DEM (discrete element method) is a numerical technique that models the interaction between individual particles and boundaries to predict bulk solids behavior. This tool can easily model moving boundaries and is used to gain better understanding of particle flow dynamics. The knowledge is then applied to design more efficient equipment, thus improving process efficiency and product quality.
DEM is used to predict:
- Bulk material flow patterns
- Bulk material flow rates
- Force, torque, and power consumption of equipment
- Impact forces on particles and boundary surface
- Wear patterns on boundary surface
- Velocity profiles and dead zones
- Particle distribution in segregation and blending
Your process is modeled by our engineers with our in-house developed proprietary code that has been extensively used to solve many handling problems around the world in industries including mining, chemical, agriculture, food processing, pharmaceutical, and power. These project examples below are proof that our DEM capabilities are a dependable tool to quickly develop the right solutions for your material handling process.
Jenike & Johanson has a passion for particles. We know that though spheres are computationally attractive, they in many cases will not provide accurate or representative DEM modeling respects. Look at the simulation below, illustrating the behavior of a sphere vs. clustered spheres vs. polyhedral particles. Clearly the spheres and clusters do not mimic the true flow behavior of the shaped particles.
