Three-return drying equipment
Three-return dryer, that is, an efficient combination dryer. It adopts the latest energy-saving technology in Europe-the clamp-type structure. The inner tube, the middle tube and the outer tube form a self-insulating structure. At the same time, the drum is outsourced with insulation materials and stainless steel plates to further reduce heat loss. Improve thermal efficiency. The special thermal design concept eliminates wind tunnel heat loss, increases heat exchange area and volume evaporation intensity, and saves energy. It conforms to the international policy of creating an environment-friendly and resource-saving society, and is an environmentally-friendly and energy-saving product that replaces traditional drying equipment . This equipment is used to dry yellow sand, river sand, quartz sand, slag, clay and other raw materials. It is widely used in building materials, chemical industry, foundry and other industries.
1. Equipment investment is 20% of imported products. It is made of wear-resistant manganese plate, which is 3-4 times more wear-resistant than ordinary steel plates.
2. The initial moisture content of the material is 15%, and the final moisture content is guaranteed to be less than 0.5-1%. It is the preferred product for various drying projects such as cement plant slag powder and dry powder mortar production lines.
3. Compared with the traditional single-cylinder dryer, it can improve the thermal efficiency by more than 40%.
4. Fuel can be suitable for white coal, bituminous coal, coal gangue, oil and steam. Can bake blocks, granules and powdery materials below 20-40mm.
5. Compared with the single cylinder dryer, it occupies about 60% less floor space. Civil construction investment is reduced by about 60% and installation is convenient.
6, no air leakage phenomenon, completely solved the difficulty of sealing.
7, discharge temperature ≤ 60 degrees, can be directly fed into the warehouse, without cooling into the cooling shed.
8. The temperature of the outer cylinder is ≤60 degrees, the temperature of the exhaust gas is <120 degrees, and the service life of the bag of the dust removal equipment is more than 2 times longer.
9. Coal consumption is 1/3 of that of single-cylinder dryer, which saves electricity by 40%, and the standard coal consumption per ton is less than 9 kg.
