Coal is an important energy resource, but the water content of newly mined coal is high, which is not conducive to subsequent utilization. To solve this problem, the rotary dryer has become an ideal choice for the coal industry to process coal and water-containing materials due to its advantages of high efficiency, energy saving and environmental protection.

  The rotary dryer is a device that evenly distributes the material in the drum through the rotating drum, and uses the hot air to fully contact the material to achieve rapid drying. The material is repeatedly thrown by the lifting plate in the drum to form a stable material curtain, thereby improving the heat exchange efficiency. It is suitable for drying various materials such as coal, coal slime, fly ash, slag, etc.

  Technical advantages of coal rotary dryer

  1. High efficiency and energy saving, high thermal efficiency

  Adopting the downstream drying method, the flue gas and wet materials enter from the same side, the high-temperature flue gas is fully in contact with the materials, and the evaporation intensity is high. The thermal efficiency can reach more than 80%, which is more than 35% higher than the traditional single-drum dryer. There is no air leakage, good sealing, and high thermal energy utilization.

  2. Strong processing capacity and strong adaptability

  The processing capacity of a single machine can reach 300~3000 tons/day, which is suitable for large-scale production. The operating parameters such as air volume, wind direction, temperature, etc. can be adjusted according to the properties of the material to achieve flexible control. It has strong adaptability to materials and can handle a variety of materials such as lignite, coal slime, slag, etc.

  3. Energy saving and environmental protection, in line with environmental protection requirements

  Adopting a closed structure to reduce dust and exhaust gas emissions, equipped with dust removal equipment to meet environmental protection requirements. Hot air is recycled to reduce fuel consumption and reduce carbon emissions. Adopting an intelligent control system to achieve remote monitoring and automatic adjustment, improve production efficiency and environmental protection level.

  4. Easy operation and low maintenance cost

  Easy operation, one-button start, high degree of automation, and reduced manual intervention. Compact structure, easy maintenance, only regular cleaning and inspection are required. Made of high-quality stainless steel, it is corrosion-resistant, high-temperature-resistant, and has a long service life.
