1. What is rotary drum drying plant applicable for?

Rotary drum drying plant is widely used in agriculture, forestry, construction, metallurgy, chemical and cement-making industry. It is mainly composed of rotating cylinder, lifting board, transmission device, supporting device and seal ring. Rotary drum drying plant has the advantages of reasonable structure, unique design, high capacity, low consumption, convenient operation.

2. How does rotary drum drying plant work?

The main body of rotary drum drying plant is a cylinder at a certain gradient with horizon. The cylinder is drove by gear at a speed of 2-6r/min. The general gradient of cylinder is about 1°-5°. Materials enter cylinder by the upper end. As the cylinder rotates, materials flow to the lower end under gravity and get discharged. During this period, materials get thorough contact with hot air, moisture inside gets vaporized. Due to rotary drum drying plant operates under negative pressure, the inlet and outlet both adopt sealing device to avoid air leakage.

3. What’s the features of rotary drum drying plant?

1. We adopt combined type of lifting device to overcome the “air tunnel” phenomenon. High heat efficiency, energy consumption reduced about 20%.

2. Different types of furnace for actual condition: high temperature boiling furnace, coal power spraying furnace, coal furnace.

3. Pin-changeable gear replaces the traditional cast steel gear. This saves the investment and also reduces maintainance cost and time.

4. Adoption of central control system to realize management by computer for enterprise.
