At current, there are numerous processes and solutions of your Vertical Roller Mill manufacturing. Based on the various possibilities in the grinding tools it could be divided into open circuit grinding, circle circuit grinding and pre-grinding. Open stream grinding system. open circuit grinding method utilizes the tube mill, generating the different hardness and distinct sizes of grinding mixture sent during the Vertical Roller Mill. The particle size ratio of this approach is much better than that of circuit grinding approach, meanwhile the strength is increased. Even so because of the in excess of grinding of mixture, such type of grinding system will produce a large false precise surface place, at the same time the more than grinding will shell out a good deal of energy and time and maximize the work out in futility.
Circle circuit grinding course of action. Circuit grinding procedure is usually to make the powder through the Vertical Roller Mill grinding deliver to theclassifier for sorting, The fine powder reaches the fineness degree is called cement completed solutions, and after that coarse powder is sent for the head for secondary grinding. Circuit grinding is conducive for the regulation and handle of solution fineness and temperature, its grinding efficiency is about 10-20% greater than that of your open circuit grinding procedure, the finer with the completed product fineness, the extra apparent of your benefits. On the other hand, the grinding approach features a downside, that is, the 10-40um average particle diameter on the obtained cement items certainly greater, 5-20um or significantly less the average particle dimension drastically decreased, this technique leads to unreasonable particle dimension distribution in the cement, and will not maximize the strength with the clinker.
Pre-grinding process. existing, China's new dry processcement manufacturing linecommonly makes use of the pre-grinding procedure that is composed by roller press machine andball mill. The power-saving degree of your process improvements in accordance to your size from the electrical power consumption, its conserving effect is outstanding. Nevertheless, because of the degree of China's industry lags behind, so the roller press on the roll press machine can only be maintained at about 80Mpa, the energy consumption in the entire technique is greater than that of foreign countries. For that reason, the vitality conserving area of grinding course of action in China is still raising.
