1. Inert Alumina Ceramic Ball It's broadly utilized as the covering or supporting materials of the catalyst in the reactors and the packing in the columns in such varied areas, for example, petroleum, chemical industry, chemical fertilizer, natural gas, and environmental protection etc. There are lots of merits for it, for instance, the stronger resistance to high temperature and high pressure, lower ratio of the moisture absorbing, more stable chemical properties, and so on. It is capable of enduring the corrosion of acid, alkali, and organic solvent. In addition, it can also bear the rapid transitions of temperature during the operation. In fact, its principal functions are to accelerate the distribution of gas or liquid, and support or protect the active catalyst, which especially has the relevantly lower mechanical strength. 2. Alumina Grinding Ball High strength, good abradability, high density, high efficicy, suitable for dry wet grinder, especially for high-speed grinder 3. Multi-hole ceramic ball AL2O3 content: 20%--90%, Bulk density: 1100-1550kg/m2, void volume: >=50%, catalyst supporting and covering with high void valume and low pressure drop. 4. Micro-pore ceramic ball Diameter: 0. 5-35/35-100/100-1000mm, porosity ratio: 15-40%, crushing strength: 500-7500N, catalyst supporting and covering packing or carrier with the pacity to filter the gum solid partile in the oil. 5. MF ceramic ball AL2O3 content: 20%--90%, Bulk density: 1100-1500kg/m3, void volume: >=50%, catalyst supporting and covering with high viod valume and low pressure drop. 6. Thermal Storage Ball Bulk density: 1200-1500 kg/m3, specific heat: >=850J/Kg. K, available temperature: 300-10000C, Theromal storage packing in the heat exchanger of the air perating industry. 7. Refractory Ceramic Ball Bulk density: 1200-1400 kg/m3, Alkali resistance: >=85%, refractoriness>=15000C, catalyst supporting and covering used in the shifter and reformer of the ammonia plan. 8. Multi-hole Striated Ball AL2O3 content: 20%--90%, Bulk density: 1400-1850kg/m3, crushing strength: >=500N/cm, catalyst supporting and covering or carrier.
