[0002] Cement additives are needed during cement production. Cement additives refer to additives added during the application of cement to improve or achieve various properties, such as quick drying or strengthening, such as reducing water content, such as retarding with retarders. Common cement additives are in two forms: liquid and powder (solid). When cement additives were first used, it was to save cement. Now, with the continuous development of construction technology, adding cement additives has become the main measure to improve the performance of cement, which can significantly increase the output of the mill, or improve product quality, or reduce grinding power consumption. Since cement additives are one of the necessary materials in construction technology, the technology for preparing them is also an essential process in construction technology.

[0003] At present, a Chinese patent discloses a precipitation device for producing cement additives, with the application number 2022210959630. By setting a motor, a rotating shaft and a stirring rod, large solid blocks and lumps in the cement additives can be crushed. A filter plate is set to refine and filter the cement additives to prevent large solid blocks from mixing into the cement additives. Universal wheels are set to make it more convenient to move the device.

[0004] Combined with the above disclosed technical solution, when crushing solid lumps, the rotation of the stirring rod in the stirring box has stirring dead corners, and it is difficult to completely crush the solid lumps, resulting in more solid lumps accumulating at the dead corners, affecting the precipitation efficiency.
