Ternary precursor experimental line: The simplified process mainly includes salt, alkali and ammonia conformation process, crystallisation reaction process, constant temperature aging, washing and drying process. The liquid nickel sulphate, cobalt sulphate and newly purchased crystal manganese sulphate prepared in the previous process are accurately weighed by an automatic weighing instrument, and then added to the salt-making kettle with pure water to make a certain proportion of sulphate solution (the salt-making kettle needs to be heated with a heating wire (60°C),( 68135446, 67488162,32%) of alkaline solution, the two above are sent to the corresponding tanks by pumps, and processed by precision filters for use in the corresponding tanks. The sulphate solution and the alkaline aqueous solution, purchased or reused for water treatment of ammonia, are stored for use in two tanks. The sulphate solution and alkaline aqueous solution, purchased or water-treated ammonia…
