Which is the best iron oxide red manufacturer in Zibo?

think everyone is already familiar with iron oxide red! Do you know the refining process of iron oxide red? Let us introduce it to you from a professional perspective. Would you be interested in this? Looking forward to your reading! The editor below will introduce to you the refining process of iron oxide red. To obtain stable iron oxide red, solid purification technology such as iron oxide powder must be used, such as water washing and grinding.
Iron oxide red refining process. The silicon-removed iron oxide powder is transported from the original acid regeneration station to the primary screening tank in the solid purification room through the negative pressure gas from the iron oxide powder warehouse. After primary screening, it enters the water washing tank by gravity. The water washing tank is filled with pure water to remove the iron. The powder and water are mixed to form iron powder slurry, and then gravity enters the secondary screening tank. The iron powder slurry coming out of the secondary screening tank gravity flows into the mixing tank. Through stirring, the impurities in the iron powder are fully dissolved into the water. The mud coming out of the mixing tank is used. The mud is pumped to the filter press for dehydration. The dehydrated mud cake is sent to the vibrating screen to separate the finer particles. The dried iron powder is dried in the drying furnace and then sent to the vibrating ball mill for grinding to meet the finished product requirements. Finally, it passes through the negative pressure gas Transported to the iron oxide red warehouse for packaging and shipping.
