Abstract: With the rapid development of titanium dioxide industry，there is increasingly high demand for separation equipment in the titanium dioxide production with sulfuric acid process.In order to meet the market demand，new type LWLC450×1250 helical-conveyer sedimentation filtering centrifuge which was used in the titanium dioxide production with sulfuric acid process was developed.Results indicated that the total titanium mass concentration of liquid phase separated by this new centrifuge was higher than 160 g/L and the titanium mass fraction of solid was lower than 0.41%.This new centrifuge could significantly improve the quality and yield of the titanium liquid，effectively save energy and reduce consumption，and could improve the working environment. Therefore， it is an ideal separation equipment in the titanium dioxide industry.

Key words: centrifuge, titanium dioxide, ferrous sulfate, energy saving
