Detailed Product Description
Its are widely to apply in cement building materials, power industry. During the process of production, under the conditions of single warehouse as well as normal mining: 40 grams are needed by per tonne of cement as national standard; 30 grams as our enterprise; according to the feedback of the patrons, that's only need 18-19grams.
