Bulk Material & Particle Flow Analysis
Reliable bulk material flow is essential for maintaining stable throughput across material handling and storage systems. Variations in particle size, moisture, material properties, equipment geometry, and operating conditions can result in segregation, material build-up, uneven discharge, excessive impact, spillage, and flow restrictions.
MACPROTEC applies advanced particle-flow simulation, including CFD-DEM and DEM-based analysis where appropriate, to evaluate the movement and interaction of bulk solids throughout handling systems. Our studies provide detailed insight into particle trajectories, material distribution, impact behavior, and flow patterns, helping optimize equipment geometry, improve material transfer, and reduce operational problems.
