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.

The cement plant's vertical roller mills (CKP) are used to crush cement clinkers and prepare for the next step, which are ball mills. The grinding mechanism of the CKP imposes pressure on the particles instead of impact forces. It has higher energy efficiency than do the ball mills. Although more actual operational data are required to set up ...

Our Roller Mill Equipment. Automatic's industrial grain roller mills produce precise particle size every time, even when it comes to high volume grain processing – as much as 15,000 bushels an hour for our hardest-working, high-capacity models. Parallel, corrugated rolls uniformly process corn and other grains to exactly the right size.

Grinding table is one of key parts of vertical roller mill. It includes drag rings, lining plate and base. The optimization and improvement are made basing on traditional grinding table casting technology, that the most advanced sodium silicate-bonded sand molding technology, to overcome deficiencies in structure and make the grinding base bear force equivalently.
