In the cement industry, the necessity of continuous improvements in the grinding process and the related cost reduction has promoted the proliferation of vertical cement mills worldwide.
ادامه مطلبProgress 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.
ادامه مطلبtest the effect of the grinding aid. In contrast to tests with ball mills, the effect of grinding aids in a VRM is already visible and audible after 10-20min. Before the addition of the grinding aid, a blank test was run to confirm reproducibility (See Figure 2). Starting from this baseline, the new grinding aids were added onto the transport ...
