[0002] During the cement production process, when the cement kiln is calcining cement clinker, external additives are added to improve the stability and quality of the finished cement. Among them, dicalcium silicate is an important additive to increase the porosity of the finished cement, maintain room temperature stability and alkali activity.

[0003] The existing dicalcium silicate stabilization and activation device lacks a temperature control device to control the temperature of dicalcium silicate during use, which easily reduces the activation effect of dicalcium silicate. During the addition process, the uniformity of addition is poor, which reduces the bonding effect between cement clinker and dicalcium silicate. In addition, the addition structure is insufficient, which is not conducive to adding water and other catalysts to dilute the concentration of dicalcium silicate, resulting in a decrease in the activation effect of dicalcium silicate on cement clinker.

[0004] Therefore, those skilled in the art provide a temperature-controllable dicalcium silicate stabilization and activation device to solve the problems raised in the above background technology. Utility Model Content
