Product Description
Inert Ceramic Ball Support Media: Key Features and Applications
1. Core Characteristics
-
- Material Composition: Made from high-quality chemical-porcelain clay, ensuring:
- Exceptional thermal shock resistance (withstands rapid temperature changes).
- High mechanical strength (crush resistance >1,500 kg/cm²).
- Chemical inertness (resists acids, alkalis, and corrosive gases).
- Uniformity: Precision-fired for consistent size (3-100 mm diameter) and spherical shape, optimizing flow distribution.
2. Primary Applications
Catalyst Bed Support:
Used as bottom/top layers in reactors to:
Reduce pressure drop across the bed.
Distribute gas/liquid flow evenly.
Prevent catalyst pellet loss.
Compatible with all catalyst types (e.g., alumina, zeolite, metal-based).
- High-Temperature Processes:
- Suitable for steam reforming, hydrocracking, and sulfur recovery units (operating up to 1,000°C)
- Environmental Systems:
- Used in scrubbers and biofilters to support media in waste gas treatment.
3. Selection Criteria
Size: Choose based on reactor diameter (e.g., 25-50 mm for large beds).
- Grade:
- Standard: For temperatures <800°C.
- High-Alumina: For extreme thermal/chemical conditions.
4. Industry Standards
Complies with ASTM D3802 (chemical resistance) and ISO 9001 (manufacturing quality).

Inert porcelain ball has the characteristics of high strength,high chemical stability and thermal stability,inert porcelain ball can withstand high temperature,high pressure and acid,alkali,salt and various organic solvents corrosion,inert porcelain ball is widely used in petroleum,chemical industry,fertilizer,environmental protection and other industries.the inert porcelain ball is used as the supporting and covering material of the catalyst in the reactor,which can buffer the impact of the liquid and gas entering the reactor on the catalyst,protect the catalyst,and improve the distribution of the liquid in the reactor.
The classification of inert porcelain balls includes two kinds of packing porcelain balls and grinding porcelain balls.packing ceramic balls are widely used in petroleum,chemical industry,fertilizer and environmental protection industries.is used as the covering supporting material and tower packing of catalyst in reactor.grinding class porcelain ball is mainly used in ball mill,cylindrical grinding machine vibration grinding machine,fine crushing equipment of grinding medium,has high hardness,large volume density,advantages of corrosion resistance,its grinding efficiency and wear resistance significantly better than ordinary or natural pebble stone,in ceramics,enamel,glass,paint chemical and other industries widely used.
