Technical Field

[0001] The utility model relates to the technical field of cement grinding aids, in particular to a cement grinding aid pouring trough. Background Art

[0002] In the grinding process of cement clinker, adding a small amount of additional substances can significantly improve the grinding efficiency or reduce energy consumption without damaging the performance of cement. This kind of chemical additive is generally called cement grinding aid. Cement grinding aid is a chemical additive that improves the grinding effect and performance of cement. It can significantly increase the cement output per hour, the strength of cement at all ages, and improve its fluidity. Cement grinding aid can greatly reduce the electrostatic adsorption ball phenomenon formed during the grinding process, and can reduce the tendency of ultrafine particles formed during the grinding process to aggregate again. Cement grinding aid can also significantly improve the fluidity of cement, improve the grinding effect of the mill and the powder selection efficiency of the powder selector, thereby reducing the energy consumption of grinding. Cement produced with grinding aids has a lower compaction and agglomeration tendency, which is beneficial to the loading and unloading of cement and can reduce the wall hanging phenomenon of cement warehouse. When producing cement grinding aids, it is necessary to inject a variety of liquid raw materials into the pouring trough and add water for mixing and processing.
