engineers evaluate screening performance, mass flow distribution, force distribution, and surface wear. Coupling this information with an external FEA Solver (ANSYS), Rocky DEM can also identify resonance and operational problems within the equipment.


PROCESS EQUIPMENTS: MIXING EQUIPMENT

A great challenge in various industry operations is understanding particle behavior inside a closed system such as mixers. Rocky DEM simulates with precision and accuracy how material behaves inside this kind of equipment. Also, it provides a unique tool for engineers and designers to reduce the negative impact of variability in the bulk flow characteristics of feedstock, which can help increase productivity. By analyzing the particle velocity inside these closed systems, it is possible to maintain product integrity and quality, and reduce waste. For these reasons, Rocky DEM is the best solution to simulate mixing equipment and can be used in many different types of applications thorough the pharmaceutical and agricultural industries.


PROCESS EQUIPMENTS: FEEDERS

Any type of screw feeder equipment can be simulated using Rocky DEM, which helps engineers and designers to develop solutions in a more productive and efficient way.
