Liquid Copper Powder Vacuum Rotary Dryer
Introduction
The liquid copper powder vacuum rotary dryer is used to turn liquid copper powder or copper-containing slurry into a fine, dry powder by eliminating moisture. This dryer ensures that the copper powder maintains its purity while undergoing effective drying by fusing the concepts of vacuum technology with rotary drum drying.
Working principle
To speed up the drying process, the liquid copper powder vacuum rotary dryer rotates a cylindrical drum. In order to guarantee that the material flows continuously from one end to the other during the drying process, the drum is usually slightly angled.After entering the drum, the liquid copper powder is heated and shaken mechanically.By exposing the liquid surface to the hot air, this agitation promotes evaporation.
One important factor in lowering the pressure inside the drying chamber is the vacuum system. More effective evaporation at lower temperatures is made possible by decreased pressure, which lowers the boiling point of water and other solvents. This aids in keeping the copper powder from oxidizing or breaking down while it dries.The dryer can efficiently remove moisture at lower temperatures by employing vacuum conditions, which is crucial for fragile materials like copper that may otherwise oxidize or degrade at higher temperatures.

Material Characteristic
Copper powder is a finely ground form of copper that is often made by reduction, electrolysis, or powder metallurgy. Numerous industries, including electronics, metallurgy, coatings, chemicals, and metal additives, use copper powder. The size, form, purity, and other parameters of the copper powder determine its properties.

FAQ
1.Q: Why use a liquid copper powder vacuum rotary dryer to process copper powder?
A: Copper powder, especially liquid or paste copper powder, is highly sensitive to high temperatures. The use of liquid copper powder vacuum rotary dryer can prevent oxidation, reduce energy consumption, and protect sensitive materials, etc.
2.Q: What types of materials can be processed in a liquid copper powder vacuum rotary dryer?
A: Although the liquid copper powder vacuum rotary dryer is mainly used for copper powder, the vacuum rotary dryer can be used to dry various sensitive materials, including copper and other metal powders, pharmaceutical products,food ingredients, chemical compounds, thermosensitive materials, and so on.
3.Q: What is the capacity of a liquid copper powder vacuum rotary dryer for copper powder?
A:The capacity of the liquid copper powder vacuum rotary dryer varies depending on the design and the specific model. Typically, capacities range from small laboratory-scale dryers (a few kilograms per batch) to large industrial units capable of handling several tons per day. The drying time depends on factors such as the moisture content of the copper powder, the vacuum pressure, and the temperature used.
