Multiphase flow simulation of a simplified coal

2005-7-25  Coal pulveriser is a device used for separating large and small particles by relying, in general, on centrifugal forces to cause different size particles to follow different trajectories. By means of bowl rotation and due to centrifugal forces, the coal particles are moved away to clearance, where the pressure-rollers crush them to fine powder.
