Here we analyse the effect of grinding nozzles pressure on the particle dynamics and fluid flow by numerical simulation. The average velocity gradient in the radial direction is very steep for low mass loadings, indicative of rapid shearing, but it decreases significantly as the particle mass loading is increased. The dissipated collisional ...

The grinding gas nozzles induce an internal vortex and cause interparticle collisions. Once the material has been sufficiently reduced in size, the drag force of the grinding fluid overcomes the centrifugal force acting on the particles and entrains them out of the mill through a …

Coherent-jet nozzles give better grinding performance because they concentrate the coolant into the grinding zone, allowing the pores of the wheel to be fully filled, and thereby minimize the applied flow rate. A dispersed jet pumps air and coolant into the grinding wheel, displacing some of the fluid with air.

These nozzles provide a coherent jet of high velocity grinding fluid that penetrate into the pores of the grinding wheel. This allows the coolant to get pulled by the wheel into the grinding gap, providing lubrication and cooling right where it is needed. The result is a reduction in thermal damage and longer wheel life.
