It can be widely used in cement, electric power, metallurgy, chemical industry, non-metallic ore, and other industries.
Sep 20, 2018 Generally speaking, ball mill is the most common powder grinding machine in the cement industry. However, with the development of the social technology, vertical roller mill can replace ball mill, in some specific circumstances especially when we want to process the powder below 1250 mesh, the vertical roller mill has absolute advantages.The highest wear occurs on the wear parts of the grinding elements as is the case with any type of vertical mill. Therefore, ease of replacement and regeneration is a major feature of the mill. MVR 6000 C-6 cement mill with MultiDrive , Siam City Chip Mong Touk Meas, Cambodia.

Today, however, the OK mill has become an excellent example of a mill design that has overcome the difficult grinding conditions associated with finish grinding of cement clinker and related products.
Jan 06, 2021 A two-compartment ball mill with a highly efficient separator is still procured for new cement grinding units installation, although the vertical roller mill has now become a true competitor and alternative for ball mill and has increased its market share in the cement mills in recent times.Recently, especially from 1980s, grinding system using the vertical roller mill, which has effective grinding performance, is developed and applied in the cement grinding process. Descriptions . Basic equipment structure of the vertical roller mill for cement grinding is the same as the vertical roller mill of raw material and coal grindings.Taking grinding P o42.5 cement as an example, the pre grinding closed-loop system composed of roller press or external circulation vertical mill and powder concentrator has a circulation load rate of 200 – 300 , and the specific surface area of the selected materials is 180-280m 2 kg. The following table lists the main machine preparation and the product particle size of several cement grinding systems.
Vertical roller mill application Control challenges Among the operational challenges of a vertical roller mill are the fast dynamics of the process. Compared to ball mills with dynamics changing in 15-20 minutes, vertical roller mills have dynamics changing in 2-4 minutes. The fast dynamics necessitate even closer attention to , LOI.幻灯片17 4.Grinding system Ball mill is the earliest grinding equipment used in cement production industry, and it still plays a leading role. Although its efficiency is very low, for example, the power consumption of single particle is only 6 - 9 , the maintenance of ball mill is simple and reliable, especially for cement clinker grinding.One cement factory in China purchased GRMK53.41 cement vertical mill from CHAENG in 2012.
