Title:
CLOSED CYCLE SUPERFINE AND HIGH YIELD GRINDING CONTROL METHOD AND APPARATUS OF SAVING ENERGY AND ENVIRONMENTAL FRIENDLY TYPE FOR INDUSTRIAL WASTE SLAG
Document Type and Number:
WIPO Patent Application WO/2007/009321
Kind Code:
A1
Abstract:
The present invention provides a closed cycle superfine and high yield grinding
control method and apparatus of saving energy and environmental friendly type
for industrial waste slag. The method combines a drying step and a fine grinding
step, adopts an online monitoring step, automatically adjusts and controls
process parameters. Therefore, the invention changes the opened process in
the prior art into the closed cycle process, shortens the process flow, achieves
automatically controlling and adjusting the process parameters, and attains
the object of superfine grinding and high yield. So the invention enhances the
application value of industrial waste slag, extends the application range of
industrial waste slag, and increases the extra value of final product. The apparatus
primarily adds a wind sweeping drying grinding mill, an in-line laser particle
detector, and an automatic control device, furthermore selects a fine classifier
of high efficiency and a dedustor, so it can reduce occupied floor area, investment
and energy consumption, and can increase efficiency and product quality. The
apparatus can automatically adjust and control process parameters, improve
the physical and chemical performance of industrial waste slag, and change the
industrial waste slag to industrial additive or admixture of good performance,
therefore it has good economic and social benefit.
