Compact Drum Dryer For Drying High-Humidity Materials In Agriculture And Chemical Industries

Compact Design Drum Dryer With Low Cost and High Efficiency

Product Introduction

1, Structure of drum dryer
The main body of a drum dryer is a rotating cylinder that is slightly inclined from the horizontal line, driven by gears, with a speed of generally 2-6 r/min. The inclination of the cylinder is related to its length, usually between 1-5.
It is mainly composed of rotating body, lifting plate, transmission device, support device, sealing ring and other components.
 

2, Working principle
The material is fed from the higher end of the rotary drum and comes into contact with hot air. As the cylinder rotates, the material flows towards the lower end under the action of gravity and is dried before being discharged. The dryer operates under negative pressure conditions, and sealing devices are used at both the feeding and discharging ends to prevent air leakage.
The material enters the drum through the feeding device and is continuously picked up and scattered in a spiral motion under the action of the lifting plate to achieve drying heat exchange. The material that achieves the drying standard quickly moves out of the drum under the action of hot air, while the wet material that does not achieve the drying standard cannot move quickly due to its own weight. It is fully dried in the lifting plate and discharged to achieve the drying purpose.

3, Applicable materials
In the agriculture, feed, and fertilizer industries, it is suitable for starch residue, medicinal residue, fruit residue, sugarcane bagasse, organic compound fertilizer, sludge, etc. It is also widely used for drying alfalfa grass, DDGS, sawdust, etc.
In industries such as chemical, mining, and metallurgy, it can be used for drying materials such as ores, slag, and metal powders.

4, Product Features
Equipment structure
Adopting a self-aligning tugboat structure, the cooperation between the tugboat and the rolling ring is good, greatly reducing wear and power consumption.
The specially designed gear wheel structure greatly reduces the horizontal thrust caused by the tilting operation of the equipment, has strong overload resistance, and the cylinder runs smoothly with high reliability.
Performance
►High processing capacity, low fuel consumption, and low drying cost.
►The distribution and angle design of the lifting plate are reasonable, the performance is reliable, the heat energy utilization rate is high, the drying is uniform, the number of material cleaning times is small, and it is suitable for easy maintenance.
►It has the characteristic of high temperature resistance and can use high-temperature hot air to quickly dry materials.
►Strong scalability, designed with production margin in mind, even if the output increases slightly, there is no need to replace equipment.
►The thermal efficiency can reach up to 80%, reducing energy consumption and saving costs.
