Grinding of raw materials the grinding efficiency of the vertical roller mill combined with an ability to dry grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system however despite these benefits applications of the vertical roller mill
Due to the varying classification settings of the mills von rittingers theory of comminution was used to compare the relationship between specific effective energy consumption and particle size reduction of the planetary ball mill knife mill and ringroller mill the bwi energy consumption was not compared as the energy was estimated using
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
The vertical roller mill has high energy efficiency and the installation space is smaller compared with tube mills these days the vertical roller mills have been widely adopted astructure 1 the rollers are hydraulically pressed against a disc table and the feed is
Earlier work by fuerstenau and kapur on the comminution of quartz in a singleparticle roll mill and in a dry ball mill showed the energy efficiency of ball mill comminution to be 22 thus as a mechanical device for producing fine particles the ball mill is reasonably efficient energetically
Grinding of raw materials the grinding efficiency of the vertical roller mill combined with an ability to dry grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system however despite these benefits applications of the vertical roller mill
The energy consumption rate of the ball mill is relatively low at present there is a tendency to be replaced by vertical mills roller presses etc but the ball mill has a granular shape that is approximately spherical which is conducive to raw material calcination and cement hydration hardening
Ball mill with roller press in semifinishing mode fines saving often minimal or even negative feed o combined grinding allows better mill optimization including use of monochamber mill o capacity may almost be doubled and energy reduced by 10 20 o however due to lower reliability and operational sensitivity actual energy
Working principle operation the apparent difference in capacities between grinding mills listed as being the same size is due to the fact that there is no uniform method of designating the size of a mill for example a 5 x 5 ball mill has a working diameter of 5 inside the liners and has 20 per cent more capacity than all other ball mills designated as 5 x 5 where the
Roller millhch it can produce ultrafine powder low energy consumption low investment cost large scale ring roller mill has good market prospect disadvantage low output mill classifying high energy consumption it is almost obsolete in nonmetallic mineral industry
The following four ball mill is very common the main difference between them lies in the structure of different grinding parts and according to the shape of the structure naming lthe disc and roller mill referred to as flat plate plate grinding mill components is circular flat disk and roll formed
In addition the vertical mill uses a grinding roller to directly crush the ground material on the grinding disc and saves energy by 30 to 40 compared with the ball mill system in general the power consumption of the vertical mill can be reduced by 30 to 50 compared to the energy consumption of the ball mill in the case of the same
Power consumption per pound generally higher than roller mill but highly efficient on circuflow model hammer mill due to 300 degree screen and large rotor diameter resulting in high tip speed perforated screens or grates are used to regulate particle size post grinding ie positioning of the mill after the grain blending process is possible
Ball mill loading wet milling paul o abbe ball mill loading wet milling when charging a ball mill ceramic lined mill pebble mill jar mill or laboratory jar use on a jar rolling mill
May 05 2020 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 system is 9001100 mm wg there are many differences between vertical roller mill and ball millnot only in production equipment to choose depends on your actual
The ball mill is key equipment in grinding industry it is widely used for the cement coal sand fertilizer glass ceramics etc but its final product cost is high as ball mill bm grinding is lowest 5 when compared with vertical roller mil
