Steel plant blast furnace slag is discharged waste in the production process. At present, the
slag into the slag powder ground, the same amount instead of cement, either turning waste
into treasure, and can reduce production of cement needed for mining resources is an
important way to develop recycling economy and achieve sustainable development. Slag powder
is a new type of high-strength concrete admixture, high-quality cement admixture, the raw
material is metallurgical industry blast furnace slag, is the use of a new type of
environmentally friendly industrial waste products. Over the past decade, mostly large steel
companies have invested in building slag grinding production lines, the slag powder project
as a priority the development of non-steel industry.
Slag grinding can be Vertical Roller Mill for Slag Grinding, roller press, ball
mill, vibration mill four kinds of finish grinding process, or the use of vertical mill +
mill, roller mill joint press + grinding process, where vertical mill The most common
production process for each steel company preferred. The host device is a vertical roller
mill grinding process and baghouse. Terminal Equipment slag grinding system is baghouse.
Baghouse dust has collected the finished product and environmental dual function, plays a
vital role in the grinding system.
To ensure the slag powder fineness and energy conservation needs, slag grinding system mainly
chosen Vertical Roller Mill processes. Compared with other processes, Vertical Roller Mill
for Slag Grinding process has significant energy saving, good drying effect, the advantages
of small footprint and construction investment and other provinces. In recent years, due to
the vertical mill in the area of raw material grinding and coal preparation and the
continuous development of breakthrough materials science, hydraulic technology, automatic
control, and gradually overcome...
