Lithium hydroxide monohydrate continuous disc dryer

Lithium hydroxide monohydrate is the raw material for preparing lithium compounds and can also be used in metallurgy, petroleum, glass, ceramics and other industries. Battery-grade lithium hydroxide monohydrate is mainly used for the preparation of positive electrode materials for lithium-ion batteries, and can also be used as an additive for alkaline battery electrolytes.
Lithium hydroxide monohydrate is extremely corrosive and can absorb carbon dioxide from the air and deteriorate. It is strongly alkaline and may produce harmful toxic fumes when burned. It should be operated in a closed manner to prevent dust from being released into the workshop air and avoid contact with oxidants, acids, and carbon dioxide.

Product Introduction:
During the drying process, the lithium hydroxide monohydrate to be dried is continuously added to a drying plate of the equipment through a feeder, and the rake arm with rakes rotates to make the rake arm rotate and make the rakes continuously turn over the lithium hydroxide monohydrate. Along the exponential spiral line, the lithium hydroxide monohydrate flows over the surface of the drying plate, is moved to the outer edge again on the small drying plate, and falls to the large drying plate below from the outer edge. On the large drying plate, the material moves inward and falls into the small drying plate of the next layer from the middle drop port. The large and small drying plates are arranged alternately up and down, and lithium hydroxide monohydrate flows continuously through the entire dryer. The heating medium is introduced into the hollow drying plate. The heating medium is in the form of saturated steam, hot water, heat transfer oil and high-temperature molten salt. The heating medium enters from one end of the drying plate and is discharged from the other end. The dried lithium hydroxide monohydrate falls from the bottom layer of the drying plate to the bottom layer of the shell and is moved by rakes to the discharge port for direct packaging. The evaporated moisture is discharged from the moisture discharge port on the top cover.

Product excellence:
1. Continuous operation, and high thermal efficiency. The disc continuous dryer dries by conduction heat transfer. During the drying process, only a very small amount (or no) of air is introduced into the dryer, and the exhaust gas carries very little, so its thermal efficiency can reach more than 65%.
2. Low power consumption and low noise. Since the material layer is very thin during the drying process, the spindle speed is low, the power required by the material conveying system is small, and the power consumption is very low. The power consumption of the whole set of drying equipment is only 1/5~1/7 of the power consumption of the convection heat transfer device, which reduces the operating cost and makes very little noise.
3. The material is heated evenly and the drying time is short. Since the material rolls along the Archimedean spiral motion trajectory in the drying plate during the drying process, the distance traveled by the material is 5 times the radius of the drying plate, and it falls layer by layer, so the material contacts the heating plate surface for basically the same time and is heated evenly.
4. The equipment is closed and continuously operated, with a large drying capacity and low labor intensity for workers.
5. The whole set of equipment is in a dry and closed environment, which prevents dust from overflowing and ensures the cleanliness of the operating environment.
