an important role, but in the manufacture of concrete, cementitious materials used in cement
--- resource consumption, energy consumption and environmental pollution problem is very
prominent. How to use less clinker, mostly mixed industrial waste (slag, fly ash, etc.) for
mixed material, or the use of Vertical Roller Mill for Slag Grinding going to the slag into
flour for fine mineral admixtures used directly in the production of concrete, concrete
sustainable development and reduce the cost of production of the important technical route.
Many research results show that the production of slag cement, slag as a quality mix of
materials, up to 60% ash, slag is ground to a specific surface area 400-500m2/kg, fine
admixture for concrete, can be replaced by 20% -40% of cement, concrete strength class up to
C60, If slag ground to a specific surface area 600m2/kg, C80 concrete strength can be
achieved more. Thus, the slag has a very good potential activity.
Slag is Mainly from mining crushing product,Under normal circumstances, the first step is to
crush the minerals by early break, this time used is known to everyone of the crusher, the
crusher with jaw crusher machine, crusher ..... etc. The jaw crusher made by jaw crusher
manufacturers in india is of high-strength manganese steel, a shape casting, with wear,
compression, long life and other advantages. Jaw crusher is mainly used for no more than 320
MPa compressive strength of
