The global Ball Mill (Mining) market was valued at US Mn in 2018 and is projected to increase significantly at a CAGR of % from 2019 to 2028. Ball Mill (Mining) Market Scope: By type, the market is segmented into Wet grinding Ball Mill and Dry grinding Ball Mill. By application, the market is divided into Metal Mining and Mineral Mining.
Over the last three decades the vertical roller mill has become the preferred 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,
Energy and exergy data for VRM is scarce but when compared with an industrialscale ball mill, the first law efficiency of the ball mill (%) was similar to the VRM (%) of this study, however, the second law efficiency of the ball mill (%) was significantly lower than the second law efficiency of the VRM (%).
Different specification of roller mill so the K1 is different. K1 of Loesche Mill series roller mill is and for Atox Mill is 7 and for. MPS Mills is D is the table diameter. Example for MPS 2800 mill with table dia G = * = ~ 50 tph. ffVRM Hydraulic Operation.
The vertical roller mill itself is equipped with a powder concentrator, which can remove fine powder in time, reduce the phenomenon of overgrinding and improve the grinding efficiency. The vertical roller mill is less power consuming. The energy consumption of a vertical roller mill is around 75% of that of a ball mill of the same capacity.

Promising results obtained from cement industry encouraged the test studies on mineral grinding. van Drunick et al. (2010) presented VRM pilot plant test results where zinc ore was ground. In his study it was concluded that the total specific energy of the AG/SAGball mill circuit, which was kWh/t, was reduced to kWh/t by using VRM.

The VRM technology was introduced in the mid'90s for grinding clinker and slag by LOESCHE (Schaefer, 2001). Fig. 1 illustrates the grinding parts of a Loesche vertical roller mill. The grinding material is comminuted in the Loesche roller grinding mill between the rotating horizontal grinding track and stationary grinding rollers.
The discharge port of the wet ball mill is trumpetshaped and has a builtin screw device for easy discharge. Most of the ball mills sold on the market are wet ball mills with high grinding fineness and a good beneficiation effect. 3. Matters needing attention in the process of choosing dry and wet grinding
The global vertical roller mill market is projected to grow at a CAGR of % from 2017 to 2030. The growth of the global vertical roller mill market can be attributed to the increasing demand for cement and minerals in developing countries and the growing awareness of energyefficient technologies among consumers.
With the introduction of the high compression machines such as High Pressure Grinding Rolls (HPGR), Vertical Roller Mills (VRM) and Horomills, efficiency of the grinding circuits was improved in terms of energy and downstream effects. Among these devices, vertical roller mills have an important position in cement and mining industry.
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 EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, whether hardfacing is applied.
Vertical Roller Mill (VRM), a cutting edge technology, can be installed to grind the hard, nodular clinker from the cement kiln instead of inefficient ball mills that can save up to 15% energy [63]. Inclusion of flexible speed drive used for cooling purpose can further reduce electricity consumption.
For VRM the production capacity denotes both the capacity of grinding and drying of mill. The grindability affects the capacity of grinding, type of mill and roller pressure. The capacity of the mill is calculated Using G K * D Where, G is capacity of the mill, K1 is roller mill coefficient and D is table diameter. 2. PROCESS CONTROL OF VRM
