Ways To Improve Efficiency Compared With Traditional Mill

Cement mill is potentially expensive and can grind mixture particles to as small as enormously increasing surface is and reaction rates.The grinding works on principle of critical speed.The critical speed can be understood as that speed after which the steel balls (which is responsible for the grinding of particles) start rotating along the direction of the cylindrical device; thus causing no further grinding.Cement mill is most efficient when the maximum feed size is less than 2′ and iron contamination is not a factor.These mills are sized from 2hp to 450hp for wet grinding and from 2hp to 500hp for dry grinding.Particles of different sizes and densities, when revolved in a cone will classify themselves with the largest pieces at the point of the greatest diameter.The shape of the conical cement mill provides a classifying action within the mill resulting in increased efficiency and lower power consumption.Cement mill is normally operated at around 75% of critical speed, so a mill with diameter 5 meters will turn at around 14 rpm.The mill is usually divided into at least two chambers, allowing the use of different sizes of grinding media.Large balls are used at the inlet, to crush clinker nodules (which can be over 25 mm in diameter).Ball diameter here is in the range 60-80 mm.In a two-chamber mill, the media in the second chamber is typically in the range 15-40 mm, although media down to 5 mm is sometimes encountered.Hammer crusher:http://www.Crusher-machine.Com/3.Html vibrating screen:http://www.Hxjqchina.Com/product-list_56.Html the way to improve its efficiency 1.Add a fine crusher in front of the cement mill.The fine crusher decreases the particle size of materials that will be put into the cement mill, which reduces the load of grinding system.2.Improve the grinding system of cement mill, improve the grinding efficiency.Improving the grinding efficiency, the most direct benefit is getting the finished powder maximum in time, reducing the rate of cement products back to the flour yield, decreasing the load of cement mill.3.Add a high efficiency separator.The small particle size of raw material is, the high grinding efficiency is.If the grinding efficiency is low, not only the output of cement mill, but also the quality of cement will be influenced.All of the three methods introduced by hongxing's engineer are effective to improve the output of cement mill.The relationship between the three methods is that crushing before grinding is the premise, choosing powder after grinding is the guarantee, and transformation of cement mill is the fundamental.Cement mill:http://www.Hx-crusher.Com/cement_production_line.Html.
