Lithium carbonate caustic method is to mix lithium carbonate and refined lime milk at a molar ratio of 1:1.08, adjusting the concentration of caustic solution to 18~20g/ L, heating to boiling and stirring strongly.Time of controlling the caustic is 30min.After centrifugation,CaCO3 precipitation and lithium hydroxide mother liquor with a concentration of about 3.5% were obtained. The mother liquor was evaporated, concentrated, crystallized and dried to produce monohydrate lithium hydroxide product.
The disadvantages of traditional drying process are its high cost due to several stage requirement and the usage of lime,causing waste generation.The main objective of vacuum belt dryer is to demonstrate the feasibility of obtaining battery grade lithium hydroxide monohydrate.
The advantages of Vacuum Belt Dryer：
Continuous feed and discharge under vacuum state
Pipelined,continuous and automates drying process
Adjustable Drying Temperature 20-200 degree centigrade,low Temperature
Chemical drying process:Hydration and Dehydration Reaction
⅓ Running cost of traditional drying process
Full enclosed and simplified process,no contamination
CIP cleaning system,fulfill GMP requirement
Drying time 20-150mins
PLC control system
Vacuum belt dry for powder&particle
Can solve existing issues of traditional dryers:
Metal magnetic foreign substance exceeds the limit
CO3 2-(Carbonate ion)exceeds the standard level
Air outlet causing powder running away,the on-site operation lead to unfriendly environment
Easy to agglomerate,uneven moisture content directly impact
