| description | Disclosed is a raw material pre-treatment process system suitable for a kiln phosphoric acid process, comprising a carbonaceous reductant, a phosphate ore and a silica pre-treatment system which are independent from one another, outlets of the carbonaceous reductant, phosphate ore pre-treatment system and silica pre-treatment system are all connected to an inner pellet material mixing device via a first delivery device, and outlets of the carbonaceous reductant and the silica pre-treatment system are both additionally connected to a shell material mixing device via a second delivery device. Also disclosed is a raw material pre-treatment process suitable for a kiln phosphoric acid process, i.e. pre-treating carbonaceous reductant, phosphate ore and silica respectively, feeding the carbonaceous reductant powder, phosphate ore powder and silica powder into the inner ball material mixing device for pelletizing, and feeding the carbonaceous reductant and silica into the shell material mixing device for mixing. |
