How the mill achieves uniform particle size To achieve a uniform final particle size with minimal fines, the roller mill must have the right roll surface, roll speed ratio, and roll gap for your application. Roll surface. Typically, the roll surface is corrugated rather than smooth to achieve efficient size reduction, as shown in Figure 3.

of the particle size. Thanks to the integrated separator (classifier) the grounded material is separated after each passage. In comparison to a ball mill (with external separator), the separation is sharper. Therefore the particle size distribution (PSD) of the cement has the tendency to be narrow ( high n'' according RRSB). This
Feb 01, 2000· Further, it is difficult to control the particle size distribution freely. In the case of cement products, since the particle size distribution is important from the standpoint of product quality, there exists a need of widening the particle size distribution of the cement products obtained by the prior art vertical roller mill 1.
However, particle size distribution is again a problem, and roll presses are now increasingly popular as a "pregrind" process, with the cement finished in a single chamber ball mill. This gives good cement performance, and reduces energy consumption by 2040% compared with a standard ball mill system.

Vertical Roller Mill Play An Important Role In Cement Industry. Vertical roller mills create a particle size distribution with a sharper cut in comparison to cement milled in a traditional ball mill. That is, the particle size distribution is in a narrower band.
Vertical Roller Mill In Cement Raw Mix EPrintsUSM. Raw mix grinding process in the vertical roller mill could be described by the figure l particle size distribution of the raw mix experimental and calculated. Read More; Math Cement Module1 SlideShare
portion of very fine particles and a broad particle distribution. Expressed as inclination of the particle size distribution according RRSB, cements from ball mills generally have a rather low slope [n'']. In a VRM the grinding takes place by pressure and shear force. The clinker passes within seconds between roller .
In processes such as cement milling, where the particle size has to be reduced about a thousandfold, the productsized particles produced in the early part of the process impede the grinding of the rest, and will tend to end up finer than they need to be.

A comaparative study on the effect of using conventional and high . crushing on the grinding kinetics of downstream ball milling of an iron ore.
Feb 10, 2016· VRM has less flexibility in controlling particle size distribution. Overall ball miil is good option for Cement mill but only has limitations for higher capacity, as two ball mill to be installed for One VRM, but in case of breakdown one ball mill can be in operation. Trust this clear your clarifications on equipment selection for cment production.
particle size distribution curve. By these measures it has been possible to obtain particle size distributions for cement ground in OK mills similar to those for cement ground in ball mills (BM), as shown in Figure 6. Figure 6: B It should be noted, however, that operation to achieve a wide particle size distribution (low nvalue) has a cost.
