  • Rotary Drum Dryer

    The working temperature of rotary drum dryer machine can reach up to 150℃-180℃ and the water content of wood shavings is below 10% after drying. Simple design, self-insulation, and improving the heat efficiency to exceed 80%. Meantime, good drying performance, coal consumption 8kg when drying 1 ton material

  • Co-Current Vs. Counter Current Drying

    The Co-Current Rotary Dryer. Best for: Materials that are heat-sensitive, maintaining product quality (NOTE: 90% of all rotary dryers are co-current for these reasons) Key Advantages: Greater control over solids temperature and avoidance of overheating. Disadvantages: Slightly less thermally efficient than counter-current air flow. Co-current

  • External Factors That Impact the Drying Effect of Rotary

    Mar 11, 2017 The drying effect of rotary dryer is affected by many factors, and today the large-scale professional rotary dryer manufacturer---Fote Machinery will mainly introduce some external factors to you, including the ambient humiture, the wet material type, the initial moisture content, the final moisture content and the hot air temperature


    Rotary Dryers are one of the widely used Dryer in process industry. Especially in fertilizer and minerals industry for drying products such as coal, clay, gypsum, kaolin, limestone, mineral sand, potash, silica sand etc. Rotary Dryers from SAKA provide controlled, uniform and efficient drying to help you achieve desired product quality

  • Rotary Dryer drying process:

    Jan 14, 2022 Organic fertilizer Rotary dryer drying mode: The two drying methods of the organic fertilizer Rotary dryer are the direct drying method and the indirect drying method. The direct drying method uses a heat carrier such as high-temperature gas to directly contact the material, which can make good use of combustion

  • Rotary Dryer Working Principle, Design,Drying System , Uses

    Rotary drum dryers can be designed in stainless steel or carbon steel materials. If the product is corrosive, stainless steel can be used instead of carbon steel. If the product is food grade, food grade stainless steel such as SUS304 can be used. carbon steel drums are designed to withstand inlet temperatures of 530 c – 600 c

  • Rotary Dryers - an overview | ScienceDirect Topics

    Drying temperatures should be limited to 315 C (600 F) to avoid degradation of xanthophylls and producing a darker colored coproduct. The rotary dryer has the advantage of making a non-dusty product, whereas the flash dried product is less dense and brighter in color because the product is exposed to less drying time
