30TPH Slag Dryer System
This 30 tons per hour industrial-grade slag dryer system is a mature, cost-effective standardized medium-capacity model tailored for medium-scale industrial slag resource utilization projects. It perfectly matches the production rhythm of 200,000-ton annual output slag processing lines, medium-sized steel plant solid waste treatment workshops, and building material production bases that use slag as raw materials. It can stably process various industrial slags including blast furnace slag, steel slag and non-ferrous metal smelting slag with 20%-32% initial moisture, and the final moisture of the dried finished slag is strictly controlled below 3%, fully meeting the quality requirements of high-value products such as cement admixture, road base material and mineral powder raw materials.
Core System Configuration & Working Principle
The whole system consists of a quantitative feeding device, main high-efficiency slag rotary dryer, special heat supply system, multi-stage dust removal device, finished product conveying system and full intelligent control unit. The main dryer adopts a patented three-zone gradient heat exchange structure, with all material contact parts made of thickened high-chromium wear-resistant alloy. The built-in anti-sticking self-cleaning device completely eliminates the common pain point of slag adhering to the drum wall. The supporting two-stage cyclone dust collector + pulse bag dust removal system achieves a dust collection rate of 99.9%, no fine material loss, and the emission fully meets the national environmental protection standards. The built-in flue gas waste heat recovery system recycles more than 75% of the residual heat from the exhaust gas, boosting the overall system thermal efficiency to over 80%.
Outstanding Practical Advantages
Excellent cost performance: The total floor area of the whole set of system is only 260 ㎡, with low requirements for plant foundation, and the comprehensive investment is far lower than that of split large drying lines. The optimized energy-saving design reduces the unit energy consumption by more than 43% compared with old-fashioned slag dryers, which can save more than 850,000 RMB on energy costs every year, and the full investment can be recovered within 10 months.
Extremely high durability and low failure rate: The main drum is made of 14mm thick high-manganese wear-resistant steel, and the service life of the lifting plate and other vulnerable parts is more than 3 times longer than that of ordinary products. The heavy-duty transmission system supports 24-hour continuous full-load operation for more than 30 days, with a design service life of over 17 years, and the annual failure rate is lower than 0.7%.
High flexibility for multi-scenario adaptation: It supports a variety of heat source options such as industrial waste heat, natural gas, biomass and coal, and you can choose the most cost-effective configuration according to your local on-site conditions, which can further reduce the operating cost by 28%-35%. The full PLC intelligent control system only needs 1 operator to manage the whole system easily.
Short delivery and commissioning cycle: The mature standardized system can be delivered within 32 days after the order is confirmed, and the on-site installation and commissioning can be completed in 10 days, allowing you to put the project into production quickly.
This 30TPH slag dryer system has been verified by more than 70 stable industrial operation cases, with extremely reliable performance. We provide full one-stop services including free on-site survey, customized layout design, installation guidance, operator training and 18-month full warranty.
