The present invention provides a control method for superfine powder grinding industrial waste slag in an energy-saving and environmental-friendly type of closed cycle with high yield and the apparatus for the same. The method combines a drying process and a powder grinding process, adopts an in-line monitoring process, automatically adjusts and controls the operating parameters. Therefore, the invention changes the conventional open cycle into a closed cycle, shortens the cycle, achieves the automatic control and adjustment of the operating parameters, and obtains the superfine product with high yield. So the invention enhances the application value of industrial waste slag, extends the applicable field of industrial waste slag, and increases the extra value of final product. The apparatus primarily adds a wind sweeping drying grinder, an in-line laser particle detector, and an automatic control device, furthermore selects a screener and a deduster with high efficiency and product quality and therefore needs less space, investment and energy consumption, improves the work efficiency, the quality of the product and overall efficiency. The apparatus can automatically adjust and control the operating parameters, improve the physical and chemical characteristics of industrial waste slag, and change the industrial waste slag to industrial additive or admixture with good performance; therefore it has good economic and social benefit.
