The Difference between Aluminum Chlorohydrate Spray Process and Drum Process
According to the different drying processes, there are mainly two types of aluminum chlorohydrate: drum process and spray process.
Drum Process: The aluminum chlorohydrate produced through the drum process is in granular form. It is dried by introducing heat-conducting oil into the drum. The difference in particle size between the two drying processes leads to different dissolution rates of the products. Aluminum chlorohydrate produced through the spray process, which is in powdered form, dissolves faster than the drum process. The larger particles of aluminum chlorohydrate in the drum process result in less dust during dosing, making it favored by on-site workers.
Spray Process: The spray process involves atomizing the aluminum chlorohydrate using a centrifuge and then drying it with water steam in a drying tower. The spray process can only be dried using a self-owned boiler with natural gas (to reduce air pollution, we choose cleaner natural gas as the energy source). On the other hand, the drum process can utilize industrial waste heat from power plants, carbon factories, and other sources, making it more cost-effective.
