typical reduction ratio for ball mill vrm

Vertical Roller Mill The vertical roller mill (VRM) shown in Figure 4 is an air swept, medium-speed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulically-loaded grinding pressure through three grin- ding rollers onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal

    If a ball mill uses water during grinding, it is a ‘wet’ mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders.

    Crusher Reduction Ratio Mineral Processing amp Metallurgy

    Jan 12, 2016 Crusher Reduction Ratio. I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged.

    Predicting the grinding energy of vrm depending on

    VRMs (vertical roller mill) and HPGRs (high pressure grinding rolls) are compression milling technologies of which the grinding efficiency of them was found to be higher than that of the conventional circuits, i.e. ball milling (Aydoğan and Benzer, 2011). Within these types of grinding machines, a bed of material is compressed between the ...

    There are two types of mills which are mostly used in cement plants for grinding raw mix viz. Ball mills and VRM. Ball mills Ball mills are essentially fine grinding units capable of grinding material to a fineness say 84% passing 90 microns. The size reduction technique involved here is attrition and impact.
