水泥业采用沟槽式衬板的效果
采用沟槽式衬板的效果
Effect of using grooved lining
仅以水泥业为例。
Take the cement industry as an example.
我国的水泥产量为世界第一,但总体品质不高。主要表现为早期强度偏低。而早期强度偏低的根本原因有二:一是原材料的质量不高,买中含有不同比例的混合料,混合料越多,品质越低;二是产品的细度不移,即粒度太粗,粒度越粗,品质越低。
China's cement output is the first in the world, but the overall quality is not high. The main manifestation is low early strength. There are two basic reasons for the low early strength: first, the quality of raw materials is not high, and the more the mixtures are, the lower the quality; second, the fineness of products is not shifted, that is, the coarser the particle size, the lower the quality.
从2001年1月1日,我国的水泥标号与国际水泥标号采用同一标准(ISO)。这无疑对我国水泥业是一个严峻又必须接受的考验。除了严格把握原材料本身的质量之外,最简捷的方法就是采用沟槽式衬板以替换普通衬板。目前,国内有800余家水泥厂、火电厂和选矿厂在千余台φ1.5-5.7m的磨机上应用沟槽衬板,其应用效果(与普通衬板相比)较好。
Since January 1, 2001, the same standard (ISO) has been adopted in China's cement labeling and international cement labeling. This is undoubtedly a severe and necessary test for China's cement industry. In addition to strictly grasp the quality of raw materials, the most simple way is to use grooved lining plate to replace the ordinary lining plate. At present, more than 800 cement factories, thermal power plants and concentrators in China have applied groove lining board on more than 1000 grinders with a diameter of 1.5-5.7m, and its application effect (compared with ordinary lining board) is better.
