I see that several have answered based on dry grinding, i.e. Vertical Roller Mill vs. conventional Ball Mill. If we instead focus on wet grinding, we should differentiate between stirred media grinding, which can be both vertical and horizontal, and tumbling mills with manufactured grinding bodies. A continuous grate-discharge tumbling mill ...
Ball mill machine has always been the main grinding equipment in wet cement production. In the early years, the rod mill was first used in cement raw meal grinding, which increased the output of the grinding section by 31%, saved energy by 27%, and reduced the consumption of grinding media by 47%.
Efficiency of ball mills vs. roller mills I would like to know if anybody knows the power consuption in KW per ton of a ball mill milling cement clinker at a feed of 1" minus in order to produce Portland Cement. I would also like to get the same info for a roller mill. 7th April 2008, 10:12 #2. D.Lucut.
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 of the individual particles in the bed, although the ...

I am researching the differences between making or shall I say refining chcolate and ingredient mixes on a ball mill refiner versus roller refiner process. There seems to be a difference of opinion.
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 ...
0. The difference between a roller mill and a hammer mill is: A hammer mill uses rotating hammers to pound grain through a screen and it requires a lot of horsepower. You get a lot of powder with larger deviation from the hammering. A roller mill uses cylindrical rollers that grind the grain when it goes through them, which requires less ...
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 ...
Comparison Between Cement Grinding Roller Press Vs Ball . Difference between vertical grinding mill and bowl mill. difference between raw mill and ball mill . cement grinding vertical roller mills versus ball mills. cement industry the ball mill was really an epochmaking breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal and still today
Vertical roller mill adopts three-dimensional structure,which needs less space,ball mill is just the opposite.And vertical roller mill is cheaper than ball mill,if you don't need high productivity,roller mill is a better choice. I think this note,which called what is the difference between vertical roller mill and ball mill can help you.

Ballmill versus vrm ball mill and vrm comparisonpopulareducationcoza. vertimill vs ball millgrinding911metallurgist forums support a more appropriate term is vertical roller mill or vrm for short this means plant design is more compact simple in comparison to ball mill classifier circuit difference between vrm and ball.
Roller mills simply "roll" or "crush" product between two revolving cylinders. This latter process has the distinct advantage of requiring considerably less power, although it is not possible to achieve the fineness of final grind through a roller mill that can be achieved through a hammermill. In a hammermill, the screen-hole diameter ...
The difference between vertical roller mill and ball mill The ball mill is generally composed of a horizontal cylinder, a hollow shaft for feeding and discharging, and a grinding head. The cylinder body is provided with an abrasive body, the cylinder body is made of steel plate, and the steel lining plate is fixed with the cylinder body, and the grinding body is generally a steel ball, and ...
