Vertical raw mill is important equipment widely used in the cement raw meal cement raw materials grinding section of the cement production process in cement plant. Because the vertical raw mill is the use of roller grinding principle to crush materials its vertical raw mill operation is more efficient and energy-saving product output is more stable so in cement industry electric power metallurgy
Vertical mill is a equipment that grinds materials by relative rolling of a grinding roller on grinding disc. There are several aspects to the normal operation of the vertical mill The material layer of Vertical mill The proper thickness of the layer and stable layer are basis for stable operation.

Dec 11 2020 Vertical raw mill is one kind of raw mill generally used to grind bulk granular and powder raw materials into required cement raw meal in the cement manufacturing plant. Vertical raw mill is an ideal grinding mill that crushing drying grinding grading transfer set in one. It can be widely used in cement electric power metallurgy chemical industry non-metallic ore and other industries.
Cement raw material has been almost exclusively ground in roller mills vertical air-swept grinding mills since the sec-ond half of the 20th century. Loesche was and is the pio-neer of this technology. Hundreds of Loesche mills have been used in the cement industry across the world to the present day. They operate with two three four and six roll -
