Copper mud dryer

Main features of copper mud dryer：

1. Copper mud dryer has strong overload resistance, large processing capacity, low fuel consumption, and low drying cost;

2. The device adopts a co current drying method, where flue gas and wet materials enter the drying equipment from the same side. It can use high-temperature flue gas to achieve high evaporation intensity, with low outlet temperature and high thermal efficiency of the dryer;

3. This device can change its operating parameters according to the properties of different materials, so that the materials can form a stable fully broken fabric curtain inside the dryer equipment cylinder, and the mass and heat exchange is more sufficient;

4. The new feeding and discharging device of this drying equipment eliminates the phenomena of feeding blockage, discontinuity, unevenness, and return of materials in the drum dryer, and reduces the load of the dust removal system;

5. The new internal structure of this dryer enhances the cleaning and heat conduction of dispersed materials, eliminates the sticking phenomenon on the inner wall of the cylinder, and has stronger adaptability to material moisture and viscosity;

6. Zero horizontal thrust has been achieved, greatly reducing the wear of the gear wheel and ensuring smooth and reliable operation of the cylinder;

7. Adopting a "self-aligning supporting wheel device", the fit between the supporting wheel and the rolling ring is always in linear contact, thereby reducing wear and power loss;

8. This drying equipment can control the particle size and moisture content of the product according to user requirements. When drying copper paste, the moisture content of the product can reach below 8%, and the particle size can be controlled below 8mm.

Working principle:
Due to its certain viscosity, copper paste is divided into the following working areas after entering the dryer during the drying process: first, the material guide area. Wet copper paste enters this area and quickly evaporates water when it comes into contact with high-temperature hot air. Under the action of the large guide angle plate, the material cannot form a bond and is then introduced into the next working area; The second is the cleaning area, where the wet copper paste is lifted up by the board and forms a material curtain state. When the material falls, it is easy to form a bonding roller wall phenomenon. In this area, due to the design of the drying equipment with a cleaning device, the cleaning device effectively cleans the material adhered to the inner wall. During this process, the cleaning device also breaks the material clumps, thereby increasing the heat exchange area and improving the drying rate; The third is the inclined material lifting plate area, where the wet copper mud has become in a low moisture and loose state, and the material no longer has any bonding phenomenon. After heat exchange, the material reaches the required moisture state and enters the final discharge area; The fourth is the discharge area, where the drum does not have a plate, and the material rolls and slides to the discharge port, completing the entire drying process.

Application scope of copper mud dryer
