VRM is a vertical roller mill used for grinding raw materials into cement while a ball mill is used for grinding raw materials into fine powder.

• VRM uses pressure and shear generated between the rollers and the rotating table to crush and grind raw materials.

• Ball mill uses impact and attrition between grinding balls and ore particles to crush and grind materials.

• VRM is more energy-efficient and has a higher grinding capacity compared to a ball mill.

• Ball mill is more suitable f...read more

Blaine is a measure of fineness of cement particles, while residue is the material left on a sieve after cement is passed through it.

• Blaine is a measure of the surface area of cement particles, indicating their fineness.

• Residue is the material left on a sieve after cement is passed through it, indicating the amount of coarse particles in the cement.

• Blaine value is typically expressed in cm²/g, with higher values indicating finer particles.

• Residue is usually expressed as a per...read more
