1. Small grinding experiment :to test this product and the applicability of the raw materials of cement production enterprises should do first a small grinding test sample to do the following three groups:
1) with the ratio of production to do a comparison sample, record the specific surface area of cement to 350m2 / kg of the time;
2) with the production of quality cement ratio by adding 1 ~ 1.3 ¡ë of the grinding aids, grinding in the same time, measuring the surface area and intensity;
3) the production ratio in the clinker by 5-7%, mixed material added, grinding in the same time, measuring the surface area and strength and then compare the strength and fineness of the election satisfactory grinding aids and the production ratio, followed by bigger and grinding test.
2. large grinding test :as a laboratory grinding mill and the cement industry grinding body size distribution and logistics conditions are different between the two results of the assessment may also vary. The small grinding tests had confirmed the technical and economic benefits can be increased, it may produce bigger and grinding test. Daruma test time is generally a frequency of (8 ~ 12 hours), boot cast material 1 ~ 2 hours for a blank sample by adding grinding aids 1 ~ 2h after the grinding time for the wash, wash mill after the end of every half hour or an hours of sampling time, each taking concrete samples have to be careful and meticulous analysis. Finally, the mixing of the sample strength test done until 3 days, 28 days strength came out, it would show the business benefits for cement grinding aids. Trial production of the product test data to assess the grinding aids of the most reliable data.
