Lithium carbonate, an inorganic compound with the chemical formula Li2CO3, is a colorless monoclinic crystal or white powder. Density: 2.11g/cm ³. Melting point: 723℃(1.013 × 10^5Pa). Soluble in dilute acid. Slightly soluble in water, its solubility in cold water is greater than that in hot water. Insoluble in alcohol and acetone. It can be used to make ceramics, drugs, catalysts, etc. Common raw materials for lithium-ion batteries.
The material used in this test, lithium carbonate, is the raw material for lithium-ion cells. The test equipment selected is solid vacuum low-temperature drying equipment. The solvent content of the test material, lithium carbonate, is 7%, and the solvent is water. The distribution method is up and down floating. The moisture content of the dried lithium carbonate dry powder is less than 0.2%.
The principle of lithium carbonate vacuum dryer and lithium carbonate belt drying equipment:
According to the size of the customer's production capacity, 3 to 11 layers of conveyor belts are designed and arranged in the vacuum container. Through continuous solid feeders and distributors, the raw materials that the customer needs to dry are continuously fed under vacuum conditions and evenly distributed on the drying belt. As the materials are constantly turned over during the drying process, the evaporation speed and time are accelerated. To ensure the uniformity of the product during the drying process, the drying temperature can be adjusted within the range of 20 to 150℃.
The time from the material entering the dryer to the discharge after drying can be adjusted to approximately 20 to 80 minutes. If the dried product requires a crushing process, it can be crushed under vacuum conditions, which avoids dust flying, increases the product yield and solves problems such as pollution.
The dried products are continuously discharged through vacuum continuous discharger and vacuum collector, and at the same time, organic solvents can be recovered, which solves the environmental protection problem and increases the revenue from solvent recovery.
