Cement vertical mill, also called roller mill, is another raw mill commonly used in cement plants. Compared with the cement ball mill, it has a great difference in structure, …

When grinding raw meal, the unit power consumption of the vertical roller mill and the roller press is about the same, which is 7-8kWh/t. But the vertical mill is usually slightly higher. The system of the vertical grinding mill is simple and stable. It has ideal adaptability to material moisture and can achieve the goal of energy saving on the ...

Raw mill is also called cement raw mill, similar to cement ball mill, it is an important cement milling equipment used in the cement production process. Raw mill is mainly used for grinding cement raw meal in the cement factory production process. It is also suitable for metallurgical, chemical, electric power and other industrial mining enterprises to grind …

A: Cement mill is generally more energy-efficient than raw mill because the clinker particles in the cement mill are already in a fine powder form, and less grinding is required. The main difference between raw mill and cement mill lies in the raw materials and equipment used to grind them into a fine powder. Understanding these differences is ...

Over the last three decades the vertical roller mill has become the preferred ball mill for 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 …

For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, i.e. whether hardfacing is applied.

Both cement ball mills and vertical cement mills can be used to grind slag. However, vertical cement mills are generally more suitable for grinding and drying slag materials, as they have a higher drying capacity compared to ball mills. Vertical mills also have a smaller footprint and require less maintenance, making them more suitable for ...
