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 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.
The available capacities are from 500 tons to 3,000 tons per day. A vertical roller mill combines intermediate crushing, grinding, drying, separating conveying processes. While grinding the slag, the fineness will be as per Blaine > 4,200 cm2/gram. The initial moisture of 15% in the slag will be reduced to % in the process.

of the grinding material is poor; (4) The system power consumption is 80kwh/t, and the roller press system has a large circulation amount, and it has to be transported by the belt conveyor and the lifting conveyor, so the system is dusty; (5) System operation rate: 85%90% Vertical mill process features: (1) The structure is simple, the vertical mill installation is adopted, the floor space is ...
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.
The number of revolutions controls the power consumption for the grinding of media. Hence, it has a moderately smaller power density. ... The concept of grinding media movement within a stirred media mill with a vertical grinding chamber was ... Yoon, R. Effect of operating parameters in stirred ball mill grinding of coal. Powder Technol. 1989 ...
The mill power draw is measured by a torque rod situated in line with the main drive shaft. The specific power consumption ΔeVRM200 in J/kg could be calculated by the control system according to Eq. ... The paper aimed to provide traceable measurement results to compare the energy consumption for grinding only of ball mills and vertical roller ...
For an chaeng vertical mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, whether hardfacing is applied. If hardfacing is not applied the cost is as for the ball mill, EUR per ton of cement. If hardfacing is applied, the corresponding figure will be EUR per ton of cement.
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.

F irst it is important to know the types [13] of cement mills used in cement plant to grind the clinker (main Substance in cement production) to produce ordinary Portland cement (opc), mainly there are four types of mills: Horizontal Ball Mill in Closed Circuit, Vertical Roller Mill and other less using like Horo Mill, Vertical Ball Mill ...
In order to simulate the industrial ball milling operation, the feed to the mill consisted of slag with natural size distribution less than 850 μm. ... the average energy consumption can be as ...
GRMS series slag vertical mill can reduce power consumption effectively in the process of production as the core equipment of production line. Meanwhile, because it is a negative pressure operation, vertical mill produces almost no dust during operation, low noise and pollution than traditional tube mill. 3. Mature general contrasting scheme
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.
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 ...
2. The production line system power consumption in 40KWh / t. Ball mill energy consumption is too high for many cement companies had a headache, and the new vertical mill equipment has become the most internationally recognized technology leader in energy saving grinding equipment, standalone energy consumption can be reduced more than 30%! 3.
