In recent years, foreign opposition grinding, especially into the application of cement mill increased significantly. Actually, the LUM vertical roller mill is representative of a new generation of cement grinding, especially cement vertical roller mill finish grinding technology, to process system has the advantages of simple process, low unit power consumption, cement products, stable quality and convenient operation has many advantages, has been in the cement industry has developed rapidly. Abroad, especially in Europe and the United States and other countries in the cement vertical roller mill finishing grinding technology has been very mature, there have been a large number of sales performance.
2004 Taiwan lucky cement in Vietnam to establish a 5000 tons / day of cement production line, the equipment adopts two sets of cement vertical roller mill, tons of product consumption in the cement plant to 78-80KWh/t.
In 2006 the United Arab Emirates 10000TPD cement production line, India 10000
TPD cement production line put into operation, all the vertical roller mill, respectively grinding of raw materials, coal, cement, have made good performance.
What are the reasons of hindering the development of cement mill in Chinese?
With the development of the vertical roller mill technology, more and more foreign cement companies eliminated the traditional ball mill, began to use cement vertical mill, but in China, cement vertical roller mill not real spread, what is what reason to hinder the cement vertical mill in China's development
Habits
In China, ball mill and roller press as the traditional grinding equipment, there has been a more than 100 years of history, especially the low cost of ball mill, cement sphericity Gauguin is cement factory on the very popular. With the development of the times, although the ball mill in the use process of environmental harm larger, but due to the exhaustion of the time-consuming of lack of funds and technical transformation, most cement companies still choose ball mill for grinding equipment.
"One-sided understanding of the particle shape is not good, water"
Some cement factory by speech "cement vertical mill production of refined grain shape, large water demand" effect, understanding of cement vertical mill is not comprehensive. In fact, experts pointed out that some professional manufacturers through adjustment of the grinding disk and the grinding roller design can be a very good solve the cement vertical mill out spherical finished product is not good, particle shape distribution problems of narrow, so as to improve the vertical mill cement workability.
