The consumption of grinding aid when grinding OPC in a vertical roller mill is typically in the range from100 to 300 g per tonne of cement. The ball mill system thus has an advan- tage compared to the vertical roller mill with respect to the use of a grinding aid for grinding of OPC.

A more appropriate term is vertical roller mill or VRM for short. There are two different types of vertical mills: Vertical roller mills. Such mills normally have integrated classifier. This means plant design is more compact / simple in comparison to ball mill / classifier circuit. On the other hand fineness is limited. Agitated vertical mills. They have much higher specific grinding energy and from there are for

The following presents a comparison of the two mill systems with reference to these issues. Grinding process The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture ...

applications of the vertical roller mill for cement grinding are less prevalent. The two-compartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding installations although the vertical roller mill now has emerged as a viable alternative to the ball mill system and has increased its share of the market for cement mills over the

Vertical roller mills Vs ball mills has long been a raging debate in the cement industry. In spite of the fact that vertical roller mills have been around for over ten years now and have gradually become the standard as far as cement manufacturing goes, several cement manufacturers still prefer ball mills for cement production when they want to design new grinding plants or a new integrated ...

The comparison of vertical roller mill and ball mill in Traditionally, the closed circuit ball mill equipped with high efficiency separator has been the most widely used system for cement grinding.

15/02/2012 Compared to a ball mill, a vertical roller mill is a very versatile mill suitable for, and easily adaptable to a wide range of products. However, a ball mill can be subject to an upgrading to a higher capacity, which is not an option for a vertical roller mill.Although cost of erection and cost for civil works show large regional variations the total cost of installation is in most cases somewhat higher for a

Ball mil and vertical roller mill were used as the comminution characteristics for grinding of chromite first-order breakage kinetics in the case of ball mil and vertical roller mill in different ...

Overall, the investment of the roller press grinding system is slightly lower than that of the vertical mill grinding system, but the difference is less than 5%. Comparison. When grinding raw meal, the unit power consumption of the vertical roller mill and the roller press is about the same, which is 7-8kWh/t. But the vertical mill is usually slightly higher.

05/05/2020 The comparison between a vertical mill and a tube mill is a little bit more complex and must not consider only the speciffic power consumption. For energy savings sometimes is quite necessary to analyse the complete grinding department. Of course a vertical mill have a reduce energy consumption for grinding, but the mill fan require a very big motor (the pressure drop in the vertical mill ...

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.What is the difference between a vertical roller mill and .A vertical roller mill is an energy efficient grinder that grinds items into incredibly fine powders used for ceramics, cements, pyrotechnics, etc. using vertical

10/03/2015 Comparison of vertical roller mills with tumbling mills on the lab and pilot scale • Lab scale tumbling mills arranged in the (energy) optimized comminution sequence • Energy control by torque measurement, dispersity control by permeametry • Based on energy expense for grinding only the tested vertical mills are more efficient.
