The main ways of utilization of steel slag with high value of resources is steel slag grinding processing, to be used as cement, concrete admixture. Because the steel slag of high hardness, poor grindability, so in the processing of steel slag grinding equipment has put forward higher requirements. At present, the vertical roller mill by the industry's attention, has been recognized at home and abroad for the steel slag processing equipment preferred. But after field survey found, the application rate of Chinese steel slag vertical roller mill is still relatively low, investigate its reason, is no more than the general iron and steel factory, building materials factory on the use of steel slag vertical mill lack confidence.

It is understood, vertical roller mill grinding process requirements into the grinding slag particle size is small, the iron content of less, otherwise it will cause serious wear and vibration phenomenon, resulting in production is not up to the standard, unstable operation, short service life of parts.

Aiming at this problem, the first steel slag "pretreatment selected iron + vertical mill" closed-circuit grinding process, grinding of steel slag in the entry before the pre grinding processing. The reliability and the grinding efficiency is better than the ordinary milling and other coarse grinding device special for pre grinding equipment with the process, the original steel slag materials effectively coarse grinding and dressing iron, thus ensuring low energy consumption, after the slag grinding stage vertical low wear, stable operation. Mechanical slag "pretreatment selected iron + vertical mill" closed-circuit grinding process is another innovation of steel slag grinding processing, completely change the situation of traditional tube mill process is unsatisfactory, and make up for the defects and deficiencies of single steel slag vertical mill grinding process,

The process has the following unique advantages
