As shown in Table 1, gained of the present invention is used to improve the additive of cement usefulness, 80 ��m of screen over-sizes of cement drop to 1.43% and 1.35% respectively, thus improve the fineness of cement, strengthen its mobile performance, improving the efficiency of grinding, additionally its comprcssive strength and rupture strength are also remarkably reinforced, and improve the quality of cement.
In actual production process, with identical machine pulverizing cement, when not using gained additive of the present invention, flour mill yield is 14.8t/h, and after using gained additive of the present invention, the yield of flour mill is 21.2t/h, efficiency improves 43.2%, therefore can improve yield, reduce loss, reduce production cost.
It should be pointed out that, the detailed description of the invention more representational example that is the present invention, it is clear that technical scheme is not limited to above-described embodiment, it is also possible to have many variations. Those of ordinary skill in the art, with the present invention undoubted the obtaining of clearly disclosed or according to file written description, be all considered as this patent scope of the claimed.
