Optimizing cement grinding with chemical additives

For example, as cement grinding progresses and grains become smaller, the attractive thermodynamic, physical, mechanical and chemical forces result in strong adhesion of particles. This causes agglomeration (or clumping) of cement particles. This limits the increase in specific surface area, and can result in coating of the mill internals ...

Grinding (abrasive cutting) - Wikipedia

Types of centerless grinding include through-feed grinding, in-feed/plunge grinding, and internal centerless grinding. Electrochemical grinding is a type of grinding in which a positively charged workpiece in a conductive fluid is eroded by a negatively charged grinding wheel. The pieces from the workpiece are dissolved into the conductive fluid.
