CAS 8061-51-6 Sodium Lignosulfonate Cement Grinding Aid 3804000090

Sodium lignosulfonate is used as cement grinding aid HS COAD 3804000090

Sodium Lignonsulphonate :

Cement production process, in order to improve the grinding efficiency, reduce energy consumption, generally added in the grinding process of bending aid, under the same fineness conditions, shorten the grinding time, reduce energy consumption, increase the output, or in the same grinding time under the premise, improve the cement fineness and strength, but also improve the fluidity of powder.

Lignin can be used as cement grinding agent, sodium lignosulfonate is a kind of anionic surfactant, applied in cement plant different cement mill, different kinds of clinker grinding process, have obtained significant grinding effect, improve the output of ball mill 20%~25%, energy saving 18%~20%, reduce ball consumption about 18%, and will not cause steel corrosion. Using sodium lignosulfonate as cement grinding aid, the specific surface area of grinding products can be increased by 200cm/g; The content of 60μm and 10μm particles in milling products decreased by 54% and 18%, while the content of 10~30um and 30~60μm particles increased by 31% and 18%, respectively. The 3-day, 7-day and 28-day compressive strength increased by 16.35%, 14% and 7.5%, respectively, and the bending strength also increased. It is a very ideal and efficient grinding aid.
