Trial steps of cement grinding aids you don't know

Grinding AIDS play an increasingly important role in the cement industry. How should enterprises try out various grinding aids? Huahai, Hebei Province, pointed out that the trial steps of cement grinding aids are as follows:

1. First, the main purpose of using grinding aids and the grinding process and equipment characteristics of our factory should be told to the grinding aids supplier truthfully, and the grinding aids varieties should be recommended by the supplier. According to the supplier's anticipated quantity and price, as well as the comparison of economic benefits after joining, determine whether it is necessary to carry out the test.

2. Feasibility of laboratory test. Small grinding test can control the amount of grinding aids accurately, and the changes of various cement performance indicators can also be accurately obtained. But it is different from the production site after all.

3. Industrial production test, this kind of experiment workload is large, but it is very necessary. After the ball mill runs stably, after adding the grinding aids accurately through calculation (such as using solid additives, measuring facilities are more complex), we can observe whether the load of the hoist of the ball mill increases, the grinding sound becomes brittle, and the feed quantity of the ball mill can increase. Without these performances, the experiment would not have to go on. Record the following data in operation: feed quantity of ball mill, system power consumption, cycle load, product temperature, equipment power, product fineness and chemical analysis of finished products. After the ball mill stops abrasively, the feed height, the relative height of the steel ball to the feed surface, the observation of the partition board, the lining board, the steel ball surface and the material bonding condition, and take the sample to make the sieving curve. Various parameters of ball mill operation are adjusted to achieve new optimal balance. The cement strength and other properties were tested after adding grinding aids.

4. Comprehensive evaluation of economic benefits before and after the use of grinding aids to determine the feasibility of using a grinding aids.
