Vertical roller mills (VRMs) are the main alternative means of grinding the clinker and are increasingly being used. For a quick introduction to VRMs see, for example, this advertisement on Youtube for an FL VRM. As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum (CaSO 2 O).
The grinding media balls in the ball mill are used in cement plant to help grind blocky or granular grindable materials produced in the cement manufacturing process, so as to achieve the effect of grinding. Vertical roller mill(VRM) and clinker grinding mill and other cement grinding mill are also very common in cement plant.

Vertical roller mill optimisation News Events Training. Vertical roller mills (VRMs) have become the equipment of choice for raw and solid fuel grinding in cement factori Increasingly modern cement plants also use VRMs for cement grinding However opportunities for the optimisation of VRMs are less obvious than with ball mills as all processes of grinding drying classifiion and regrinding
· Abstract: For several decades the cement industry has successfully utilized vertical roller mills (VRM) for grinding of raw materials and solid fuels. Most recently, this technology has been employed for the combination of Portland cement, blended cements and slag cements. The VRM offers several benefits compared to the ball mill in regards to operating costs and flexibility.

CEMTEC's completely new and innovative vertical roller mill constitutes one more step toward more efficient grinding of soft and mediumhard products.
Progress with Grinding Aids for Vertical Roller Mills. The effect of grinding aids on the comminution of cement is based on the dispersion of fine particles. It is a misunderstanding that grinding aids for vertical roller mills (VRMs) should stabilise the material bed between the rollers and the table by adhesive forces between the particles.
