than ball mills, even if the ball mill is combined with a roller press. This and further arguments led to the increased share of VRM for the grinding of finished cement. Taking into account that VRM usually have a bigger output than ball mills, it can be declared that the major part of the cement production with newly installed mills comes from ...

1.5.1. The Ball Mill. Ball mills or tubular mills are built with diameters up to 6.0 meters and lengths up to 20 meters; the drive ratings today are as high as 10,000 kW with stable operation, and maintenance of a ball mill is relatively simple . The maintenance cost and the capital cost are relatively low compared to other technologies.

A typical comparison of three competing technologies is given in Table 1, demonstrating that an efficient ball mill/third-generation separator, CKP/ball mill/third-generation separator and vertical mill on a typical 4000Blaine limestone cement show little overall difference in energy consumption.

Answer (1 of 5): The former has better performance, more functions and lower consumption. Customers are also focused on the use of equipment for grinding various materials. Ball mill crusher can meet users' ideal standards in the processing of various m etal ores, non-ferrous metals and ferrous ...

In a ball mill, the grinding process takes place by impact and attrition. On the other hand, a vertical roller mill exposes a bed of material to a pressure high enough to fracture the individual particles in the bed. This process creates a stable and consistent grinding …

Ball mills are factory made and transported to the plant site of the buyer while VRM is built on the site of the cement plant. This helps to reduce cost and complicated logistics issues. The equipment cost is, however, higher for a VRM than a ball mill. So these are the pros and cons of the two technologies and a cement manufacturing company ...

Technical cost is also an important factor that affects the price of vertical mills. The higher the investment in technology, the more significant the performance of the equipment, the better the use effect, and the greater the profit for users, but the same cost consumption will be greater and the price will be higher; on the contrary, the price of equipment with low technical content Lower ...

As the Vertical Roller Mill (VRM) becomes more widely accepted for new cement grinding systems differences in installed costs between a VRM and a ball mill system are more frequently discussed.

mill used, i.e. ball mill or vertical roller mill. Typically, the motor of the ball mill consumes about 14 - 15 kWh/ ton of raw mix whereas the VRM motor uses 7 - 8 kWh/ ton. On an overall basis, VRM consumes about 20 % lower specific energy than conventional closed circuit ball mills and is being

In the. 54 simulated twostage openclosed grinding circuit. a closed circuit mill, is diverted to a mill operating in open circuit. media grinding mills, such as ball, rod, autogenous, or pebble mills, is a significant waste of energy differences in particle density and …

Typical types of mill used in ore beneficiation are autogenous (AG) and semi-autogenous (SAG) mills together with ball mills to, for example, obtain particle sizes smaller than 100 µm. One process variation that has become increasingly established in recent years is the combination of AG or SAG mill with a ball mill and a downstream agitated ...

Figure 2: Comparison of PSD of CEM I 52.5 ground in a VRM and average ball mill (mean of 160 single measurements) n As an energy-intensive sector, the cement industry has always made efforts to reduce its energy requirements with the goal of cutting the high fuel energy costs involved. In the past decades, high fuel costs and environmental issues

The VRM offers several benefits compared to the ball mill in regards to operating costs and flexibility. ... The typical energy use for roller mills lies within 18 to 20 kWh/t clinker, depending ...

Ball mills, that are commonly used for finish grinding, have high energy demands, consuming up to 30-42 kWh/t clinker depending on the fineness of the cement. Complete replacement of ball mills by vertical roller mills (VRMs) with an integral separator – as opposed to the use of VRMs as pre-grinding to ball mills – is regarded as a breakthrough. Use of VRM in finish grinding combines ...

The mill has benefits in reducing power consumption by circa-15%, no ball charge grinding media, higher flotation recovery and can be ramped up and down in response to the availability of low-cost renewable energy."
