With the rapid development of building industry, the sand has a big demand for building engineering. The river sand, as a local resource, can not reborn again at a short time with a phenomenon of decreasing of natural sand in the world even no natural sand existing in some area. The conflict between the concrete supply and need with high price of natural sand influences the progress of engineering building. The commercial ready-mixed concrete is now at a corresponding lower content in the world, which has a promotion room. When the commercial concrete is two times than before, the corresponding manufacture processing equipment will has a two times demand than before also. Concrete means that gelled material cements the aggregate into a whole engineering composite. In general, concrete means that cement as the gelled material with sand and stone as aggregate mix with sand according to a scale, after mixing, molding and conservation, then cement concrete is done. And the sand and stone production should need the process of Vertical shaft Impact Crusher. Because it has a strict requirement for commercial concrete of sand and aggregate, which the general Vertical shaft Impact Crusher cannot achieve its standard. Liming Heavy Industry manufacturing the number three generation can meet the requirement of concrete aggregate no matter it is fine or coarse crushing.
