Triple Cylinder Rotary Dryer is an efficient rotary drum dryer with a three-layer insulation effect and a self insulating structure for circulation. Triple Cylinder Rotary Dryer is consists of an inner cylinder, a middle cylinder, and an outer cylinder forming a self insulated circulating structure, which has high working efficiency, energy saving, and environmental protection.
Triple Cylinder Rotary Dryer is mainly used to dry granular materials within a certain humidity range, such as yellow sand used in the dry powder mortar industry and various specifications of molding sand used in the casting industry; Blast furnace slag used in the building materials and cement industry; Small particle clay is used in the chemical industry for small particle materials that do not undergo chemical changes, are not afraid of high temperatures, and are not contaminated by smoke and dust.
According to the requirements of different industries for the final moisture content of dried materials, the moisture content of dried materials can reach below 1-0.5%.
Triple Cylinder Rotary Dryer Internal Structure
The first level drying area uses co current high-temperature drying. Under high humidity conditions, after passing through an inlet temperature of 430 ℃ (which can reach up to 600 ℃), it instantly exchanges heat and mass with the material, removing most of the moisture and ensuring that the calorific value of the material does not change;
The secondary drying zone uses counter current drying at a room temperature of 300 ℃, which is a high-yield water removal zone. During the reverse drying process, the material is ensured to be agile and dry;
The third level drying area is a normal drying area with an indoor temperature of 120 ℃ -210 ℃. It uses crushing equipment inside the drum to repeatedly pull, hit, and scatter, and dries downstream;
The fourth level drying zone is a high exhaust zone that uses a negative pressure high-temperature hot air flow under the effect of induced draft to remove moisture, with a room temperature of 60 ℃ -80 ℃;
The drying of materials is carried out step by step, and through the above operations, the heating value of the materials is increased after drying compared to before drying, and the moisture content is kept within 0.8%, which truly achieves the effect of energy saving and consumption reduction.
Triple Cylinder Rotary Dryer Features
1. The Triple Cylinder Rotary Dryer is made of wear-resistant manganese plate, which is 3-4 times more wear-resistant than ordinary steel plate.
2. The initial moisture content of the material is 15%, and the final moisture content is ensured to be below 0.5-1%. It is an ideal equipment for drying various products such as slag powder and dry powder mortar production lines in cement plants.
3. Improved thermal efficiency by over 60% compared to traditional single drum dryers.
4. The fuel can be used for white coal, bituminous coal, coal gangue, oil, and steam; Capable of drying block, granular, and powdered materials below 20-40mm.
5. Reduce the footprint by about 60% compared to a single rotary drum dryer; Reduce civil engineering investment by about 60% and facilitate installation.
6. Coal consumption is one-third of that of a single rotary drum dryer, saving 40% of electricity.
