    Vertical Roller Mill (600 45μm) Grinding Mill

    Vertical mills Flexible mills with integrated separator. The vertical mill enables high energy economy, and convinces with low specific wear values. Drying of the feed material, grinding, separating, and material transport take place inside the mill. It is thus especially well suited for grinding products with high proportions of wet components.If rods become misaligned, grinding action is lost and, importantly, rod tangles occur. Maximum rod length is limited to about 6.1 m (20 ft). This in turn limits the length, diameter, and capacity of rod mills. The heavier rods acting upon the lifters and liners result in greater wear on the mill liners.

    7.0 N mm 2 in order to limit the stress on the rollers (grinding pressure = grinding force roll diameter roll width). The pressure between the rolls can be lower for grinding granulated slag, raw material or for special applications, such as preparation of ore. To keep wear costs to a minimum when grinding ore, the rollers are studded.The early mills were built with maximum capacity of 6 tons per hour. By 1930 the maximum capability of this mill design had been increased to 15 and then to 25 tons per hour. Grinding mills use one , two or all three of the basic principles of particle size reduction namely impact, attrition and crushing.
