Little abrasion wear, Long service life

Based on 30 years of development experience of grinding equipment, LM Heavy Industry produced LUM Series Superfine Vertical Roller Grinding Mill to make ultra-fine powder. The grinding roller doesn't contact with millstone usually, which makes abrasion little and service life longer.

Applications: Superfine dry powder of none-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on.

Calculating Mill Drive RPMs: Is Your Mill Up to Speed?

In order to know for sure all sections are matched and properly balanced, one must also calculate the speed for these smaller sections to the larger sections. The bottom throat diameter of each bottom driven roll, in each section, breakdown, fin and sizing, is the not only the drive point for these sections, but they also give reference to the "bottom" or "metal" line of the entire mill.

A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING

Rolls are tools used in rolling mills to reduce the cross section of metal stock. The weight of rolls may vary from a few kilograms up to 250 tonnes. Under rolling conditions the contact area between roll and stock suffers wear, the other parts of a roll body and necks have to be considered as normal parts of designed components under high load. This means that necks should not experience
