The flash dryer's host inner cylinder, drying chamber, cyclone separator, bag filter and other key components, as well as the parts that come into contact with the material, are usually made of stainless steel, such as SUS304 stainless steel. This material has good corrosion resistance and high temperature resistance, and can meet the drying needs of a variety of materials. The external structure of the equipment, such as the shell, bracket, etc., is often made of carbon steel and other materials to reduce costs and ensure sufficient strength and stability.
1. Host and key components: External structure: Specific component materials
• Screw feeder: The feeding pipe of the screw feeder is usually made of stainless steel, such as φ159 or φ180 stainless steel pipe, to ensure that the material enters the host continuously and evenly. At the same time, the upper part of the screw is often designed with an arch-breaking device to prevent the material from bridging.
• Blower and induced draft fan: The blades and shells of the blower and induced draft fan are often made of carbon steel or stainless steel to adapt to different working environments and media.
• Filter: The primary filter is often made of carbon steel + polyester non-woven fabric and other materials to filter large particles of impurities in the air. Medium efficiency filters may use finer filter materials to improve the filtering effect.
• Bag filter: The bags of bag filter often use three-proof bags (anti-static, oil-proof, and waterproof), made of stainless steel plates or special synthetic fibers to improve dust removal efficiency and the service life of the bags.
2. Special material selection
• Corrosion-resistant materials: According to different environments and application requirements, flash dryers can also be made of corrosion-resistant materials such as alloy steel containing elements such as nickel, chromium, aluminum, silicon, and titanium to adapt to more severe working environments.
• Non-metallic materials: If conditions permit, some parts of the flash dryer can also be made of non-metallic materials such as nylon cloth, plastic, and porcelain to reduce equipment costs and improve the corrosion resistance of the equipment.
In summary, the material selection of flash dryer equipment should be based on specific application scenarios and needs to ensure that the equipment can meet production requirements and achieve the best economic benefits.
