Rotary Dryer or Air Dryer?

Users preparing to invest in machine-made charcoal production will face a common choice: which is better, rotary dryer or air dryer? Actually, both types of dryers have their own characteristics. Here, a highly-experienced technician from Zhengyang Machinery will make a comparison between the two, just for your information.

Rotary Dryer Advantages:

1. Good drying effect. The rotary dryer is able to satisfy the material requirement of producing machine-made charcoal, that is, the percentage of moisture is at 7%-13%, which greatly improves the production efficiency; 2. Large output. The smallest size is enough to satisfy the production requirement of two briquette machines. Disadvantages: The price of rotary dryer is a little higher, even the smallest size requires about RMB 30,000 in China.

Air Dryer

Advantages: The price is comparatively lower, less than RMB 15,000 in China, which is more attractive for small-scale charcoal producers.

Disadvantages: Unstable drying effect. If the moisture content is too high, it possibly needs secondary drying. From the above, for machine-made charcoal producers, both rotary dryer and air dryer have their merits and demerits, as well as their user groups. Therefore, potential machine-made investors can make a decision according to your own actual situations.
