20TPH Fly Ash Dryer Machine
This 20 tons per hour industrial-grade fly ash dryer machine is a mature, cost-effective standardized model tailored for small and medium-sized fly ash resource utilization projects. It is perfectly suited for scenarios such as 300,000-ton annual output fly ash processing stations, supporting drying links for small cement admixture production lines, and on-site treatment of wet fly ash stockpiled in small and medium-sized thermal power plants. It can stably process raw wet fly ash with 20%-30% initial moisture, and output dried finished fly ash with final moisture controlled below 1%, fully meeting the national standards for high-quality cement admixture and building material raw materials.
Core Design & Working Principle
This 20TPH model adopts our exclusive three-zone anti-flying and anti-sticking rotary drum structure. The wet fly ash first enters the material guiding pre-drying zone, where it is quickly scattered by the high-speed hot air flow to evaporate most of the surface moisture, eliminating the viscosity of the material in advance to avoid adhesion. Then the material is lifted and scattered by the specially designed lightweight material lifting plates in the main heat exchange zone, forming a uniform suspended material curtain that fully contacts with hot air for efficient heat exchange, avoiding the problem of light fly ash being taken away by the flue gas. Finally, the material enters the constant-temperature deep drying zone to complete the evaporation of internal bound moisture, and is discharged after being slightly cooled. The supporting two-stage cyclone dust collector + bag dust removal system captures more than 99.9% of the fine fly ash dust in the exhaust gas, achieving zero material loss and fully compliant emission.
Standout Advantages
Ultra-high cost performance for small and medium projects: The whole machine covers an area of only 180 ㎡, with low requirements for plant foundation, and the total investment is far lower than that of large-scale drying lines. The optimized heat exchange structure makes the thermal efficiency as high as 82%, and the comprehensive energy consumption per ton of dried fly ash is only 1/2 of that of traditional old-fashioned dryers, helping you recover the full investment in 8-10 months.
Extremely low failure rate and easy operation: The main drum is made of 12mm thick high-quality carbon steel, with wear-resistant alloy reinforced lifting plates, and the service life of vulnerable parts is more than 3 times longer than ordinary products. Equipped with a full PLC intelligent control system, only 1 operator can manage the whole machine easily, no complex professional operation skills are required.
High flexibility for multi-scenario adaptation: It supports multiple heat source options such as coal-fired hot blast stove, biomass burner, natural gas and industrial waste heat. You can choose the most cost-effective heat source configuration according to your local on-site conditions, which can further reduce the operating cost by 20%-30%.
Short delivery and installation cycle: The standardized mature model can be delivered within 25 days after the order is confirmed, and the on-site installation and commissioning can be completed in only 7 days, allowing you to put the project into production quickly and seize the market opportunity.
