Q: What is the difference between alumina ceramic balls and ordinary ceramic packing balls?
A: High-alumina ceramic balls have a higher Al₂O₃ content, higher compressive strength, and better acid and alkali resistance and high-temperature resistance. They are less prone to breakage and pulverization under high temperature, high pressure, or corrosive conditions, and have a significantly longer service life than ordinary ceramic balls. They are more suitable for catalyst bed support and filling of critical process sections.
Q: What are the common specifications and sizes of alumina ceramic balls?
A: Common specifications include 3mm, 6mm, 10mm, and 50mm. They can be laid in a multi-layered gradation method according to the device structure, with larger load-bearing particles at the bottom and progressively smaller particles at the top to achieve better gas-liquid distribution and lower system pressure drop. Zibo Xiangrun Environmental Engineering Co., Ltd. can provide alumina ceramic balls in different sizes from 0.5-95mm.
Q: How should I choose the appropriate alumina content grade?
A: Common content grades are 92%, 95%, and 99%. For routine filling and general reaction conditions, 92% high-alumina ceramic balls can be used. In high-temperature, high-pressure applications or where bed stability is critical, it is recommended to use 95% or higher high-purity alumina ceramic balls to achieve higher mechanical strength and longer service life.
Q: Will the alumina ceramic balls pulverize or break during use?
A: High-quality alumina ceramic balls produced using a high-temperature sintering process have excellent wear resistance and thermal shock resistance, and are not prone to pulverization or breakage under normal operating conditions.
Q: Will alumina ceramic balls affect the chemical properties of the reaction system?
A: High-purity alumina ceramic balls are chemically stable and inert. They do not participate in the reaction, do not introduce impurities, and will not affect catalyst activity. They are suitable for chemical and fine chemical plants with high process purity requirements.
Q: What is the normal service life of alumina ceramic balls?
A: Under stable operating conditions, alumina ceramic balls can typically be used for more than 5 years. Many plants do not require replacement of the support ball layer during multiple catalyst replacement cycles. Proper selection and correct installation methods can further extend their actual service life.
Q: What technical indicators should be focused on when purchasing alumina ceramic balls?
A: It is recommended to focus on indicators such as alumina content, compressive strength, bulk density, water absorption rate, abrasion rate, and dimensional tolerances. These parameters directly affect the bed's load-bearing capacity, long-term stability, and the safety of equipment operation.
