[0002] Cement grinding aid is a chemical additive that improves the grinding effect and performance of cement. Cement grinding aid can also significantly improve cement fluidity, improve the grinding effect of the mill and the powder selection efficiency of the powder classifier, thereby reducing grinding energy consumption.

The device fixes the dust collection device to the bottom end of the support frame through a supporting bottom column, and installs a dust collection bag through the top of the dust collection chamber. Then the raw materials are put into the reaction bin from the feed port for reaction, and then the grinding aid enters the dust collection chamber through the discharge pipe and the dust collection bag. The conveyor belt transports the grinding aid that falls to the bottom of the dust collection chamber to the discharge port. At the same time, the suction fan sucks the dust into the dust reduction chamber through the ventilation hole, and the suction fan is started by an external controller; after the dust enters the dust reduction chamber, the water spray head sprays water to the dust reduction chamber through an external water pipe, and adsorbs the dust with water mist, thereby achieving the purpose of dust reduction.
