ball mill and vertical mill are the most frequently employed kinds of cement mill. Though ball mill may be used intended for grinding of varied sorts of supplies and can function in lots of different scenarios, the efficiency of ball mills is comparatively low plus they need a lot more energy use. Compared with ball mills, vertical roller mill steadily seize the marketplace with regard to their excellent performances, lower electrical power intake and straightforward operation.
Vertical mill intended for cement consists by cement separator, grinding roller along with the grinder. Separator will be the crucial component which decides the fineness degree in the cement. By adjusting the cement separator, we could get a variety of fineness degree of cement according to practical needs. High efficiency separator enables the vertical mill to personal the next rewards in comparison with ball mill.
1. High Grinding Efficiency Vertical mills grind the supplies together with the principle of grinding by layers. The ability intake of vertical mills is 20%-30% reduced than that of ball mills. Aside from, using the improve of moisture element in the resources, the energy-economizing influence is acquiring far better.
2. Easy Technological Method Equipped with high efficiency separator, the vertical mills feed and transmit the resources by hot flue gasoline. Powder classifier and hoist will not be needed. Consequently, the technological method of vertical mills is comparatively basic. The failure charge of the machine is lower and operation price is high. The construction place of vertical mill is 70% that of ball mill as well as the construction house is just 50%-60% that of ball mill. Massive quantity of money could be saved in construction expense.
three. Robust Dry Ability By implementing very hot flue fuel in material transmission, vertical mill can control the temperature of the consumption air when it truly is grinding big supplies. Vertical mill can dry components with 12-15% moisture component, but ball mill can only dry resources with 3-4% moisture part.
4. Even Grain Composition The components only remain while in the vertical mill regarding two to 3 minutes, although they remain 15-20 minutes in the ball mill. During this way, the chemical elements and fineness of the supplies might be examined and modified rapidly. So cement made by vertical mills is of even grain composition and fineness.
5. A lot less Weariness & High Efficiency Inside the operation of vertical mills, there is no direct contact between the materials as well as the metals, so there is a lot less weariness regarding grinding body. The weariness per unit is generally 5-10g/t. The weariness per unit of ball mill is as high as 500g/t.
Besides all the advantages mentioned above, vertical mills are also of less noise and dust because of its full sealing system. No wonder why vertical mill has become the new favorite in cement grinding.
