Vertical roller mill is a newly-designed grinding machine that is primarily used for the powder processing of mineral products in industries such as metallurgy, building materials, chemical, mining and so on. It is suitable for processing various non-flammable and non-explosive mineral materials with Mohs hardness below 9.3 and humidity below 6%. Vertical Grinding Mill Performance and Features 1.Unique pressure device design of star rack, the production increases by 30%-80%. 2.Higher grinding force, finer grain size, wider range of applications. 3.Overlapping multistage sealing, good dedusting effect. 4.Easy-to-adjust classifier, wear-resistant parts, long replacement cycle of internal roller and ring.
