5 · the ability to use cheap natural products local sand slag ore as grinding media These features distinguish stirred mills as fundamentally different from both ball mills and Tower Mills as demonstrated by Tables 1 and 2 Table 1 Typical Power Intensities of different Grinding Devices Table 1 Power Intensity of Different Grinding Devices
There are so many types of cement mills that can be selected for slag grinding plants Vertical mills are generally used for grinding slag powder A vertical cement mill is also called a vertical slag mill It has the advantages of high production capacity low energy consumption and environmental protection in the field of slag powder grinding
·600 000t/a slag grinding plant Energy consumption 450 000t/a slag grinding plant Energy consumption 300 000t/a slag grinding plant Energy consumption; Output t/h 105 65 50 Annual output ×10 000 tons 60 45 30 Total Power（KW） 5400 3770 2860 The power at 10KV（KW） 4400 3140 2230 Transformer specifications 1000KVA 630KVA
·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
·The specifications and materials of the grinding body of the ball mill can be adjusted according to the material properties which enables the ball mill to grind steel slag with high hardness but the unit power consumption for grinding steel slag powder with a specific surface area of 400 m2/kg is about 100 kW·h/t
Slag material has similar hydraulic properties to cement and as such has shown to be an excellent substitute for raw clinker materials To date there have been some drawbacks utilizing slag in cement manufacturing including higher specific power consumption in the finished grinding area and increased handling and maintenance circuit wear
·The present literature review explores the energy efficient ultrafine grinding of particles using stirred mills The review provides an overview of the different techniques for size reduction and the impact of energy requirements on the choice of stirred mills It also discusses the factors including the design operating parameters and feed material properties
·Grinding slag for cement replacement requires only about 25% of the energy needed to manufacture normal Portland cement Typically in a direct comparison the belt bucket elevator has demonstrated a reduction of 75% in energy consumption as shown in Graph 1 Not only is the bucket elevator energy efficient it is also less prone to wear in
·and specific power consumption on the main drive see Figure 1 Specific power consumption can be also reduced by using wet slag in an intergrinding process A material containing 40 per cent slag with a moisture content of per cent shows power consumption during intergrinding comparable to power use during separate grinding see Figure 2
