Description

Technical Field

[0001] The utility model belongs to the technical field of cement grinding aids, and in particular relates to a cement grinding aid anti-sedimentation storage tank. Background Art

[0002] In the grinding process of cement clinker, adding a small amount of additional substances (liquid or solid 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. The storage tank is a tank used to store cement grinding aids. At present, the storage tank has the following common defects:

[0003] When cement grinding aids are stored in traditional storage tanks, the method of preventing them from settling is mainly to stir the inside of the storage tank through a stirring rod, etc., so as to achieve the stirring and anti-sedimentation effect of the liquid. However, the larger sediment at the bottom will not be completely mixed with the liquid until a long stirring time, which will lead to an increase in the overall anti-sedimentation stirring time, thereby reducing the anti-sedimentation operation effect of the overall storage tank.
