Material Overview

Lithium hydroxide is a white monoclinic fine crystal. It's spicy. Highly alkaline. It absorbs carbon dioxide and moisture in the air. Lithium hydroxide can be used as a developer and lubricant for spectral analysis.

It can be used as an additive for alkaline battery electrolytes, which can increase the capacitance by 12% to 15%, and increase the service life by 2 to 3 times. Used for making lithium salts and lithium-based lubricants, electrolytes for alkaline batteries, absorption liquids for lithium bromide refrigerators, etc.; when used in alkaline batteries, the aluminum content shall not exceed 0.06%, and the lead content shall not exceed 0.01%. It is used as an analytical reagent, photographic developer, and also in the manufacture of lithium; it is used as a raw material for preparing lithium compounds. It can also be used in metallurgy, petroleum, glass, ceramics and other industries.

1.processing advantages

This time, our company is in the original discdrying equipmentDetailed adjustments have been made to make it better dry lithium hydroxide. First of all, the connection structure of the rake blades of the equipment has been changed, which has high flexibility and is convenient to adjust according to the specific gravity of the material. At the same time, this design does not need to remove the rake rods when repairing and replacing the rake blades; due to the relatively small particle size of the battery material powder, it is easy to fall into the bottom layer during the falling process, and uneven drying will cause the fine powder to penetrate into the bearings. Our company has made special improvements to this situation, adding a labyrinth seal in the middle of the last layer of discharge tray, allowing the material on the upper plate to smoothly slide along the cone and enter the discharge tray when falling, preventing the occurrence of fine powder entering the bearing; Secondly, the heat source of the tray dryers designed by manufacturers in the same industry has a single inlet, and there is a short circuit in the heat source in the plate, and the material on the plate is unevenly heated. However, our company designs dual (multiple) inlets and dual (multiple) outlets, which makes the heat source distribution more uniform when entering and exiting, and the materials on the plate absorb more fully, which greatly improves the thermal efficiency.

2.equipment characteristics

1 Continuous operation, high thermal efficiency. The disc continuous dryer dries by conduction and heat transfer. During the drying process, only a very small amount (or no) of air is introduced into the dryer, and the amount of exhaust gas carried is very small, so its thermal efficiency can reach more than 65%.

2 Low power consumption and low noise. Because 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 small. The power consumption of the complete drying device is only 1/5 to 1/7 of the power consumption of the convective heat transfer device., and the noise is very low.

3 The material is evenly heated and the drying time is short. During the drying process, the material rolls along the trajectory of the Archimedes spiral in the drying plate, and the distance traveled by the material is 5 times the radius of the drying plate and falls layer by layer, so the material contacts the heating plate surface for basically the same time, and the heat is very uniform.

4. Low cost of the dryer system: With a huge heat transfer surface per unit effective volume, the processing time is shortened and the equipment size becomes smaller. The building area and building space are greatly reduced.

5 Low environmental pollution: no carrying air is used, and very little dust materials are entrained. Material solvent evaporation is very small, easy to handle. Closed circulation can be used for contaminated materials or working conditions where solvent recovery is required.

6 Low operating costs: The equipment operates normally, only 1 hour/day/person. Low speed mixing and reasonable structure. The amount of wear is small and the maintenance cost is very low.

7 The drying process uses less gas, low flow rate, and less dust is carried away by the gas: Therefore, it is convenient to recover gas dust after drying, and the recycling equipment is simple, saving equipment investment. For drying processes with solvent recovery, the solvent concentration in the gas can be increased, reducing the number of solvent recovery equipment or shortening the process
