Special coal cinder for preparing porcelain tile
The invention discloses special coal cinder for preparing a porcelain tile. The special coal cinder is pretreated through the following steps of (1) sieving the raw material of the coal cinder; (2) recovering iron in the sieved coal cinder through magnetic separation equipment; (3) adding water into the magnetically-separated coal cinder, and carrying out ball milling treatment; (4) adding water into the ball-milled coal cinder, and recovering iron powder through iron removal equipment; (5) adding a bleaching agent into the iron-removed coal cinder, and carrying out sedimentation and bleaching treatment through a sedimentation tank; (6) carrying out filter pressing treatment on the settled coal cinder through a filter press; and (7) drying the coal cinder subjected to filter pressing to obtain a finished product containing less than 0.5% of TiO2, less than 0.05% of V2O5 and less than 0.5% of Fe. By using the special coal cinder, the ball milling efficiency is increased, the iron removal effect is improved, the whiteness of a product is greatly improved, and the removed harmful substances can be recovered.
