Description

Technical Field

[0001] The utility model relates to the technical field of cement grinding aid production, in particular to a cement grinding aid reaction kettle. Background Art

[0002] As we all know, in the process of grinding cement clinker, adding a small amount of additional substances can significantly improve grinding efficiency and reduce energy consumption without affecting the original properties of cement. Such chemical additives are generally called cement grinding aids. The cement grinding aid reactor currently used has certain defects, lacking a material leakage prevention mechanism. The material is discharged through a control valve. When the sealing ring inside the control valve is damaged, the material is easy to leak out, resulting in material waste.

[0003] After searching, a cement grinding aid reactor disclosed in application number CN201920511027.5 is disclosed, in which a motor mounting bracket is arranged at the top center of the reactor cover, a reduction motor is installed on the top of the motor mounting bracket, and an agitator is connected to the bottom power output end of the reduction motor. The agitator is located in the inner cavity of the reactor body. Therefore, the agitator in the existing cement grinding aid reactor can only rotate to stir the cement grinding aid in the reactor, resulting in low stirring efficiency. Utility Model Content
