amixon® mixer/dryer for lithium salts
Vacuum mix dryers from amixon® are ideal for the efficient and economical drying of lithium derivatives and lithium salts.
Lithium salts for lithium-ion batteries must be extremely pure and dry. Lithium salts include lithium oxide, lithium fluoride, lithium carbonate, lithium hydroxide and lithium chloride. Many processing steps are necessary to obtain the pure lithium salt. Almost every chemical process step ends with a drying process and blending process. Vacuum mix dryers from amixon® are ideal for the efficient and economical drying of lithium derivatives and lithium salts.
Vacuum mix dryers for lithium salts
On the basis of drying tests, amixon® can calculate very accurate projections for a wide range of drying volumes and equipment dimensions . We can also extrapolate how the drying time changes when drying takes place at higher or lower temperatures. This is also possible in cases where the mixing tool works with modified rotation frequencies.
The same applies to the calculation of the cooling time if the dry goods are to be cooled in the same vacuum mixer dryer. When calculating the cooling time, we take into account the batch size and cooling media of different temperatures.
amixon® vacuum mixer dryers are particularly suitable for drying lithium salts for the following reasons:
• The process chamber is highly clean. It is "technically tight" within the definition of TA-Luft. No particles escape, nor are foreign particles or ambient air introduced.
• Drying takes place at low speeds. The relative speeds are generally 0.8 to 1.3 m/s. This means that there is practically no abrasion and no particle destruction.
• The vacuum lowers the product temperature and accelerates evaporation.
• Extremely short drying times if a "cooling mixer" is installed under the vacuum mixer dryer. amixon® devices have a long service life despite abrupt "hot/cold changes".
• Heat transfer is extremely fast due to constant contact with the appliance surfaces.
• All appliance surfaces are heated - including the mixing shaft, the mixing arms and the spiral.
• After drying, an amixon® mixer dryer empties itself completely.
• The feeding and discharge fittings can be coupled with containment systems. This ensures a high level of product purity.
• If required, metal oxides can be added and mixed in the same mix dryer.
Vacuum drying processes can be demonstrated in the amixon® test center
A visit to amixon® is always worthwhile. You will learn a lot from talking to our experts in process engineering, design and production technology. amixon® manufactures all components itself and controls all quality-relevant breakpoints. Tests with your mixing goods will certainly lead to good results. This secures your investment decision. Calcination processes at higher temperatures can also be performed in the amixon® test center. Optionally, higher system pressures can also be used.
