porcelain ball

Ceramic ball, also known as packing ball or ceramic ball, is an industrial material widely used in industries such as petroleum, chemical, fertilizer, natural gas, environmental protection, metallurgy, sulfuric acid, etc. It is mainly used as a covering support material and tower packing for catalysts in reactors. It can buffer the impact of liquid and gas entering the reactor on the catalyst, protect the catalyst, and improve the distribution of liquid and gas in the reactor. It can also be used as a grinding medium. This product is divided into filler and grinding categories: filler categories include inert alumina ceramic balls, microporous ceramic balls, etc. The fluid distribution and impurity filtration are optimized through differences in alumina content (30% -99%) and surface opening and microporous design; Grinding is mainly made of silicon carbide and high aluminum materials, and is used for material crushing due to its high hardness. Inert ceramic balls have the characteristics of high temperature and high pressure resistance, acid and alkali corrosion resistance, and strong chemical stability. They are sintered from industrial alumina and refractory kaolin, and can withstand temperatures up to 1900 degrees Celsius

Common specifications: 3mm, 5mm, 6mm, 8mm, 13mm, 16mm, 19mm, 25mm, 38mm, 50mm

Product Introduction

Ceramic ball, also known as packing ball or ceramic ball, is an industrial material widely used in the petroleum, chemical, fertilizer, natural gas, and environmental protection industries. It is mainly used as a covering support material for catalysts in reactors and tower packing, and can also be used as a grinding medium. Ceramic balls have the characteristics of high temperature and high pressure resistance (up to 800 ℃), low water absorption, resistance to acid and alkali corrosion, and strong chemical stability. They can withstand corrosion from acids, alkalis, and other organic solvents, as well as temperature changes during production. Its main function is to increase the distribution points of gas or liquid, support and protect active catalysts with low strength. Ceramic balls can be divided into three types according to their uses: filler ceramic balls (also known as inert ceramic balls), wet grinding ceramic balls, and dry grinding ceramic balls

  • Ceramic balls can be divided into two main systems based on their main uses: filler ceramic balls and grinding ceramic balls.
  • Filler ceramic balls can be divided into ordinary ceramic balls (Al ₂ O3 about 17-23%), inert alumina ceramic balls (Al ₂ O3 23-30%), medium alumina ceramic balls (Al ₂ O3 47-56%), high alumina ceramic balls (Al ₂ O3 90-92%), and pure alumina ceramic balls (Al ₂ O3 99%) according to their main component aluminum oxide (Al ₂ O3) content.
  • According to specific functions and structures, filler ceramic balls also include convex concave groove perforated ceramic balls, active ceramic balls, perforated ceramic balls, microporous ceramic balls, thermal storage ceramic balls, refractory balls, wear-resistant ceramic balls, porous striped ceramic balls, etc. The ceramic ball with convex and concave groove openings increases the specific surface area and porosity through the design of openings and surface grooves, reducing system resistance. The porosity of microporous ceramic balls is 20-30% higher than that of inert ceramic balls, which can effectively filter impurities in oil. Fire resistant balls are mainly used for supporting catalysts and covering fillers in the converter and converter of synthetic ammonia plants; Wear resistant ceramic balls are also used in similar situations.
  • Grinding ceramic balls can be mainly divided into high alumina grinding ceramic balls, microcrystalline medium alumina grinding ceramic balls, silicon carbide grinding ceramic balls, silicon nitride grinding ceramic balls, etc. according to their materials. Among them, in 2015, China pioneered the “ceramic grinding body for cement grinding” in the world, which belongs to dry grinding ceramic balls. Its alumina content exceeds 90% and modified toughening trace elements (such as zirconium, manganese, copper, etc.) are added.

  1. Inert ceramic balls are widely used as catalyst support and covering materials, reactor fillers, and catalyst carriers due to their high chemical inertness, excellent mechanical strength, good thermal stability, and uniform porosity. They are mainly applied in multiple industrial fields.
  2. In the petrochemical industry, inert ceramic balls are used in refining, catalytic cracking (FCC), hydrogenation refining and other units as catalyst support beds to prevent catalyst particle loss and optimize fluid distribution. For example, in reforming reactors, they can effectively protect precious metal catalysts and improve reaction efficiency; In the chemical industry, fixed bed reactors used for the synthesis of ammonia, methanol, ethylene, and other chemical products are used as fillers to improve heat and mass transfer efficiency, reduce pressure drop, and lower energy consumption.
  3. In the field of environmental protection and exhaust gas treatment, inert ceramic balls are used as catalyst carriers in systems such as flue gas desulfurization (FGD) and VOCs catalytic combustion to improve exhaust gas treatment efficiency and extend catalyst life; In the pharmaceutical and food industries, it is used for the synthesis of pharmaceutical intermediates, refining of food grade solvents, and other fields that require high purity. Due to its non polluting and non leaching characteristics, it has become an ideal filler; In other industrial applications, it can also be used in the power industry such as flue gas purification in coal-fired power plants, in the metallurgical industry such as gas purification towers, and in the water treatment industry such as biofilter fillers.
  4. Inert ceramic balls are specifically used in natural gas drying adsorbers, full distillate oil hydrogenation units, flue gas to acid converters, converters for ammonia urea synthesis, alkylation reactors, methanol synthesis towers, and other devices.

  1. Strict moisture-proof storage: Although sintered before leaving the factory, some low aluminum or microporous ceramic balls have water absorption properties and should be stored in a dry and ventilated place. After unpacking, they should be used as soon as possible to avoid moisture absorption, which may cause a decrease in strength or affect fluid distribution.
  2. Standardize the loading process:
  3. Before loading, it is necessary to thoroughly clean the debris inside the tower and mark the height lines of each layer on the inner wall.
  4. It is strictly prohibited for personnel to directly step on the porcelain ball layer. Wooden boards should be laid to disperse the load and prevent breakage or bed displacement.
  5. Following the principle of “bigger at the bottom and smaller at the top”, the bottom layer is supported by larger particles, while the upper layer gradually decreases to optimize distribution. Each layer needs to be leveled to ensure levelness.
  6. Avoid mechanical impact: Handle with care during transportation, and use cloth bags or soft containers to cushion when lifting into the tower to prevent hidden cracks caused by high-altitude throwing.
  7. Regular pressure drop monitoring: Monitor the bed pressure drop during operation. If there is an abnormal increase, it may indicate that the ceramic balls are broken, powdered, or blocked, and need to be promptly checked and replaced. ‌‌
