maximum size of material for vertical mill grinding

Clinkersizeand cementgrinding. ... For mostmillsystems, manufacturers recommend the following rawmaterial size: Fine clinker is more of an issue inverticalrollermills, since it can quickly slip under the rollers, leading to vibration and instability. As a general rule, there should be less than 25% of clinker that is below 1mm insize

horizontal vs vertical mill custom milling consulting

horizontal vs vertical mill custom milling consulting

Sep 08, 2013· Traditional vertical mills and ball mills are often limited to a finished particle size of approximately5 microns,which can be achieved only with careful attention to media size. Horizontal Mills. In contrast to vertical mills, horizontal mills have certain characteristics that are better suited to wet grinding. A horizontal mill is generally made up of a horizontal tubular grinding chamber, in the center …

Jul 01, 2003· Figure 3 depicts the effects of mediasizeongrindingtimes. From this plot, it is shown that a target fineness of 80% < 2 microns is normally achieved in 315 minutes of recirculationmillingwith 1.0 to 1.4 mmgrindingmedia. By reducing the media diameter to 0.6 to 0.8 mm after 90 minutes, the target grind is achieved in only 150 minutes
