However, despite a generally good performance of vertical roller mills used for grinding of cement and related products the vertical roller mill is still inferior to the ball mill in terms of sensitivity to variations of mill feed quality (fineness) and mill feed rate. Product quality
Cement Grinding Vertical Roller Mill Versus Ball Mill. We discuss the types of ball mill, the basic principles of the ball mill, how it works, the details of design including equations for optimum dimensions in all cases, some manufacturers for the ball mill, and estimation of the cost the ball millntroduction ball mill is an efficient tool for grinding many materials into fine powder.
The consumption of grinding aid when grinding OPC in a vertical roller mill is typically in the range from 100 g to 300 g per ton of cement. With respect to the use of grinding aid for grinding of OPC, the ball mill system thus has an advantage compared to the vertical roller mill.
For grinding cement, two types of mills are used - ball and roller. Recent decades have proven the great effectiveness of a vertical roller mill for grinding raw materials.
Cement Grinding Vertical Roller Mills Versus Ball Mill. cement raw material introduction. Cement in powder form can be changed from plasticity paste to hard stone-like body and can become a total cemented granular materials through physical and chemical processes after being mixed with water. So cement is a good mineral binder.

Ball mills are factory made and transported to the plant site of the buyer while VRM is built on the site of the cement plant. This helps to reduce cost and complicated logistics issues. The equipment cost is, however, higher for a VRM than a ball mill.
201973Vertical roller mill vertical grinding mill is mainly suitable for ultrafine powder processing of noninflammable and nonexplosive brittle materials with medium and low hardness and Mohs hardness of 6. The ball mill is the key equipment for grinding the material after it has been crushed. The ball mill has low energy utiliation efficiency.
1.. IntroductionConventionally multi-compartment ball mills are used in finish grinding of cement. However, they are relatively inefficient at size reduction and have high energy consumption, so it is increasingly common to find grinding technologies such as High Pressure Grinding Rolls (HPGR), vertical mills and Horomill ® in cement plants.

I think this note,which called what is the difference between vertical roller mill and ball mill can help you.
The sequence to evaluate the vertical roller mills consisted of a laboratory jaw crusher, a rod mill and two ball mill stages with differing grinding media. The dimensions and settings of the laboratory mills are given in Table 1 and are illustrated in details in ( Boehm and Flachberger, 2006 ).
cement grinding vertical roller mills versus ball mills. Cement grinding Vertical roller mills versus ball mills grinding of materials The grinding efficiency of the roller combined with an ability to dry grind and classify within a single unit gives the roller a decided advantage over a system However despite these benefits applications of the roller for cement grinding are less …
1. Roller Press Cement Pre Grinding System. The most noticeable feature of the roller press cement pre grinding system is that the fine material power ground at the middle part of the roller will be sent to the ball mill for further grinding. The cement grinding process in this system is rather simple with less equipment required.
Cement Grinding Vertical Roller Mills Versus Ball . the most significant advantage of a vertical roller mill compared to a ball mill system is related to the consumption of electrical energy of the two systems. it appears from the table that the specific energy consumption of the ok mill system is 25 - 40 lower than for the ball mill system.
