This 30 tons per hour industrial-grade gypsum rotary dryer is a mature, cost-effective standardized model tailored for medium-scale gypsum resource utilization projects. It is perfectly suited for scenarios such as 200,000-ton annual output desulfurization gypsum/phosphogypsum processing stations, supporting drying links for medium-sized gypsum powder production lines, and on-site treatment of large stockpiles of wet industrial by-product gypsum. It can stably process raw gypsum with 25%-40% initial moisture, and output dried finished gypsum with final moisture precisely controlled below 5%, fully meeting the national standards for high-quality building gypsum, cement retarder and gypsum board raw materials.
Core Design & Working Principle
This 30TPH model adopts our exclusive three-zone anti-sticking gradient temperature control rotary drum structure. The wet gypsum first enters the pre-dispersion pre-drying zone, where high-speed hot air instantly breaks up sticky gypsum clumps and evaporates most surface moisture, eliminating the material's viscosity in advance to avoid adhesion to the drum wall. Then the material is lifted and scattered by specially designed layered cascading lifting plates in the main high-efficiency heat exchange zone, forming a uniform full-section material curtain that fully contacts with hot air, making the heat exchange efficiency 2.5 times higher than that of traditional single-cylinder dryers. Finally, the material enters the constant-temperature stabilization zone, where internal bound moisture is fully evaporated under precisely controlled temperature to ensure uniform and stable finished product quality. The supporting two-stage cyclone dust collector + pulse bag dust removal system captures more than 99.95% of fine gypsum dust in exhaust gas, achieving zero material loss and fully compliant emission. The built-in flue gas waste heat recovery system recycles over 75% of residual heat from exhaust gas to preheat incoming cold air, further boosting overall thermal efficiency to 81%.
Standout Advantages
Excellent cost performance for medium-scale projects: The whole machine covers an area of only 220 ㎡, with low requirements for plant foundation, and the total investment is far lower than that of large-scale custom drying lines. The optimized energy-saving design cuts comprehensive energy consumption by over 42% compared with old-fashioned dryers, helping you recover the full investment in 9-11 months.
Extremely low failure rate and easy operation: The main drum is made of 14mm 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 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 operating cost by 25%-32%.
Short delivery and installation cycle: The standardized mature model can be delivered within 30 days after the order is confirmed, and on-site installation and commissioning can be completed in only 9 days, allowing you to put the project into production quickly and seize the market opportunity.
