ball mill and vertical mill are the most often used types of cement mill. Although ball mill can be utilized intended for grinding of assorted varieties of materials and will work in lots of various circumstances, the efficiency of ball mills is comparatively lower and so they need to have much more electrical power consumption. Compared with ball mills, vertical roller mill progressively seize the market for their excellent performances, lower electricity intake and simple operation.

Vertical mill intended for cement is composed by cement separator, grinding roller along with the grinder. Separator could be the vital part which decides the fineness diploma from the cement. By adjusting the cement separator, we are able to get a variety of fineness degree of cement according to functional requirements. High efficiency separator enables the vertical mill to own the following positive aspects in comparison with ball mill.

1. High Grinding Efficiency

Vertical mills grind the materials together with the principle of grinding by layers. The power consumption of vertical mills is 20%-30% reduced than that of ball mills. Aside from, with all the enhance of moisture element within the resources, the energy-economizing influence is getting much better.

2. Straightforward Technological Method

Equipped with high efficiency separator, the vertical mills feed and transmit the resources by scorching flue gas. Powder classifier and hoist will not be essential. For that reason, the technological process of vertical mills is comparatively simple. The failure rate with the machine is very low and operation price is high. The development area of vertical mill is 70% that of ball mill and the development space is only 50%-60% that of ball mill. Huge volume of money can be saved in building expense.

three. Powerful Dry Capability

By implementing hot flue gas in substance transmission, vertical mill can management the temperature in the intake air when it's grinding massive materials. Vertical mill can dry resources with 12-15% moisture element, but ball mill are only able to dry resources with 3-4% moisture component.

4. Even Grain Composition

The supplies only keep within the vertical mill with regard to two to a few minutes, even though they stay 15-20 minutes within the ball mill. During this way, the chemical parts and fineness with the resources could be tested and adjusted rapidly. So cement produced by vertical mills is of even grain composition and fineness.

5. Much less Weariness & High Efficiency

In the operation of vertical mills, there is no direct contact between the resources along with the metals, so there is significantly less weariness intended for 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 rewards 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.
