As shown in Table 1, when not adding grinding aid, the screen over-size of silicate cement 0.08mm square hole sieve is 3.8%, and after using trolamine grinding aid, screen over-size is 2.46%, after using the gained grinding aid of the present invention of various dose, screen over-size drops to 1.41%, 1.39%, and the median size of B, C two groups is also significantly less than A, D two groups, illustrates that the result of use of gained grinding aid of the present invention is better, and when volume is 0.08%, effect is particularly remarkable.
Material combination selected by the present invention is appropriate, and the grinding-aid effect for silicate cement is excellent, effectively can reduce particle and mutually assemble and adhesion phenomenon in use procedure, improves the efficiency of pulverizer, reduces energy consumption, reduces plant produced cost.
It should be pointed out that embodiment is the more representational example of the present invention, obvious technical scheme of the present invention is not limited to above-described embodiment, can also have a lot of distortion.Those of ordinary skill in the art, with the present invention clear and definite disclosed or according to undoubted the obtaining of the written description of file, the claimed scope of this patent all should be thought.
