We often say that the scientific name of rust red is iron oxide red, the method of its production can be divided into natural and synthetic two. Iron oxide red is mainly used as pigment, such as concrete and other building materials coloring, oil paint coloring agent, etc. Iron oxide red is widely used in construction, rubber, plastics and other industries, in addition to iron oxide red primer can effectively prevent rust.

iron oxide red drying process:
In the process of synthetic iron oxide red, due to its large water content. Therefore, it is necessary to use drying equipment for processing. The traditional method is mainly through mechanical dehydration, followed by drying in an oven. The drying process increases and the drying cycle increases, which is no longer applicable. changzhou city easy degree drying equipment limited company recommend use flash drying equipment for drying iron oxide red material. See Iron Oxide Flash Drying Process for details.
Flash dryer is a new type of drying technology introduced into China in recent years. This technology combines fluidization technology and drying technology. Its applicable material state includes filter cake material, slurry material, paste material, etc.
iron oxide red flash drying equipment:
Flash drying equipment for drying iron oxide red materials consists of the following three parts: flash dryer: flash dryer mainly includes feeding system, crushing fluidization system and drying system; Heating system: The heating system can flexibly select oil, gas and coal-fired hot blast stoves for more energy consumption and cost. Collection system: mainly includes cyclone separator and bag filter.
Iron oxide red flash dryer working principle:
The air enters the heating system through the filter and enters the flash drying host tangentially from the air inlet after heating. The material enters the drying equipment from the feeding system and is cut by the crushing system installed at the bottom. The hot air blows the material to the top of the flash host, and the material is sheared and crushed to fully exchange heat with the hot air. The water inside the material evaporates and rises to the top to be discharged and collected by the receiving system. The iron oxide red material that has not been dried settles to the bottom again and repeats the above steps.
Flash dryer processing iron oxide red advantages:
1 iron oxide red material through the flash dryer rapid drying completed into powder. Since the finished product is required to be a powder of a certain particle size, it eliminates the need for crushing and other processes compared to other drying technologies.
2 There is no environmental pollution problem: the flash dryer system is slightly negative pressure, and the collection system is equipped with a cyclone separator and a bag filter double collection system to prevent the leakage of materials into the air and cause pollution.
3 Good drying effect: Using a flash dryer, its drying cycle is short, the drying effect is good, and there is no material discoloration.
4 Low energy consumption and large processing capacity.
