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.

When it is required to repair a vertical crack in the concrete that runs in straight lines, this is a good method for its cost-effectiveness and less time-consuming. In this method, holes are drilled vertically in the cracks and a key is formed by passing down a grout. The grout key drilled in concrete helps in preventing leakages.

In comparison, V-100 epoxy grout is stronger than V-1 cement grout in less than 8 hours and final machine alignment can usually be done in 24 hours. Working Time – V-1 cement grout allows 30-45 minutes in which to finish pouring while V-100 epoxy allows 10 – 15 minutes. Most V-100 3-Part epoxy grouts used for deep pours allow 45 – 60 minutes.
