Dynamis relies on Rocky DEM to improve performance of rotary calcination furnace

The brazilian engineering company specializing in the thermal field used particle simulation to increase productivity using Dynamis’ current equipment.

The R&D Team turned to Rocky DEM to accurately simulate the operating conditions of the calcination furnace and analyze how different stirring techniques impact mixing efficiency. Dynamis uses Rocky DEM to simulate the dynamics and heat transfer for each solid particle within the operating conditions of the rotary furnace and analyze how material processing for different rotary cylinder geometries impacts homogeneity.

Particle simulation was the only way to prove that we could increase productivity using Dynamis’ current equipment. Analytical models are not available for these types of analyses and using physical prototypes would lead to inaccurate results because wewould never be able to completely reproduce operating conditions. From the simulation results it is possible to prove that the proposed change brings significant gains for the uniformity of mixing and temperature, and consequent improvement in the efficiency of the equipment.”

Increasing the efficiency of a calcination furnace by analyzing how three different rotating cylinder geometries affect particle distribution and temperature during mixing.

Using Rocky DEM software to simulate the operating conditions of the rotary furnace and to analyze how material processing for different rotary cylinder geometries impacts homogeneity.

Rocky DEM particle simulations enabled Dynamis to visually compare the mixing results within three different cylinder geometries and analyze particle distribution by size. Based on the results, Dynamis was able to select the mixing design that produced the least amount of segregation and the highest performance.
