The manufacture of GGBS mainly involves the processes of cooling of molten slag through highpressure water jets, drying, and grinding in a rotating ball mill [5, 9]. These operations consume less energy as compared to the clinkering process of cement manufacturing [ 10 ].
GGBS is produced by grinding Granulated Blastfurnace Slag to a controlled fineness. There are a number of different methods of grinding granulated blastfurnace slag. Traditionally, standard ball mills have been used, but since the early 2000s the use of roller presses and vertical mills has increased.
The granulated slag is further processed by drying and then grinding in a rotating ball mill to a very fine powder, which is GGBS. GGBS can be used as a direct replacement for ordinary cement on onetoone basis by weight. Replacement rates for GGBS vary from 30% to up to 85%. Generally 50% is used in most applications.

The power consumption of raw material vertical mill system is /t lower than ball mill, that is to say: in one year, a 5000TPD cement plant can save energy in clinker grinding system: /t * 5000t/d * 300d=14,550,000 kWh, that means the cement plant clinker grinding system can save 14,550,000 kWh electricity one year.
The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.

The determination of unit output is very important, directly related to equipment selection. Equipment selection should take full account of the following factors: (1) The slag vertical mill is not a device that can run continuously for a long time. It is necessary to stop the repair every 1500~1800h, usually 7 days for each repair and 35 days for the whole year.
Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall energy use and media ...
GRMS series slag (slag product applications) vertical mill can reduce power consumption effectively in the process of production as the core equipment of production line. Meanwhile, mill internal is negative pressure in process, which produces almost no dust during operation, lower noise and pollution than traditional tube mill.

At present, the production line of slag powder vertical mill has reached an annual output of more than 2 million tons. When the output of slag is below 2 million tons per year, it is recommended that the steel mill choose a production line.
Alomari et al., 2019). Ultrafine grinding is considered as an energy intensive process. The wet grinding performance using vertical stirred mill is investigated through testing the most affecting factors such as stirring speed, feed size, solid concentration and grinding time. The milling performance was evaluated
