20TPH Kaolin Dryer Plant
This 20 tons per hour industrial-grade kaolin dryer plant is a mature, cost-effective standardized medium-capacity model tailored for medium-scale kaolin processing projects. It perfectly matches the production rhythm of 150,000-ton annual output kaolin processing lines, ceramic raw material production workshops, and papermaking filler processing bases. It can stably process raw wet kaolin with 25%-40% initial moisture, and the final moisture of the dried finished kaolin is strictly controlled below 1%, fully preserving the whiteness, particle fineness and mineral crystal structure of kaolin, meeting the high-grade raw material standards for papermaking coating, high-end ceramics and paint fillers.
Core System Configuration & Working Principle
The whole plant consists of a sealed quantitative feeding device, main high-efficiency kaolin rotary dryer, clean heat supply system, multi-stage bag dust removal device, finished product closed conveying system and full intelligent constant-temperature control unit. The main dryer adopts a patented three-zone low-temperature gradient heat exchange structure, with all material contact parts made of polished food-grade stainless steel. The built-in anti-sticking self-cleaning device completely eliminates the common pain point of sticky kaolin adhering to the drum wall. The supporting multi-stage pulse bag dust removal system achieves a dust collection rate of 99.9%, no fine kaolin 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 plant is only 220 ㎡, 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 42% compared with old-fashioned kaolin dryers, which can save more than 700,000 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 12mm thick high-quality stainless 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 16 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 natural gas, biomass, clean coal and industrial waste heat, 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 plant easily.
Short delivery and commissioning cycle: The mature standardized plant can be delivered within 30 days after the order is confirmed, and the on-site installation and commissioning can be completed in 9 days, allowing you to put the project into production quickly.
This 20TPH kaolin dryer plant has been verified by more than 60 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.
