Vibratory grinding mills have been around for some time, but the VKE mill is a unique and major development in vibratory fine grinding, utilizing a tuned spring system to completely suspend the grinding chamber and the vibratory motor energy source.This design saves and reuses the "rebound" energy and permits the construction of a low-cost and maintenance-free mill.
Pulverizer - Wikipedia
The grinding force for coal pulverization is applied by a loading frame. This frame is connected by vertical tension rods to three hydraulic cylinders secured to the mill foundation. All forces used in the pulverizing process are transmitted to the foundation via the gear reducer and loading elements.
